A cipher, in the context of cryptography, is an algorithm used to transform a message into another string of symbols in order to hide its meaning from a third party.

A cipher operates by replacing each symbol in the original string with a word in some alphabet.

The specific nature of the replacement depends on the specifics of the cipher.
