Codes and Ciphers
In the opinion of one of the greatest cryptologists of all time, William F. Friedman, the invention of writing formed the true beginning of civilization. But not too long after writing really got established, various people found a need for writing that could only be read by an intended recipient, but not anyone else.

Codes, Ciphers, & Codebreaking
Codes, ciphers, and codebreaking have been around for millennia, with the survival of nations sometimes hanging on the security of codes and ciphers. With modern computer networking, they have become important in day-to-day life. This document provides a technical and historical introduction to codes, ciphers, and codebreaking.

Secret Language
When you were a kid, did you have a "Captain Midnight" decoder ring? With it, you could send messages to friends that no one else could read. Or perhaps you remember using special symbols to write notes to your "squeeze" in class.

Social Intellect Reformation
The Brasseur Universal Code is a system of symbolic logic characters. Each of the symbolic logic characters has an inherent quality that allows the character to project a resonant harmonic energy field in base- two binary.

CryptoKids™ America's Future Codemakers & Codebreakers - NSA
What�s cryptology? Cryptology is making and breaking codes. It�s so cool. We make codes so we can send secret messages to our friends. And we try to figure out what other people are writing about by breaking their codes.

Secret Codes in Slave Quilts - National Security Agency
Modern codes frequently involve number code groups and mathematical algorithms. Some older codes used alternate words, such as the Native American Code Talkers� system. It is believed that in the early and mid-1800s, slaves in America�s southern states developed a code that involved quilt patterns.
