An AES (Rijndael) Implementation in C/C++ (as specified in FIPS-197)
====================================================================
Changes in this Version (16/04/2007)
====================================
These changes remove errors in the VC++ build files and add some
improvements in file naming consitency and portability. There are
no changes to overcome reported bugs in the code.
1. gen_tabs() has been renamed to aes_init() to better decribe its
function to those not familiar with AES internals.
2. via_ace.h has been renamed to aes_via_ace.h.
3. Minor changes have been made to aestab.h and aestab.c to enable
all the code to be compiled in either C or C++.
4. The code for detecting memory alignment in aesmdoes.c has been
simplified and a new routine has been added:
aes_test_alignment_detection()
to check that the aligment test is likely to be correct.
5. The addition of support for Structured Exception Handling (SEH)
to YASM (well done Peter and Michael!) has allowed the AMD64
x64 assembler code to be changed to comply with SEH requriements.
6. Corrections to build files (for win32 debug build).
Overview
========
This code implements AES for both 32 and 64 bit systems with optional
assembler support for x86 and AMD64/EM64T (but optimised for AMD64).
The basic AES source code files are as follows:
aes.h the header file needed to use AES in C
aescpp.h the header file required with to use AES in C++
aesopt.h the header file for setting options (and some common code)
aestab.h the header file for the AES table declaration
aescrypt.c the main C source code file for encryption and decryption
aeskey.c the main C source code file for the key schedule
aestab.c the main file for the AES tables
brg_types.h a header defining some standard types and DLL defines
brg_endian.h a header containing code to detect or define endianness
aes_x86_v1.asm x86 assembler (YASM) alternative to aescrypt.c using
large tables
aes_x86_v2.asm x86 assembler (YASM) alternative to aescrypt.c using
compressed tables
aes_amd64.asm AMD64 assembler (YASM) alternative to aescrypt.c using
compressed tables
In addition AES modes are implemented in the files:
aes_modes.c AES modes with optional support for VIA ACE detection and use
aes_via_ace.h the header file for VIA ACE support
Other associated files for testing and support are:
aesaux.h header for auxilliary routines for testsing
aesaux.c auxilliary routines for testsingt
aestst.h header file for setting the testing environment
rdtsc.h a header file that provides access to the Time Stamp Counter
aestst.c a simple test program for quick tests of the AES code
aesgav.c a program to generate and verify the test vector files
aesrav.c a program to verify output against the test vector files
aestmr.c a program to time the code on x86 systems
modetest.c a program to test the AES modes support
vbxam.doc a demonstration of AES DLL use from Visual Basic in Microsoft Word
vb.txt Visual Basic code from the above example (win32 only)
aesxam.c an example of AES use
tablegen.c a program to generate a simplified 'aestab.c' file for
use with compilers that find aestab.c too complex
yasm.rules the YASM build rules file for Microsoft Visual Studio 2005
via_ace.txt describes support for the VIA ACE cryptography engine

Building The AES Libraries
--------------------------
A. Versions
-----------
The code can be used to build static and dynamic libraries, each in five
versions:
C uses C source code only
ASM_X86_V1C large table x86 assembler code for encrypt/decrypt
ASM_X86_V2 compressed table x86 assembler for encrypt/decrypt and keying
ASM_X86_V2C compressed table x86 assembler code for encrypt/decrypt
ASM_AMD64 compressed table x86 assembler code for encrypt/decrypt
The C version can be compiled for Win32 or x64, the x86 assembler versions
are for Win32 only and the AMD64 version for x64 only.
B. Types
--------
The code makes use of types defined as uint_<nn>t where <nn> is the length
of the type, for example, the unsigned 32-bit type is 'uint_32t'. These are
NOT the same as the fixed width integer types in C99, inttypes.h and stdint.h
since several attempts to use these types have shown that support for them is
still highly variable. But a regular expression search and replace in VC++
with search on 'uint_{:z}t' and a replace with 'uint\1_t' will convert these
types to C99 types (there should be similar search/replace facilities on other
systems).
C. YASM
-------
If you wish to use the x86 assembler files you will also need the YASM open
source x86 assembler (r1331 or later) for Windows which can be obtained from:
http://www.tortall.net/projects/yasm/
This assembler should be placed in the bin directory used by VC++, which, for
Visual Stduio 2005, is typically:
C:\Program Files (x86)\Microsoft Visual Studio 8\VC\bin
You will also need to move the yasm.rules file from this distribution into
the directory where Visual Studio 2005 expects to find it, which is typically:
C:\Program Files (x86)\Microsoft Visual Studio 8\VC\VCProjectDefaults
Alternatively you can configure the path for rules files within Visual Studio.
D. Configuration
----------------
The following configurations are available as projects for Visual Studio 2005
but the following descriptions should allow them to be built in other x86

