Cryptographic Algorithms

Control

FIPS- approved or NIST-recommended cryptographic algorithms shall be used whenever cryptographic services are required. These approved algorithms have received an intensive security analysis prior to their approval and continue to be examined to determine that the algorithms provide adequate security. Most cryptographic algorithms require cryptographic keys or other keying material. In some cases, an algorithm may be strengthened by the use of larger keys. This Recommendation advises the users of cryptographic mechanisms on the appropriate choices of algorithms and key sizes. This section describes the approved cryptographic algorithms that provide security services, such as confidentiality, integrity authentication, and source authentication.
