A JPEG that becomes a PNG after AES encryption and a PDF after 3DES decryption
How in the hell does one discover that kind of thing? :) I don't really know much about crypto and symmetric ciphers in general, but aren't the odds of discovering something that converts from JPEG to PNG by applying AES extremely small? Let alone something that ALSO goes from JPEG to PDF by applying 3DES.<p>I presume there is some algorithm based on the nature of ciphers themselves?
