monoalphabetic


monoalphabetic, a MATLAB code which applies a monoalphabetic substitution cipher to a string of text.

A code is specified by listing 26 symbols that are to be used to replace the characters "A" through "Z" in the text. (Note that, before encryption, the string is capitalized.) The same code can be used to reverse the encryption process.
