The Data Encryption Standard, or DES, was originally approved in 1977 as a block cipher algorithm that provides good cryptographic protection. Computational power has increased dramatically since 1977. DES is no longer considered to be secure. Since May 2005, it is recommended that DES no longer be used [Cen19].

The Advanced Encryption Standard, or AES, the replacement for DES, is detailed in Section 5.2.
