SHA-1: A 160-bit hash function which resembles the earlier MD5 algorithm. This was designed by the National Security Agency (NSA) to be part of the Digital Signature Algorithm. Cryptographic weaknesses were discovered in SHA-1, and the standard was no longer approved for most cryptographic uses after 2010.
NSA cryptography. The vast majority of the National Security Agency 's work on encryption is classified, but from time to time NSA participates in standards processes or otherwise publishes information about its cryptographic algorithms. The NSA has categorized encryption items into four product types, and algorithms into two suites.
Advanced Encryption Standard (AES): an encryption algorithm, selected by NIST after a public competition. In 2003, NSA certified AES for Type 1 use in some NSA-approved systems. Secure Hash Algorithm: a widely used family of hash algorithms developed by NSA based on earlier designs by Ron Rivest. Digital Signature Algorithm; Data Encryption ...
NSA Suite B Cryptography. NSA Suite B Cryptography was a set of cryptographic algorithms promulgated by the National Security Agency as part of its Cryptographic Modernization Program. It was to serve as an interoperable cryptographic base for both unclassified information and most classified information. Suite B was announced on 16 February 2005.
Commercial National Security Algorithm Suite. The Commercial National Security Algorithm Suite (CNSA) is a set of cryptographic algorithms promulgated by the National Security Agency as a replacement for NSA Suite B Cryptography algorithms. It serves as the cryptographic base to protect US National Security Systems information up to the top ...
SHA-2 (Secure Hash Algorithm 2) is a set of cryptographic hash functions designed by the United States National Security Agency (NSA) and first published in 2001. [3][4] They are built using the Merkle–Damgård construction, from a one-way compression function itself built using the Davies–Meyer structure from a specialized block cipher.
FIPS 140-3. The Federal Information Processing Standard Publication 140-3 (FIPS PUB 140-3) [1][2] is a U.S. government computer security standard used to approve cryptographic modules. The title is Security Requirements for Cryptographic Modules. Initial publication was on March 22, 2019 and it supersedes FIPS 140-2.
The FIPS 140-2 standard is an information technology security approval program for cryptographic modules produced by private sector vendors who seek to have their products certified for use in government departments and regulated industries (such as financial and health-care institutions) that collect, store, transfer, share and disseminate ...