C source: aes_modes.c
x86 assembler: aes_amd64.asm
defines ASM_X86_V2 (set for C and assembler files)
dll_asm_amd64_c x64
headers: aes.h, aesopt.h, aestab.h, brg_endian.h, tdefs,h
C source: aes_modes.c
x86 assembler: aes_amd64.asm
defines DLL_EXPORT, ASM_AMD64_C (set for C and assembler files)
Notes:
ASM_X86_V1C is defined if using the version 1 assembler code (aescrypt1.asm).
The defines in the assember file must match those in aes.h and
aesopt.h). Also remember to include/exclude the right assembler
and C files in the build to avoid undefined or multiply defined
symbols - include aescrypt1.asm and exclude aescrypt.c and
aescrypt2.asm.
ASM_X86_V2 is defined if using the version 2 assembler code (aescrypt2.asm).
This version provides a full, self contained assembler version
and does not use any C source code files except for the mutiple
block encryption modes that are provided by aes_modes.c. The define
ASM_X86_V2 must be set on the YASM command line (or in aescrypt2.asm)
to use this version and all C files except aec_modes.c and. for the
DLL build, aestab.c must be excluded from the build.
ASM_X86_V2C is defined when using the version 2 assembler code (aescrypt2.asm)
with faster key scheduling provided by the in C code (the options in
the assember file must match those in aes.h and aesopt.h). In this
case aeskey.c and aestab.c are needed with aescrypt2.asm and the
define ASM_X86_V2C must be set for both the C files and for
asecrypt2.asm command lines (or in aesopt.h and aescrypt2.asm).
Include aescrypt2.asm aeskey.c and aestab.c, exclude aescrypt.c for
this option.
ASM_AMD64_C is defined when using the AMD64 assembly code because the C key
scheduling is sued in this case.
DLL_EXPORT must be defined to generate the DLL version of the code and
to run tests on it
DLL_IMPORT must be defined to use the DLL version of the code in an
application program
Directories the paths for the various directories for test vector input and
output have to be set in aestst.h
VIA ACE see the via_ace.txt for this item
Static The static libraries are named:
Libraries
aes_lib_generic_c.lib
aes_lib_asm_x86_v1c.lib
aes_lib_asm_x86_v2.lib
aes_lib_asm_x86_v2c.lib
aes_lib_asm_amd64_c.lib
and placed in one of the the directories:
lib\win32\release\
lib\win32\debug\
lib\x64\release\
lib\x64\debug\
in the aes root directory depending on the platform(win32 or
x64) and the build (release or debug). After any of these is
built it is then copied into aes.lib, which is the library
that is subsequently used for testing. Hence testing is for
the last static library built.
Dynamic The static libraries are named:
Libraries
aes_lib_generic_c.dll
aes_lib_asm_x86_v1c.dll
aes_lib_asm_x86_v2.dll
aes_lib_asm_x86_v2c.dll
aes_lib_asm_amd64_c.dll
and placed in one of the the directories:
dll\win32\release\
dll\win32\debug\
dll\x64\release\
dll\x64\debug\
in the aes root directory depending on the platform(win32 or
x64) and the build (release or debug). Each DLL library:
aes_<ext>.dll
has three associated files:
aes_dll_<ext>.lib the library file for implicit linking
aes_dll_<ext>.exp the exports file
aes_dll_<ext>.pdb the symbol file
After any DLL is built it and its three related files are then
copied into aes.lib, aes.lib, aes,exp and aes.pdb, which are
the libraries used for testing. Hence testing is for the last
static library or DLL built.
E. Testing
----------
These tests require that the test vector files are placed in the 'testvals'
subdirectory. If the AES Algorithm Validation Suite tests will be use3d then
the *.fax files need to be put in the 'testvals\fax' subdirectory. This is
covered in more detail below.
The projects test_dll and time_dll are used to test and time the last DLL
built. These use the files:
test_dll: Win32 (x64 for the C and AMD64 versions)
headers: aes.h, aescpp.h, brg_types.h, aesaux.h and aestst.h
C source: aesaux.c, aesrav.c
defines: DLL_IMPORT
time_dll: Win32 (x64 for the C and AMD64 versions)
headers: aes.h, aescpp.h, brg_types.h, aesaux.h aestst.h and rdtsc.h
C source: aesaux.c, aestmr.c
defines: DLL_IMPORT
and link to the DLL using explicit linking. However, if the lib file associated
with the DLL is linked into this project and the symbol DYNAMIC_LINK in aestst.h
is left undefined, then implicit linking will be used
The projects test_lib and time_lib are used to test and time the last static LIB
built. They use the files:
test_lib: Win32 (x64 for the C and AMD64 versions)
headers: aes.h, aescpp.h, brg_types.h, aesaux.h and aestst.h
C source: aesaux.c, aesrav.c
defines:
time_lib: Win32 (x64 for the C and AMD64 versions)
headers: aes.h, aescpp.h, brg_types.h, aesaux.h, aestst.h and rdtsc.h
C source: aesaux.c, aestmr.c
defines:
and link to the last static library built.
The above test take command line arguments that determine which test are run
as follows:
test_lib /t:[knec] /k:[468]
test_dll /t:[knec] /k:[468]
where the symbols in square brackets can be used in any combination (without
the brackets) and have the following meanings:
/t:[knec] selects which tests are used
/k:[468] selects the key lengths used
/c compares output with reference (see later)
k: generate ECB Known Answer Test files
n: generate ECB Known Answer Test files (new)
e: generate ECB Monte Carlo Test files
c: generate CBC Monte Carlo Test files
and the characters giving the lengths are digits representing the lengths in
32-bit units.\n\n");
The project test_modes tests the AES modes. It uses the files:
test_modes: Win32 or x64
headers: aes.h, aescpp.h, brg_types.h, aesaux,h and aestst.h
C source: aesaux.c, modetest.c
defines: none for static library test, DLL_IMPORT for DLL test
which again links to the last library built.
F. Other Applications
---------------------
These are:
gen_tests builds the test_vector files. The commad line is
gen_tests /t:knec /k:468 /c
as described earlier
test_aes_avs run the AES Algorithm Validation Suite tests for
ECB, CBC, CFB and OFB modes
gen_tables builds a simple version of aes_tab.c (in aestab2.c)
for compilers that cannot handle the normal version
aes_example provides an example of AES use
These applications are linked to the last static library built or, if
DLL_IMPORT is defined during compilation, to the last DLL built.
G. Use of the VIA ACE Cryptography Engine
-----------------------------------------
The use of the code with the VIA ACE cryptography engine in described in the
file via_ace.txt. In outline aes_modes.c is used and USE_VIA_ACE_IF_PRESENT
is defined either in section 2 of aesopt.h or as a compilation option in Visual
Studio. If in addition ASSUME_VIA_ACE_PRESENT is also defined then all normal
AES code will be removed if not needed to support VIA ACE use. If VIA ACE
support is needed and AES assembler is being used only the ASM_X86_V1C and
ASM_X86_V2C versions should be used since ASM_X86_V2 and ASM_AMD64 do not
support the VIA ACE engine.
H. The AES Test Vector Files
----------------------------
These files fall in the following groups (where <nn> is a two digit
number):
1. ecbvk<nn>.txt ECB vectors with variable key
2. ecbvt<nn>.txt ECB vectors with variable text
3. ecbnk<nn>.txt new ECB vectors with variable key
4. ecbnt<nn>.txt new ECB vectors with variable text
5. ecbme<nn>.txt ECB monte carlo encryption test vectors
6. ecbmd<nn>.txt ECB monte carlo decryption test vectors
7. cbcme<nn>.txt CBC monte carlo encryption test vectors
8. cbcmd<nn>.txt CBC monte carlo decryption test vectors
The first digit of the numeric suffix on the filename gives the block size
in 32 bit units and the second numeric digit gives the key size. For example,
the file ecbvk44.txt provides the test vectors for ECB encryption with a 128
bit block size and a 128 bit key size. The test routines expect to find these
files in the 'testvals' subdirectory within the aes root directory. The
'outvals' subdirectory is used for outputs that are compared with the files
in 'testvals'. Note that the monte carlo test vectors are the result of
applying AES iteratively 10000 times, not just once.
The AES Algorithm Validation Suite tests can be run for ECB, CBC, CFB and
OFB modes (CFB1 and CFB8 are not implemented). The test routine uses the
*.fax test files, which should be placed in the 'testvals\fax' subdirectory.
I. The Basic AES Calling Interface
----------------------------------
The basic AES code keeps its state in a context, there being different
contexts for encryption and decryption:
aes_encrypt_ctx
aes_decrypt_ctx
The AES code is initialised with the call
aes_init(void)
although this is only essential if the option to generate the AES tables at
run-time has been set in the options (i.e.fixed tables are not being used).
The AES encryption key is set by one of the calls:
aes_encrypt_key128(const unsigned char *key, aes_encrypt_ctx cx[1])
aes_encrypt_key192(const unsigned char *key, aes_encrypt_ctx cx[1])
aes_encrypt_key256(const unsigned char *key, aes_encrypt_ctx cx[1])
or by:
aes_encrypt_key(const unsigned char *key, int key_len,
aes_encrypt_ctx cx[1])
where the key length is set by 'key_len', which can be the length in bits
or bytes.
Similarly, the AES decryption key is set by one of:
aes_decrypt_key128(const unsigned char *key, aes_decrypt_ctx cx[1])
aes_decrypt_key192(const unsigned char *key, aes_decrypt_ctx cx[1])
aes_decrypt_key256(const unsigned char *key, aes_decrypt_ctx cx[1])
or by:
aes_decrypt_key(const unsigned char *key, int key_len,
aes_decrypt_ctx cx[1])
Encryption and decryption for a single 16 byte block is then achieved using:
aes_encrypt(const unsigned char *in, unsigned char *out,
const aes_encrypt_ctx cx[1])
aes_decrypt(const unsigned char *in, unsigned char *out,
const aes_decrypt_ctx cx[1])
The above subroutines return a value of EXIT_SUCCESS or EXIT_FAILURE
depending on whether the operation succeeded or failed.
J. The Calling Interface for the AES Modes
------------------------------------------
The subroutines for the AES modes, ECB, CBC, CFB, OFB and CTR, each process
blocks of variable length and can also be called several times to complete
single mode operations incrementally on long messages (or those messages,
not all of which are available at the same time). The calls:
aes_ecb_encrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, const aes_encrypt_ctx cx[1])
aes_ecb_decrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, const aes_decrypt_ctx cx[1])
for ECB operations and those for CBC:
aes_cbc_encrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *iv, const aes_encrypt_ctx cx[1])
aes_cbc_decrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *iv, const aes_decrypt_ctx cx[1])
can only process blocks whose lengths are multiples of 16 bytes but the calls
for CFB, OFB and CTR mode operations:
aes_cfb_encrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *iv, aes_encrypt_ctx cx[1])
aes_cfb_decrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *iv, aes_encrypt_ctx cx[1])
aes_ofb_encrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *iv, aes_encrypt_ctx cx[1])
aes_ofb_decrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *iv, aes_encrypt_ctx cx[1])
aes_ctr_encrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *cbuf, cbuf_inc ctr_inc, aes_encrypt_ctx cx[1])
aes_ctr_decrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *cbuf, cbuf_inc ctr_inc, aes_encrypt_ctx cx[1])
can process blocks of any length. Note also that CFB, OFB and CTR mode calls only
use AES encryption contexts even during decryption operations.
The calls CTR mode operations use a buffer (cbuf) which holds the counter value
together with a function parameter:
void cbuf_inc(unsigned char *cbuf);
that is ued to update the counter value after each 16 byte AES operation. The
counter buffer is updated appropriately to allow for incremental operations.
Please note the following IMPORTANT points about the AES mode subroutines:
1. All modes are reset when a new AES key is set.
2. Incremental calls to the different modes cannot
be mixed. If a change of mode is needed a new
key must be set or a reset must be issued (see
below).
3. For modes with IVs, the IV value is an inpu AND
an ouput since it is updated after each call to
the value needed for any subsequent incremental
call(s). If the mode is reset, the IV hence has
to be set (or reset) as well.
4. ECB operations must be multiples of 16 bytes
but do not need to be reset for new operations.
5. CBC operations must also be multiples of 16
bytes and are reset for a new operation by
setting the IV.
6. CFB, OFB and CTR mode must be reset by setting
a new IV value AND by calling:
aes_mode_reset(aes_encrypt_ctx cx[1])
For CTR mode the cbuf value also has to be reset.
7. CFB, OFB and CTR modes only use AES encryption
operations and contexts and do not need AES
decrytpion operations.
8. AES keys remain valid across resets and changes
of mode (but encryption and decryption keys must
both be set if they are needed).

