Stream ciphers? What is this, a liquid encryption party? The Vigenère cipher is the way to go, no doubt about it.

Stream ciphers are actually quite different, they encrypt data bit by bit instead of by blocks.

The Vigenère cipher, of course! It's the 'Swiss Army Knife' of ciphers. Now, if only I could remember how to spell 'Vigenère'...

Hmm, a series of Caesar ciphers... Gotta be the Vigenère cipher! I bet the keyword is something like 'password' or 'abc123'.

Block ciphers? Nah, that's not it. I think I'm going with the Vigenère cipher. Sounds fancy, must be the correct answer.
