This manual presents the basic principles and techniques of cryptanalysts and their relation to cryptography. Cryptography concerns the various ways of protecting messages from being understood by anyone except those for whom the messages are intended. Cryptographers are the people who create and use codes and ciphers. Cryptanalytics is the art and science of solving unknown codes and ciphers. Cryptanalysts try to break the codes and ciphers created and used by cryptographers.

Cryptography is the stuff of spy novels and action comics. Kids once saved up
OvaltineTM labels and sent away for Captain Midnight’s Secret Decoder Ring.
Almost everyone has seen a television show ormovie involving a nondescript
suit-clad gentleman with a briefcase handcuffed to his wrist. The word
“espionage” conjures images of James Bond, car chases, and flying bullets.
And here you are, sitting in your office, faced with the rathermundane task of
sending a sales report to a coworker in such a way that no one else can read it.
