SHA-2 - Wikipedia The algorithms are collectively known as SHA-2, named after their digest lengths (in bits): SHA-256, SHA-384, and SHA-512 The algorithms were first published in 2001 in the draft FIPS PUB 180-2, at which time public review and comments were accepted
SHA-1 - Wikipedia SHA-1 and SHA-2 are the hash algorithms required by law for use in certain U S government applications, including use within other cryptographic algorithms and protocols, for the protection of sensitive unclassified information
Hash Functions | CSRC SHA-2 family of hash algorithms: SHA-224, SHA-256, SHA-384, SHA-512, SHA-512 224, and SHA-512 256 NIST deprecated the use of SHA-1 in 2011 and disallowed its use for digital signatures at the end of 2013, based on both the Wang et al attack and the potential for brute-force attack
SHA Encryption Explained: SHA-1 vs. SHA-2 vs. SHA-3 Learn about SHA (Secure Hash Algorithms) encryption, its types (SHA-1, SHA-2, SHA-3), and how they secure data Understand why SHA-256 is widely used and how to protect your data
