Unbreakable Code?

Currently considered unbreakable, a code encryption technique called "steganography" is used to bury a message in a digital image, audio, or video file. The sender uses a unique key to encode the file and then posts it somewhere on the Internet (e-Bay, discussion group, etc.). The receiver visits the site, downloads the file and uses a matching key to decode the message. The boys at NSA aren't too happy about this one.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a lady's voice announced "You've Got Mail" when a new message arrived...
