OpenCL

OpenCL aims to be a portable, easy to use, and efficient C++ cryto
library. It currently supports the following algorithms: 


*	Block Ciphers: Blowfish, CAST256, CAST5, CS-Cipher, DES, GOST,
        IDEA, Luby-Rackoff, MISTY1, RC2, RC5, RC6, Rijndael, SAFER-SK128,
        Serpent, SHARK, Skipjack, Square, TEA, Threeway, Twofish, XTEA 
*	Stream Ciphers: ARC4, ISAAC, SEAL 
*	Hash Functions: HAVAL, MD2, MD4, MD5, RIPE-MD128, RIPE-MD160,
        SHA-1, SHA2-256, SHA2-512, Tiger 
*	MACs: EMAC, HMAC, MD5MAC 
*	Misc: Adler32, CRC24, CRC32, Randpool, X9.17 RNG 
*	Cipher Modes: CBC w/ Padding, CFB, OFB, Counter 

It is distributed under the BSD license.

Portability

One of the main goals of OpenCL is high portability. It works on big and
little endian machines without any changes to the code (ie, no compile
time macros), and never assumes anything about pointer alignment. It uses
ISO C++ (the only extension required is that 64-bit integers must be
supported, which is the case on essentially every modern compiler, even
those running on 32-bit systems), and avoids areas where recent changes
may restrict portability (use of sstream and the specific semantics of
auto_ptr, for example). The current release has been tested on the
following systems: 

OS 	CPU TYPE 	 Compiler(s) 
Linux 	x86 	         egcs 1.1.2 / gcc 3.0 (20010327) / KAI C++ 3.4 g 
Linux 	Alpha/PPC/SPARC  gcc 2.95.2 
Tru64 	Alpha 	         Compaq C++ 6.2 [1] 
Solaris SPARC            gcc 2.95.2 
IRIX 	MIPS 	         MIPSpro C++ 7.2.1.1m [1] 

[1] Patch (see bad_lib.dif)

It is known that Visual C++ 6.0 SP3 has several bugs which prevent
compilation (presumably all earlier versions are also affected). However,
Visual C++ is widely enough used that I'll be attempting to make a patch. 

Shared libraries are probably not going to work except on ELF based
systems - fortunately, that includes most modern Unices (Tru64 5.0, while
not being ELF-based, has decent shared library support so you're OK
there).
