Giova X Cipher is an application especially designed to secure text and messages using classical cryptographic methods. What all ciphers (except a One Time Pad) 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 cannot be factored for security. Most traditional ciphers have a finite number of solutions consider a cipher system which uses an alphabetic key (any sequence of letters and of any length) to perform polyalphabetical substitution against a random table of cipher character pairs, and a numeric key which allows the user to select any one of 650 variants of the cipher table, and you have the basis of the Giova X 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. When text is present on the cipher text page, it is possible to generate a bar graph showing the frequency analysis of the cipher text.

For amounts of text of one kilobyte or more, the distribution is usually below 6% for all characters (assuming a key which is not very repetitious). It is possible to use randomly generated keys equal in length to the plain text, thus enabling Giova X to operate as a One Time Pad cipher. Even with shorter and more user-friendly keys, patterns in ciphertext 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 Giova X 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 Giova encryption, then output to the plain text page will be the message "Incorrect keys or source data".
