Definitions Words to know:. Here are some useful categories of ciphers. Note that a particular cipher may belong to more than one of these categories. Secret key a. Caesar Cipher A completely pathetic and insecure cipher by modern standards. Instead of simply adding a fixed offset to each character, you can precompute a substitution table by generating a random permutation of your alphabet. For example:. For techniques whose key is a permutation, one way to make the key easier to remember is to pick a phrase, lay out its unique letters, then fill in missing letters in order.
Each plaintext letter maps to one or more symbols in the ciphertext. The number of targets should be proportional to its frequency to defeat frequency analysis. If the key length can be determined, the cryptanalyst can do multiple frequency analyses one for each shift value in the key.

Methods for determining key length are the Kaisiski Method and the Friedman test. For binary data i. Modern auto-key ciphers generate the shift values with a random number generator. The key seeds the generator. Then you have a provably secure cipher called the one time pad. Your actual algorithm can use polyalphabetic substitution or even simple xoring the message with the key, as long as you meet the three criteria above.
The one-time pad can never be cracked. It is a perfect encryption scheme, from a mathematical perspective, anyway. This is an example of a polygraphic substitution cipher. It replaces pairs of characters. To encrypt, write out the plaintext without spaces or punctuation , sticking in an X between double letters and at the end if necessary to make the text have even length. Then for each pair of letters:.
