Haha, I bet the answer is 'D' just to mess with us. RSA is always the answer, right?

You guys are overthinking this. It's clearly a stream cipher, just like the question says.

Nah, that sounds more like a stream cipher to me. Those use a fixed key and encrypt the message character by character.

I agree, it does sound like a stream cipher. It encrypts each letter individually with a fixed key.

Hmm, this one's tricky. I think it's a block cipher, since it mentions encrypting each letter one at a time.

I'm not sure, but I think Block cipher could also work since it encrypts one block of data at a time.
