FFI bindings to OpenSSL available

Hi, I've just made the first version of my OpenSSL bindings available under: http://cryp.to/hopenssl/ Currently, the library contains only one module, Digest.hs, which provides a convenient Haskell interface to the message digest algorithms found in OpenSSL "crypto" library. (MD2, MD5, SHA, SHA1, DSS, DSS1, MDC2, and RIPEMD160.) A similar API to the symmetric cipher algorithms is expected to follow shortly. Patches, additions, and general feedback is -- as always -- highly welcome. Peter