; Issue 20/12/2007
;
; I am grateful to Dag Arne Osvik for many discussions of the techniques that
; can be used to optimise AES assembler code on AMD64/EM64T architectures.
; Some of the techniques used in this implementation are the result of
; suggestions made by him for which I am most grateful.
; An AES implementation for AMD64 processors using the YASM assembler. This
; implemetation provides only encryption, decryption and hence requires key
; scheduling support in C. It uses 8k bytes of tables but its encryption and
; decryption performance is very close to that obtained using large tables.
; It can use either Windows or Gnu/Linux calling conventions, which are as
; follows:
; windows gnu/linux
;
; in_blk rcx rdi
; out_blk rdx rsi
; context (cx) r8 rdx
;
; preserved rsi - + rbx, rbp, rsp, r12, r13, r14 & r15
; registers rdi - on both
;
; destroyed - rsi + rax, rcx, rdx, r8, r9, r10 & r11
; registers - rdi on both
;
; The default convention is that for windows, the gnu/linux convention being
; used if __GNUC__ is defined.
;
; Define _SEH_ to include support for Win64 structured exception handling
; (this requires YASM version 0.6 or later).
;
; This code provides the standard AES block size (128 bits, 16 bytes) and the
; three standard AES key sizes (128, 192 and 256 bits). It has the same call
; interface as my C implementation. It uses the Microsoft C AMD64 calling
; conventions in which the three parameters are placed in rcx, rdx and r8
; respectively. The rbx, rsi, rdi, rbp and r12..r15 registers are preserved.
;
; AES_RETURN aes_encrypt(const unsigned char in_blk[],
; unsigned char out_blk[], const aes_encrypt_ctx cx[1]);
;
; AES_RETURN aes_decrypt(const unsigned char in_blk[],
; unsigned char out_blk[], const aes_decrypt_ctx cx[1]);
;
; AES_RETURN aes_encrypt_key<NNN>(const unsigned char key[],
; const aes_encrypt_ctx cx[1]);
;

