Same key, same plaintext, two different ciphertexts.

 Both. I wanted each encryption using the same key and plaintext to create radically different ciphertexts.
 Also, I wanted it to be bit sensitive. If a single bit of ciphertext is altered it will decrypt to random junk.
 My HMAC Cipher experiment does both.
 I think those are interesting things.

You can play around with this on my site. Try altering the ciphertext in anyway, and hit decrypt. The plaintext will be random garbage. It would help if my site used a real TRNG, but oh well for now.
