This led me to steganography, the technology of hiding information. There are stego programs for hiding messages in a variety of places. I hide messages in pictures, in sound files, even in other texts, then post the medium in a mutually agreed on place for my friend to pick up. Then I use PGP to encrypt it. I now have an image that is identical to the original to the eye, and is the same size and date as the original.
Replies come in a similar fashion.
I guess steganography is really about sending postcards that are truly private. If you find anything awry at this site, please contact the Web Tender .