; either bits or bytes.
;
; Comment in/out the following lines to obtain the desired subroutines. These

%define AES_128 ; define if AES with 128 bit keys is needed
%define AES_192 ; define if AES with 192 bit keys is needed
%define AES_256 ; define if AES with 256 bit keys is needed
%define AES_VAR ; define if a variable key size is needed
%define ENCRYPTION ; define if encryption is needed
%define DECRYPTION ; define if decryption is needed
%define AES_REV_DKS ; define if key decryption schedule is reversed
%define LAST_ROUND_TABLES ; define for the faster version using extra tables
; The encryption key schedule has the following in memory layout where N is the
; number of rounds (10, 12 or 14):
;
; lo: | input key (round 0) | ; each round is four 32-bit words
; | encryption round 1 |
; | encryption round 2 |
; ....
; | encryption round N-1 |
; hi: | encryption round N |
;
; The decryption key schedule is normally set up so that it has the same
; layout as above by actually reversing the order of the encryption key
; schedule in memory (this happens when AES_REV_DKS is set):
;
; lo: | decryption round 0 | = | encryption round N |
; | decryption round 1 | = INV_MIX_COL[ | encryption round N-1 | ]
; | decryption round 2 | = INV_MIX_COL[ | encryption round N-2 | ]
; .... ....
; | decryption round N-1 | = INV_MIX_COL[ | encryption round 1 | ]
; hi: | decryption round N | = | input key (round 0) |
;
; with rounds except the first and last modified using inv_mix_column()
; But if AES_REV_DKS is NOT set the order of keys is left as it is for
; encryption so that it has to be accessed in reverse when used for
; decryption (although the inverse mix column modifications are done)
;
; lo: | decryption round 0 | = | input key (round 0) |
; | decryption round 1 | = INV_MIX_COL[ | encryption round 1 | ]
; | decryption round 2 | = INV_MIX_COL[ | encryption round 2 | ]
; .... ....
; | decryption round N-1 | = INV_MIX_COL[ | encryption round N-1 | ]
; hi: | decryption round N | = | encryption round N |
;
; This layout is faster when the assembler key scheduling provided here
; is used.
;
; The DLL interface must use the _stdcall convention in which the number
; of bytes of parameter space is added after an @ to the sutine's name.
; We must also remove our parameters from the stack before return (see
; the do_exit macro). Define DLL_EXPORT for the Dynamic Link Library version.

