Let alone something that ALSO goes from JPEG to PDF by applying 3DES.&lt;p&gt;I presume there is some algorithm based on the nature of ciphers themselves?</text><parent_chain></parent_chain></comment><story><title>A JPEG that becomes a PNG after AES encryption and a PDF after 3DES decryption</title><url>https://code.google.com/p/corkami/source/detail?r=1906</url></story>
