|An introduction to cryptography, in particular affine enciphering applied to the alphabet, focusing on the use of linear algebra. Includes a primer on bases and modulus algebra and extensions for deciphering an affine enciphered message, using keys to get the entries of matrices A and B, cracking a code that was encrypted using affine enciphering, and using frequency analysis to crack a code. Includes a list of other links and a bibliography.|