These subroutines implement multiple block AES modes for ECB, CBC, CFB,
OFB and CTR encryption, The code provides support for the VIA Advanced
Cryptography Engine (ACE).
NOTE: In the following subroutines, the AES contexts (ctx) must be
16 byte aligned if VIA ACE is being used

; Issue 13/08/2008
;
; This code requires ASM_X86_V1C to be set in aesopt.h. It requires the C files
; aeskey.c and aestab.c for support.
; An AES implementation for x86 processors using the YASM (or NASM) assembler.
; This is an assembler implementation that covers encryption and decryption
; only and is intended as a replacement of the C file aescrypt.c. It hence
; requires the file aeskey.c for keying and aestab.c for the AES tables. It
; employs full tables rather than compressed tables.
; This code provides the standard AES block size (128 bits, 16 bytes) and the
; three standard AES key sizes (128, 192 and 256 bits). It has the same call
; interface as my C implementation. The ebx, esi, edi and ebp registers are
; preserved across calls but eax, ecx and edx and the artihmetic status flags
; are not. It is also important that the defines below match those used in the
; C code. This code uses the VC++ register saving conentions; if it is used
; with another compiler, conventions for using and saving registers may need to
; be checked (and calling conventions). The YASM command line for the VC++
; custom build step is:
;
; yasm -Xvc -f win32 -o "$(TargetDir)\$(InputName).obj" "$(InputPath)"
;
; The calling intefaces are:
;
; AES_RETURN aes_encrypt(const unsigned char in_blk[],
; unsigned char out_blk[], const aes_encrypt_ctx cx[1]);
;
; AES_RETURN aes_decrypt(const unsigned char in_blk[],
; unsigned char out_blk[], const aes_decrypt_ctx cx[1]);
;
; AES_RETURN aes_encrypt_key<NNN>(const unsigned char key[],
; const aes_encrypt_ctx cx[1]);
;
; AES_RETURN aes_decrypt_key<NNN>(const unsigned char key[],
; const aes_decrypt_ctx cx[1]);
;
; AES_RETURN aes_encrypt_key(const unsigned char key[],
; unsigned int len, const aes_decrypt_ctx cx[1]);
;
; AES_RETURN aes_decrypt_key(const unsigned char key[],
; unsigned int len, const aes_decrypt_ctx cx[1]);
;
; where <NNN> is 128, 102 or 256. In the last two calls the length can be in
; either bits or bytes.
;
; Comment in/out the following lines to obtain the desired subroutines. These
; selections MUST match those in the C header file aes.h
%define AES_128 ; define if AES with 128 bit keys is needed
%define AES_192 ; define if AES with 192 bit keys is needed
%define AES_256 ; define if AES with 256 bit keys is needed
%define AES_VAR ; define if a variable key size is needed
%define ENCRYPTION ; define if encryption is needed
%define DECRYPTION ; define if decryption is needed
%define AES_REV_DKS ; define if key decryption schedule is reversed
%define LAST_ROUND_TABLES ; define if tables are to be used for last round
; offsets to parameters
in_blk equ 4 ; input byte array address parameter
out_blk equ 8 ; output byte array address parameter
ctx equ 12 ; AES context structure
stk_spc equ 20 ; stack space
%define parms 12 ; parameter space on stack
; The encryption key schedule has the following in memory layout where N is the
; number of rounds (10, 12 or 14):
;
; lo: | input key (round 0) | ; each round is four 32-bit words
; | encryption round 1 |
; | encryption round 2 |
; ....
; | encryption round N-1 |
; hi: | encryption round N |
;
; The decryption key schedule is normally set up so that it has the same
; layout as above by actually reversing the order of the encryption key
; schedule in memory (this happens when AES_REV_DKS is set):
;
; lo: | decryption round 0 | = | encryption round N |
; | decryption round 1 | = INV_MIX_COL[ | encryption round N-1 | ]
; | decryption round 2 | = INV_MIX_COL[ | encryption round N-2 | ]
; .... ....
; | decryption round N-1 | = INV_MIX_COL[ | encryption round 1 | ]
; hi: | decryption round N | = | input key (round 0) |
;
; with rounds except the first and last modified using inv_mix_column()
; But if AES_REV_DKS is NOT set the order of keys is left as it is for
; encryption so that it has to be accessed in reverse when used for
; decryption (although the inverse mix column modifications are done)
;
; lo: | decryption round 0 | = | input key (round 0) |
; | decryption round 1 | = INV_MIX_COL[ | encryption round 1 | ]
; | decryption round 2 | = INV_MIX_COL[ | encryption round 2 | ]
; .... ....
; | decryption round N-1 | = INV_MIX_COL[ | encryption round N-1 | ]
; hi: | decryption round N | = | encryption round N |
;
; This layout is faster when the assembler key scheduling provided here
; is used.
;
; The DLL interface must use the _stdcall convention in which the number
; of bytes of parameter space is added after an @ to the sutine's name.
; We must also remove our parameters from the stack before return (see
; the do_exit macro). Define DLL_EXPORT for the Dynamic Link Library version.

