Cryptography is coding messages, usually by using a cypher.
If you build a message and "translate it" into a code and only use that code once, it should be "secure" (meaning no one can "crack" the code).
The more you use a code (over time or in terms of the numbers of messages), the easier it is to crack.
The computer was originally developed to crack codes, by the way. It has been warped into being a typewriter, calculator, accounting and graphics tool.

Cryptography, is one essential aspect for secure communication...
Cryptography is the science of writing in secret code and is an ancient art; the first documented use of cryptography in writing dates back to circa 1900 B.C. when an Egyptian scribe used non-standard hieroglyphs in an inscription.
It is no surprise, then, that new forms of cryptography came soon after the widespread development of computer communications. In data and telecommunications, cryptography is necessary when communicating over any untrusted medium, which includes just about any network, particularly the Internet.
