========

WjCryptLib
|

==========

||||
CryptLib is a collection of cryptographic functions written in C. Each
|
||||
WjCryptLib is a collection of cryptographic functions written in C. Each
|
||||
module is fully independent and generally requires only a single .c file
|
||||
and a a single .h file. AES-CTR does depend on the AES module, so in this
|
||||
case all four files are needed.
|
||||
|
||||
The functions are designed to be portable and have been tested on both
|
||||
a Little-Endian and a Big-Endian architecture
|
||||
a Little-Endian and a Big-Endian architecture. OpenMP is supported where
|
||||
parallelisation can occur.
|
||||
|
||||
The library and the demo programs can be built using CMake to generate
|
||||
a build setup for any system, including Visual Studio on Windows and
|
||||
Make or Ninja for Linux. Refer to cmake.org to get CMake.

Library
|
||||
-------
|
||||
|
||||
To use the library functions, only the following files are required,
|
||||
depending on what cryptographic functions are wanted.
|
||||
|
||||
* MD5 - (WjCryptLib_Md5.h, and WjCryptLib_Md5.c)
|

* SHA1 - (WjCryptLib_Sha1.h, and WjCryptLib_Sha1.c)

* AES - (WjCryptLib_Aes.h, and WjCryptLib_Aes.c)
|
||||
* AES-CTR - (WjCryptLib_AesCtr.h, and WjCryptLib_AesCtr.c, WjCryptLib_Aes.h,
|
||||
and WjCryptLib_Aes.c)
|
||||
* AES-OFB - (WjCryptLib_AesOfb.h, and WjCryptLib_AesOfb.c, WjCryptLib_Aes.h,

and WjCryptLib_Aes.c)

Version 2.3.0 - March 2018
|
||||
--------------------------
|
||||
|
||||
* Added AES-CBC module.
|
||||
* Added functions Md5Calculate, Sha1Calculate, Sha256Calculate, and
|
||||
Sha512Calculate to calculate a hash in one call.
|
||||
* Added function Rc4XorWithKey to encrypt/decrypt a buffer with RC4 in
|
||||
one call.
|
||||
* Bugfix: AesInitialise now returns -1 if invalid key size is provided.
|
||||
Previously it would return 0 despite what was documented.
|
||||
|
||||
Version 2.2.0 - January 2018
|
||||
----------------------------
|
||||
|
||||
* Added AES-OFB module.
|
||||
* File names have been changed to have the prefix `WjCryptLib_` rather
|
||||
than `CryptLib_`.
|
||||
* Removed compiled binaries from source tree.
|
||||
|
||||
Version 2.1.0 - December 2017
|
||||
-----------------------------
|
||||
|
||||
Changes:
|
||||
|
||||
* Changed implementation of AES to one which is almost 5 times as fast.
|
||||
The new implementation comes from LibTomCrypt. The newer implementation
|
||||
produces a larger binary size as a trade-off.
|
||||
* AES-CTR module now supports OpenMP and when compiled with OpenMP will
|
||||
run in parallel giving a much greater speed.
|
||||
* Changed interface for Initialisation functions for both AES and AES-CTR
|
||||
to be match RC4 (The context is first parameter not last)

// AES is a block cipher that operates on 128 bit blocks. Encryption an Decryption routines use an AesContext which

|
||||
// are not changed by the encrypting and decrypting functions. A context only needs to be initialised once for any

// given key and the context may be used by the encrypt/decrypt functions in simultaneous threads.
