Currently, this module supports the block ciphers

	blowfish      - 16 byte key length, 8 byte block length
	blowfish160   - 16 byte key length, 16 byte block length
	twofish       - 16 byte key length, 16 byte block length
	3des          - 16 byte key length (hashed to 24 bytes), 8 byte block length

and the hash functions

	md5           - 20 byte result
	sha1          - 20 byte result
	ripem160      - 20 byte result
