The SHA-2 hash function is implemented in some widely used security applications and protocols, including TLS and SSL, PGP, SSH, S/MIME, and IPsec. SHA-256 is used for authenticating Debian software packages and in the DKIM message signing standard; SHA-512 is part of a system to authenticate archival … See more 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. They are built using the Merkle–Damgård construction, … See more With the publication of FIPS PUB 180-2, NIST added three additional hash functions in the SHA family. The algorithms are collectively known as SHA-2, named after their … See more Hash values of an empty string (i.e., a zero-length input text). Even a small change in the message will (with overwhelming probability) result in a different hash, due to the avalanche effect. For example, adding a period to the end of the following … See more In the table below, internal state means the "internal hash sum" after each compression of a data block. In the bitwise … See more For a hash function for which L is the number of bits in the message digest, finding a message that corresponds to a given message digest can always be done using a See more Pseudocode for the SHA-256 algorithm follows. Note the great increase in mixing between bits of the w[16..63] words compared to SHA-1. The computation of the ch and maj values can be optimized the same way as described for SHA-1 See more Below is a list of cryptography libraries that support SHA-2: • Botan • Bouncy Castle • Cryptlib • Crypto++ • Libgcrypt See more WebTable 522: Firefox cipher suites. * SHA1 algorithms are not supported on appliance certificates, but are allowed on external server or managed device certificates. Any such SHA1 appliance certificates must be recreated and re-imported before you attempt a …
