Analysis of Criminal Codes and Ciphers

For as long as man has had the ability to communicate, secrecy has been sought. Over the centuries various methods of secret writing, or cryptography, have been developed for numerous purposes. The two major categories of cryptographic systems are ciphers and codes, both of which are used extensively by criminals to conceal clandestine records, conversations, and writings.

Cryptology is the scientific study of cryptography and includes cryptanalytics, which deals with methods of solving cryptographic systems. This article is an introduction to the variety of secret writing encountered in law enforcement and describes the role of FBI cryptanalysts in examining and deciphering these criminal codes and ciphers.
