Food for your TS-2068: A Private-Key Cryptosystem

The subject this month will be cryptography. Cryptography, as you all know, is the science of disguising information into unintelligible code that would be worthless to any would-be trespasser. The 2068 computer, because of its speed and ability to manipulate large character arrays, makes an excellent secret-coding machine. The program I will present below is a sophisticated “private-key” cryptographic system which is very easy to use, provides a high level of cryptographic protection, and is quite fast. The program allows you to encipher your confidential or sensitive messages by means of a personal password (which must be kept secret). Only by using the exact password can you, or anyone else, decipher or unlock coded messages into their original form.
