NSA algorithms
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. For a more complete overview, check out this page.

Backdoored NSA algorithms
  • PX-1000Cr
    In 1983, the NSA persuaded Dutch electronics giant Philips to replace the DES algorithm of the PX-1000 pocket telex, by an alternative NSA-developed algorithm that appeared stronger, but could in realty be broken with relative ease by the NSA.
Mathematical algorithms
  • AES
    Advanced Encryption Standard

  • DES
    Data Encryption Standard
