JBO Zeta Cipher Description

Zeta Cipher is an application designed to secure text and messages using a modern implementation of neo-classical cryptographic methods. What all ciphers have in common is that ultimately, they are breakable. The issue is the amount of time it would take to break them and whether such time would be well spent. Some modern methods of encryption rely on large numbers which (so far) cannot be factored for security. Most traditional ciphers have a finite number of solutions consider a cipher system which uses an alphanumeric key (any sequence of permitted characters and of any length) to perform alphabetic substitution against a random table of cipher characters, and a numeric key which allows the user to select any of one thousand variants of the cipher table, along with irregular columnar transposition based on a key which is automatically calculated by the program, and you have the basis of the Zeta Cipher. The program provides tabbed pages into which plain text, or cipher text, may be typed or loaded from suitable text files. Once the keys have been entered, the user may encrypt or decrypt the desired text. With one kilobyte of text, frequency is generally below 5% for all characters, and the user may select keys to obtain frequencies much lower than that. It is possible to use randomly generated keys equal in length to the plain text, thus enabling Zeta to operate as a One Time Pad cipher. Even with shorter and more user-friendly keys, patterns in cipher text are not helpful to anyone attempting to analyze the cipher. When decrypting a piece of cipher text, even though the keys are not encrypted into the text, the Zeta program is aware of whether the result is the correct plain text or not. If the incorrect keys are used, or if the cipher text is not an example of Zeta encryption, then output to the plain text page will be the message "Incorrect keys or source data".
