Using Block Ciphers

- Summary

Abstract

A block cipher on its own is rather limited.It takes a b-bit string and outputs a b-bit string under the action of a secret key. But what happens when the message we wish to encrypt is 37 bits long and is too small to fill an entire block? What happens if the message is too long for a single block?
