newtype Stream a

A Cipher with pseudorandom keys as long as the plaintext. Since Haskell is lazy, our keys here are actually of infinite length.

If for whatever reason a key of finite length is given to encrypt, the ciphertext is cutoff to match the key length. Example:

>>> encrypt [1,2,3] "ABCDEF" ^. stream
"BDF"
