Dear Haskellers:

After hundreds of days working. I'm happy to announce that the very first version of [Z-Botan](http://hackage.haskell.org/package/Z-Botan) is published, It's a new crypto lib built around the versatile [botan]( http://botan.randombit.net/) C++ crypto lib. Currently, all crypto stuff exported by Botan FFI is implemented, i.e.:

* Random number generators. * Block Cipher and symmetric cipher. * Hash. * MAC. * Key derivation functions. * Password hash. * Constant time multiple precision integers. * Public key creation, import and export. * Public key encryption/decryption * Diffie-Hellman key exchange. * Signature generation & signature verification. * X.509 certificates & X.509 certificate revocation lists. * One time password. * AES Key Wrapping * Format Preserving Encryption.

We will continue to polish this work, e.g. build TLS upon it. If you have any crypto usage, please give it a try. as usual, we wish you happy hacking!
