Hello,

I uploaded a crypto library to the vault http://boost-consulting.com/vault/index.php?action=downloadfile &filename=crypto_v01.zip&directory=& which provides some cryptographic primitives.

Message Digest algorithms: MD4, MD5, RIPEMD128, RIPEMD160, RIPEMD256, RIPEMD320, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512

Message Authentication Code: HMAC

Block Ciphers: Blowfish, Rijndael

Block Cipher Modes: Electronic Code Book Mode, Cipher Block Chaining Mode

Padding Modes : Zero padding, One and zeros padding

Stream Cipher: RC4

Example - construction of a blowfish cipher in CBC mode with zero padding:

typedef boost::crypto::block_cipher< boost::crypto::blowfish_cipher, boost::crypto::cbc_mode, boost::crypto::zero_padding

...

my_cipher;

The documentation is quite incomplete, no examples are provided. Please have a look at the test directory to see these things in action. The reason I'm posting this now is that I don't think I will have enough time in the near future to spend on this code. The code which exists now is good though, I still have some todos in my head but it's usable as it is.

This looks a most valuable library in the making - but needs a modest amount more work to be Boostable. Some more work on the docs - already in Quickbook format. I didn't spot test in using the Boost.test structure. And examples for the Cryptogrpahically challenged would make this much more widely useful. Would this be a good GSoC project for someone next year? Paul --- Paul A Bristow Prizet Farmhouse, Kendal, Cumbria UK LA8 8AB +44 1539561830 & SMS, Mobile +44 7714 330204 & SMS pbristow@hetp.u-net.com