Issue Date: 20/12/2007
This file contains the compilation options for AES (Rijndael) and code
that is common across encryption, key scheduling and table generation.
OPERATION
These source code files implement the AES algorithm Rijndael designed by
Joan Daemen and Vincent Rijmen. This version is designed for the standard
block size of 16 bytes and for key sizes of 128, 192 and 256 bits (16, 24
and 32 bytes).
This version is designed for flexibility and speed using operations on
32-bit words rather than operations on bytes. It can be compiled with
either big or little endian internal byte order but is faster when the
native byte order for the processor is used.
THE CIPHER INTERFACE
The cipher interface is implemented as an array of bytes in which lower
AES bit sequence indexes map to higher numeric significance within bytes.
uint_8t (an unsigned 8-bit type)
uint_32t (an unsigned 32-bit type)
struct aes_encrypt_ctx (structure for the cipher encryption context)
struct aes_decrypt_ctx (structure for the cipher decryption context)
AES_RETURN the function return type
C subroutine calls:
AES_RETURN aes_encrypt_key128(const unsigned char *key, aes_encrypt_ctx cx[1]);
AES_RETURN aes_encrypt_key192(const unsigned char *key, aes_encrypt_ctx cx[1]);
AES_RETURN aes_encrypt_key256(const unsigned char *key, aes_encrypt_ctx cx[1]);
AES_RETURN aes_encrypt(const unsigned char *in, unsigned char *out,
const aes_encrypt_ctx cx[1]);
AES_RETURN aes_decrypt_key128(const unsigned char *key, aes_decrypt_ctx cx[1]);
AES_RETURN aes_decrypt_key192(const unsigned char *key, aes_decrypt_ctx cx[1]);
AES_RETURN aes_decrypt_key256(const unsigned char *key, aes_decrypt_ctx cx[1]);
AES_RETURN aes_decrypt(const unsigned char *in, unsigned char *out,
const aes_decrypt_ctx cx[1]);
IMPORTANT NOTE: If you are using this C interface with dynamic tables make sure that
you call aes_init() before AES is used so that the tables are initialised.

/* 1. BYTE ORDER WITHIN 32 BIT WORDS
The fundamental data processing units in Rijndael are 8-bit bytes. The
input, output and key input are all enumerated arrays of bytes in which
bytes are numbered starting at zero and increasing to one less than the
number of bytes in the array in question. This enumeration is only used
for naming bytes and does not imply any adjacency or order relationship
from one byte to another. When these inputs and outputs are considered
as bit sequences, bits 8*n to 8*n+7 of the bit sequence are mapped to
byte[n] with bit 8n+i in the sequence mapped to bit 7-i within the byte.
In this implementation bits are numbered from 0 to 7 starting at the
numerically least significant end of each byte (bit n represents 2^n).
However, Rijndael can be implemented more efficiently using 32-bit
words by packing bytes into words so that bytes 4*n to 4*n+3 are placed
into word[n]. While in principle these bytes can be assembled into words
in any positions, this implementation only supports the two formats in
which bytes in adjacent positions within words also have adjacent byte
numbers. This order is called big-endian if the lowest numbered bytes
in words have the highest numeric significance and little-endian if the
opposite applies.
This code can work in either order irrespective of the order used by the
machine on which it runs. Normally the internal byte order will be set
to the order of the processor on which the code is to be run but this
define can be used to reverse this in special situations
WARNING: Assembler code versions rely on PLATFORM_BYTE_ORDER being set.
This define will hence be redefined later (in section 4) if necessary

/* 4. FAST INPUT/OUTPUT OPERATIONS.
On some machines it is possible to improve speed by transferring the
bytes in the input and output arrays to and from the internal 32-bit
variables by addressing these arrays as if they are arrays of 32-bit
words. On some machines this will always be possible but there may
be a large performance penalty if the byte arrays are not aligned on
the normal word boundaries. On other machines this technique will
lead to memory access errors when such 32-bit word accesses are not
properly aligned. The option SAFE_IO avoids such problems but will
often be slower on those machines that support misaligned access
(especially so if care is taken to align the input and output byte
arrays on 32-bit word boundaries). If SAFE_IO is not defined it is
assumed that access to byte arrays as if they are arrays of 32-bit
words will not cause problems when such accesses are misaligned.

/* 12. TABLE OPTIONS
This cipher proceeds by repeating in a number of cycles known as 'rounds'
which are implemented by a round function which can optionally be speeded
up using tables. The basic tables are each 256 32-bit words, with either
one or four tables being required for each round function depending on
how much speed is required. The encryption and decryption round functions
are different and the last encryption and decrytpion round functions are
different again making four different round functions in all.
This means that:
1. Normal encryption and decryption rounds can each use either 0, 1

Issue Date: 20/12/2007
This file contains the code for declaring the tables needed to implement
AES. The file aesopt.h is assumed to be included before this header file.
If there are no global variables, the definitions here can be used to put
the AES tables in a structure so that a pointer can then be added to the
AES context to pass them to the AES routines that need them. If this
facility is used, the calling program has to ensure that this pointer is
managed appropriately. In particular, the value of the t_dec(in,it) item
in the table structure must be set to zero in order to ensure that the
tables are initialised. In practice the three code sequences in aeskey.c
that control the calls to aes_init() and the aes_init() routine itself will
have to be changed for a specific implementation. If global variables are
available it will generally be preferable to use them with the precomputed
FIXED_TABLES option that uses static global tables.
The following defines can be used to control the way the tables
are defined, initialised and used in embedded environments that
require special features for these purposes
the 't_dec' construction is used to declare fixed table arrays
the 't_set' construction is used to set fixed table values
the 't_use' construction is used to access fixed table values
256 byte tables:
t_xxx(s,box) => forward S box
t_xxx(i,box) => inverse S box
256 32-bit word OR 4 x 256 32-bit word tables:
t_xxx(f,n) => forward normal round
t_xxx(f,l) => forward last round
t_xxx(i,n) => inverse normal round
t_xxx(i,l) => inverse last round
t_xxx(l,s) => key schedule table
t_xxx(i,m) => key schedule table
Other variables and tables:
t_xxx(r,c) => the rcon table

