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 the
selected file and then 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 reverse of steganography.
file2key can also be used to encrypt and decrypt files.
RATIONALE
file2key cannot be configured. The idea behind this is
that if it required configuration you would run the risk
of losing all your keys if you lost your configuration.
This must not happen.
