CTR mode doesn't need separate encrypt and decrypt method. Encryption key can be set once. OpenSSL's AES_ctr128_encrypt takes care of most of the work, so the code can be simplified. Also we really need vector test.

I can get the encryption to work, but I can't figure out how to make it decrypt. 12 Dec 2017 Most often the CTR mode is combined with the AES block cipher which acts on 128-bits blocks.