*/
// An example of the use of AES (Rijndael) for file encryption. This code
// implements AES in CBC mode with ciphertext stealing when the file length
// is greater than one block (16 bytes). This code is an example of how to
// use AES and is not intended for real use since it does not provide any
// file integrity checking.
//
// The Command line is:
//
// aesxam input_file_name output_file_name [D|E] hexadecimalkey
//
// where E gives encryption and D decryption of the input file into the
// output file using the given hexadecimal key string. The later is a
// hexadecimal sequence of 32, 48 or 64 digits. Examples to encrypt or
// decrypt aes.c into aes.enc are:
//
// aesxam file.c file.enc E 0123456789abcdeffedcba9876543210
//
// aesxam file.enc file2.c D 0123456789abcdeffedcba9876543210
//
// which should return a file 'file2.c' identical to 'file.c'
//
// CIPHERTEXT STEALING
//
// Ciphertext stealing modifies the encryption of the last two CBC
// blocks. It can be applied invariably to the last two plaintext
// blocks or only applied when the last block is a partial one. In
// this code it is only applied if there is a partial block. For
// a plaintext consisting of N blocks, with the last block possibly

Issue Date: 20/12/2007
The unsigned integer types defined here are of the form uint_<nn>t where
<nn> is the length of the type; for example, the unsigned 32-bit type is
'uint_32t'. These are NOT the same as the 'C99 integer types' that are
defined in the inttypes.h and stdint.h headers since attempts to use these
types have shown that support for them is still highly variable. However,
since the latter are of the form uint<nn>_t, a regular expression search
and replace (in VC++ search on 'uint_{:z}t' and replace with 'uint\1_t')
can be used to convert the types used here to the C99 standard types.

Support for the VIA Nehemiah Advanced Cryptography Engine (ACE)
---------------------------------------------------------------
A. Introduction
The AES code now supports the VIA ACE engine. The engine is invoked by the
multiple block AES modes calls in aes_modes.c and not by the basic AES code.
The define USE_VIA_ACE_IF_PRESENT is defined if VIA ACE detection and use is
required with fallback to the normal AES code if it is not present.
The define ASSUME_VIA_ACE_PRESENT is used when it is known that the VIA ACE
engine will always be present. Note, however, that this code will not work
correctly if the VIA ACE engine is either not present or turned off.
To enable ACE support the appropriate defines in section 2 of the options in
aesopt.h must be set. If ACE support is required then key scheduling must
use the C code so only the generic C code in Win32 mode, ASM_X86_V1C and
ASM_X86_V2C assembler code can be used (i.e ASM_X86_V2 and ASM_AMD64_C do
NOT support VIA ACE).
B. Using ACE
ACE is used in the code that implements the subroutines used for the multiple
block AES modes defined in aes_modes.h:
// used to reset modes to their start point without entering a new key
AES_RETURN aes_mode_reset(aes_encrypt_ctx cx[1]);
AES_RETURN aes_ecb_encrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, const aes_encrypt_ctx cx[1]);
AES_RETURN aes_ecb_decrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, const aes_decrypt_ctx cx[1]);
AES_RETURN aes_cbc_encrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *iv, const aes_encrypt_ctx cx[1]);
AES_RETURN aes_cbc_decrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *iv, const aes_decrypt_ctx cx[1]);
AES_RETURN aes_cfb_encrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *iv, aes_encrypt_ctx cx[1]);
AES_RETURN aes_cfb_decrypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *iv, aes_encrypt_ctx cx[1]);
#define aes_ofb_encrypt aes_ofb_crypt
#define aes_ofb_decrypt aes_ofb_crypt
AES_RETURN aes_ofb_crypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *iv, aes_encrypt_ctx cx[1]);
typedef void cbuf_inc(unsigned char *cbuf);
#define aes_ctr_encrypt aes_ctr_crypt
#define aes_ctr_decrypt aes_ctr_crypt
AES_RETURN aes_ctr_crypt(const unsigned char *ibuf, unsigned char *obuf,
int len, unsigned char *cbuf, cbuf_inc ctr_inc, aes_encrypt_ctx cx[1]);
Note that the single block AES calls defined in aes.h:
AES_RETURN aes_encrypt(const unsigned char *in, unsigned char *out,
const aes_encrypt_ctx cx[1]);
AES_RETURN aes_decrypt(const unsigned char *in, unsigned char *out,
const aes_decrypt_ctx cx[1]);
do NOT provide ACE support and should not be used if the ACE engine is
available and ACE support is required.
C. Constraints and Optimisation
There are several constraints that have to be observed when ACE is used if
the best performance is to be achieved:
1. As usual the appropriate key set up subroutine must be called before any
of the above subroutines are used.
2. The AES contexts - aes_encryption_ctx and aes_decryption_ctx - used with
these subroutines MUST be 16 byte aligned. Failure to align AES contexts
will often cause memory alignment exceptions.
3. The buffers used for inputs, outputs and IVs do not need to be 16 byte
aligned but the speed that is achieved will be much higher if this can be
arranged. In a flat address space (as now typical in 32-bit systems) this
means that: (a) that the lower nibble of all buffer addresses must be
zero, and (b) the compiler used must arrange to load the data and stack
segments on 16 byte address boundaries. The Microsoft VC++ compiler can
align all variables in this way (see the example macros for doing this in
aes_via_ace.txt). However it seems that the GCC compiler will only do this
for static global variables but not for variables placed on the stack, that
is local variables.
4. The data length in bytes (len) in calls to the ECB and CBC subroutines
must be a multiple of the 16 byte block length. An error return will
occur if this is not so.
5. The data length in all calls to the CFB, OFB and CTR subroutines must also
be a multiple of 16 bytes if the VIA ACE engine is to be used. Otherwise
these lengths can be of any value but the subroutines will only proceed at
full speed for lengths that are multiples of 16 bytes. The CFB, OFB and
CTR subroutines are incremental, with subsequent calls continuing from
where previous calls finished. The subroutine aes_mode_reset() can be used
to restart a mode without a key change but is not needed after a new key is
entered. Such a reset is not needed when the data lengths in all individual
calls to the AES mode subroutines are multiples of 16 bytes.
6. Note that the AES context contains mode details so only one type of mode
can be run from a context at any one time. A reset is necessary if a new
mode is used without a new context or a new key.
D. Expected Speeds
The speeds that have been obtained using a 1.2 GHz VIA C3 processor with
this code are given below (note that since CTR mode is not available in
the VIA hardware it is not present in the aligned timing figures):

