<cryptography> An encryption algorithm created by the NSA
(National Security Agency) which encrypts 64-bit blocks of
data with an 80-bit key. It is used in the Clipper chip, a
VLSI device with an ARM processor core, which is intended
to perform cryptographic operations while allowing the
security agencies listen in.
There are (apparently) two agencies, both of whom have to
agree that there is a valid reason to decode a message. Don't
laugh, they are serious.
