In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption—a series of well-defined steps that can be followed as a procedure.

A variant of the Vigenère cipher, which uses numbers instead of letters to describe the sequence of shifts, is called a Gronsfeld cipher. Gronsfeld ciphers can be solved as well through the Vigenère tool.
