LuaCrypto provides a Lua frontend to the OpenSSL cryptographic library. The OpenSSL features that are currently exposed are digests (MD5, SHA-1, HMAC, and more) and crypto-grade random number generators. LuaCrypto also supports encryption and decryption, signing and verifying, sealing and opening using the OpenSSL EVP API. Please see docs at doc/us/index.html or http://luacrypto.luaforge.net/.
