FCP takes a file, generates a random 2048 bit key and encrypts the file with
a RC4 stream cipher. The encrypted file is written to a new file along with
the decryption stub and key. When the output file is executed it decrypts and 
executes the encrypted file.

It's written in Delphi 6, enjoy the source code.