Issue 09/09/2006
The unsigned integer types defined here are of the form uint_<nn>t where
<nn> is the length of the type; for example, the unsigned 32-bit type is
'uint_32t'. These are NOT the same as the 'C99 integer types' that are
defined in the inttypes.h and stdint.h headers since attempts to use these
types have shown that support for them is still highly variable. However,
since the latter are of the form uint<nn>_t, a regular expression search
and replace (in VC++ search on 'uint_{:z}t' and replace with 'uint\1_t')
can be used to convert the types used here to the C99 standard types.

Issue Date: 01/08/2005
This is a byte oriented version of SHA2 that operates on arrays of bytes
stored in memory. This code implements sha256, sha384 and sha512 but the
latter two functions rely on efficient 64-bit integer operations that
may not be very efficient on 32-bit machines
The sha256 functions use a type 'sha256_ctx' to hold details of the
current hash state and uses the following three calls:
void sha256_begin(sha256_ctx ctx[1])
void sha256_hash(const unsigned char data[],
unsigned long len, sha256_ctx ctx[1])
void sha_end1(unsigned char hval[], sha256_ctx ctx[1])
The first subroutine initialises a hash computation by setting up the
context in the sha256_ctx context. The second subroutine hashes 8-bit
bytes from array data[] into the hash state withinh sha256_ctx context,
the number of bytes to be hashed being given by the the unsigned long
integer len. The third subroutine completes the hash calculation and
places the resulting digest value in the array of 8-bit bytes hval[].
The sha384 and sha512 functions are similar and use the interfaces:
void sha384_begin(sha384_ctx ctx[1]);
void sha384_hash(const unsigned char data[],
unsigned long len, sha384_ctx ctx[1]);
void sha384_end(unsigned char hval[], sha384_ctx ctx[1]);
void sha512_begin(sha512_ctx ctx[1]);
void sha512_hash(const unsigned char data[],
unsigned long len, sha512_ctx ctx[1]);
void sha512_end(unsigned char hval[], sha512_ctx ctx[1]);
In addition there is a function sha2 that can be used to call all these
functions using a call with a hash length parameter as follows:
int sha2_begin(unsigned long len, sha2_ctx ctx[1]);
void sha2_hash(const unsigned char data[],
unsigned long len, sha2_ctx ctx[1]);
void sha2_end(unsigned char hval[], sha2_ctx ctx[1]);
My thanks to Erik Andersen <andersen@codepoet.org> for testing this code
on big-endian systems and for his assistance with corrections

Issue Date: 01/08/2005
This is a bit oriented version of SHA2 that operates on arrays of bytes
stored in memory. This code implements sha256, sha384 and sha512 but the
latter two functions rely on efficient 64-bit integer operations that
may not be very efficient on 32-bit machines
The sha256 functions use a type 'sha256_ctx' to hold details of the
current hash state and uses the following three calls:
void sha256_begin(sha256_ctx ctx[1])
void sha256_hash(const unsigned char data[],
unsigned long len, sha256_ctx ctx[1])
void sha_end1(unsigned char hval[], sha256_ctx ctx[1])
The first subroutine initialises a hash computation by setting up the
context in the sha256_ctx context. The second subroutine hashes 8-bit
bytes from array data[] into the hash state withinh sha256_ctx context,
the number of bytes to be hashed being given by the the unsigned long
integer len. The third subroutine completes the hash calculation and
places the resulting digest value in the array of 8-bit bytes hval[].
The sha384 and sha512 functions are similar and use the interfaces:
void sha384_begin(sha384_ctx ctx[1]);
void sha384_hash(const unsigned char data[],
unsigned long len, sha384_ctx ctx[1]);
void sha384_end(unsigned char hval[], sha384_ctx ctx[1]);
void sha512_begin(sha512_ctx ctx[1]);
void sha512_hash(const unsigned char data[],
unsigned long len, sha512_ctx ctx[1]);
void sha512_end(unsigned char hval[], sha512_ctx ctx[1]);
In addition there is a function sha2 that can be used to call all these
functions using a call with a hash length parameter as follows:
int sha2_begin(unsigned long len, sha2_ctx ctx[1]);
void sha2_hash(const unsigned char data[],
unsigned long len, sha2_ctx ctx[1]);
void sha2_end(unsigned char hval[], sha2_ctx ctx[1]);

on big-endian systems and for his assistance with corrections

/*
* Example code for a decoder and encoder of "hash strings", with Argon2
* parameters.
*
* This code comprises three sections:
*
* -- The first section contains generic Base64 encoding and decoding
* functions. It is conceptually applicable to any hash function
* implementation that uses Base64 to encode and decode parameters,
* salts and outputs. It could be made into a library, provided that
* the relevant functions are made public (non-static) and be given
* reasonable names to avoid collisions with other functions.
*
* -- The second section is specific to Argon2. It encodes and decodes
* the parameters, salts and outputs. It does not compute the hash
* itself.
*
* The code was originally written by Thomas Pornin <pornin@bolet.org>,
* to whom comments and remarks may be sent. It is released under what
* should amount to Public Domain or its closest equivalent; the
* following mantra is supposed to incarnate that fact with all the
* proper legal rituals:
