Steganography : A technique for concealing information within other information.
You clicked on the image of the Bull, and if you did so because you are interested in steganography, it is not possible to use steganography with a black and white image.
There is a file, stored using steganography, in the image below. You can recover the message using HIP , Hidden in Picture. The image is of Major General George O'Malley (1780 - 1843) who, as a captain, served under the Duke of Wellington at the Battle of Waterloo.
Encryption.
E-mail messages are like postcards - everyone through whose hands/systems they pass can read them.
Very few people seem to mind about that, presumably because so few messages are truly confidential.
It is possible to encrypt e-mails, but the minimal additional effort required before sending a message appears to deter most people from using encryption.
You can download my PGP Public Key from here; although as it is not on a secure key server, there is no guarantee that it has not been tampered with. You might prefer to <right-click> on the link and use < Save Link Target As ... >
If you want to test your encryption, send me an e-mail.
If it does not look like spam, and if I can decrypt it, I will respond.
I use Pegasus Mail with QDPGP and PGP.
Combining encryption and steganography, ie encrypting a piece of text and concealing it within an innocent image, is allegedly a good way of getting information past even the most vigilant of eavesdropping organisations.
