NAME
	file2key - generates a key from a file and a passphrase

SYNOPSIS
	file2key [file]

DESCRIPTION
	file2key uses Keccak[] to create a hash as big as a
	selected file and the prints the bitwise exclusive or
	of the hash and the file making a key file from any
	normal file and a passphrase.

	The idea is the reversed of steganography.

	file2key can also be used to encrypt and decrypt files.

RATIONALE
	file2key cannot be configured. The idea behind this is
	that you if it required configurations you run the risk
	of losing all your keys if you lose your configurations.
	This must not happen.
