Crypto++ 2.0 has just been released. Please see the attached readme file for a description of Crypto++ and what's new in version 2.0. More details and download instructions can be found on my homepage at http://www.eskimo.com/~weidai. Wei Dai Crypto++: a C++ Class Library of Cryptographic Primitives Version 2.0 2/19/1996 This library includes: MD5, MD5-MAC, SHA, HAVAL, DES, IDEA, WAKE, 3-WAY, TEA, SAFER, Blowfish, Diamond2, Diamond2 Lite, Sapphire, Luby-Rackoff, MDC, various modes (CFB, CBC, OFB, counter), DH, DSA, ElGamal, LUC, Rabin, BlumGoldwasser, elliptic curve cryptosystems, BBS, gzip compression, Shamir's secret sharing scheme, Rabin's information dispersal scheme, and zero-knowledge prover and verifier for graph isomorphism. There are also various miscellanous modules such as base 64 coding and 32-bit CRC. RSA and RC5 are noticeably absent. I am still talking to RSA DSI about adding them back into Crypto++. I hope version 2.1 will include them. Crypto++ has been compiled and tested with Borland C++ 4.5, MSVC 4.0, and G++ 2.7.2 on MS-DOS, Windows NT, and a variety of Unix machines. You are welcome to use it for any purpose without paying me, but see license.txt for the fine print. Some short instructions to compile this library: (you probably need to modify this to suit your environment) -- if want to use this library with RSAREF, then 1. get a copy of RSAREF 2. untar or unzip it into a directory below this one 3. type "gcc -c -I. *.c" (in the rsaref/source directory) to compile RSAREF 4. edit config.h (make sure to #define USE_RSAREF) 5. type "g++ -c -Irsaref/source -I. *.cpp" to compile this library 6. type "g++ *.o rsaref/source/*.o -lstdc++ -lm" to link the test driver 7. type "a.out" to run the test driver -- if you DON'T want to use this library with RSAREF, then 1. edit config.h 2. type "g++ -c *.cpp" to compile this library 3. type "g++ *.o -lstdc++ -lm" to link the test driver 4. type "a.out" to run the test driver Finally, a note on object ownership: If a constructor for A takes a pointer to an object B (except primitive types such as int and char), then A owns B and will delete B at A's destruction. If a constructor for A takes a reference to an object B, then the caller retains ownership of B and should not destroy it until A no longer needs it. Good luck, and feel free to e-mail me at weidai@eskimo.com if you have any problems. Also, check http://www.eskimo.com/~weidai/cryptlib.html for updates and new versions. Wei Dai History 1.0 - First public release. Withdrawn at the request of RSA DSI. - Has a big bug in the RSA key generation code. 1.1 - Removed RSA, RC4, RC5 - Disabled calls to RSAREF's non-public functions - Minor bugs fixed 2.0 - a completely new, faster multiprecision integer class - added MD5-MAC, HAVAL, 3-WAY, TEA, SAFER, LUC, Rabin, BlumGoldwasser, Elliptic Curve algorithms - added the Lucas strong probable primality test - ElGamal encryption and signature schemes modified to avoid weaknesses - Diamond changed to Diamond2 because of key schedule weakness - fixed bug in WAKE key setup - SHS class renamed to SHA - lots of miscellaneous optimizations
