sym-crypt 1.2.0

sym-crypt is a core encryption module for the symmetric encryption app (and a corresponding gem) "sym", and contains the main base serialization, encryption, encoding, compression routines. sym-crypt uses a symmetric 256-bit key with the AES-256-CBC cipher, which is the same cipher as the one used by the US Government. For encyption with a password sym-crypt uses AES-128-CBC cipher. The resulting data is zlib-compressed and base64-encoded. The keys are also base64 encoded for easy copying/pasting/etc.
