Sean Parkinson 59a17dd598 Unit testing: Add Monte Carlo testing to ciphers 
Monte Carlo testing is randomized test data.
These new tests have random keys, IVs, nonce, etc and random data to
encrypt.
100 sets of random test data are encrypted and decrypted with a check to
ensure the input to encrypt is the same as the output of decrypt.
Tags are generated and checked in the calls to encrypt and decrypt.
