 A multi-purpose Cryptography library in Java. Working on it day by day, slowly. Someday this will be complete, today is not that day.
 To be clear, this is **NOT** mean't to be a replacement/alternative to BouncyCastle. Instead, it is meant to include what BouncyCastle does not have. No code was taken from OpenSSL or BouncyCastle for that reason.
