What is more deceiving is the purpose, which is unclear. If you want to send
images, why would you need to know the algorithm? Are you building a mail
client or encryption package for a mail client?
You can use PGP < http://www.pgpi.org/ > in your mail application or encrypt
just the file using PGP and then send an unencrypted E-mail message which
contains the file.
