Below is a non-exhaustive overview of (secret) encryption algorithms that
have been developed by or for the US
National Security Agency (NSA)
and that are further described on this website.
These algorithms are generally classed as an NSA Type 1 or Type 2
algorithm and are intended for governmental and military use.

Secret NSA Type 1 high-speed block cipher algorithm, used in several
products, such as the
Fortezza Plus crypto card and the
Philips GCD-Φ cryptographic processor.
Frequency Hopping System used for ECCM.
Implemented in the Cypris crypto chip.
Narrow band voice encryption used for radio and telephone communication.
Used with products like AIM,
Cypris (SAVILLE I and II), Windster (SAVILLE I),
INDICTOR (SAVILLE I),
and Cougar radios.
Joint development of GCHQ (UK) and the NSA (US).
Block cipher algorithm used in products like
and the Palladium Secure Modem. It was also used in the so-called
Clipper Chip that was featured in products like the
ill-fated AT&T TSD-3600 telephone encryptor.
The Skipjack algorithm was declassified by the
NSA on 24 June 1998.
High-speed link encryption that uses so-called hairpin registers.
Used in products like
Generally used for Trunk Encryption Devices (TED).
