SHA-2: A family of two similar hash functions, with different block sizes, known as SHA-256 and SHA-512. They differ in the word size; SHA-256 uses 32-bit words where SHA-512 uses 64-bit words. There are also truncated versions of each standard, known as SHA-224, SHA-384, SHA-512/224 and SHA-512/256. These were also designed by the NSA.
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.
SHACAL-2 is a 256-bit block cipher based upon the larger hash function SHA-256. Both SHACAL-1 and SHACAL-2 were selected for the second phase of the NESSIE project. However, in 2003, SHACAL-1 was not recommended for the NESSIE portfolio because of concerns about its key schedule, while SHACAL-2 was finally selected as one of the 17 NESSIE ...
sha3sum is a similarly named program that calculates SHA-3, HAKE, RawSHAKE, and Keccak functions. [8] The <hash>sum naming convention is also used by the BLAKE team with b2sum and b3sum, by the program tthsum, and many others. On FreeBSD and OpenBSD, the utilities are called md5, sha1, sha256, and sha512. These versions offer slightly different ...
The cryptographic hash functions available for use in VeraCrypt are BLAKE2s-256, SHA-256, SHA-512, Streebog and Whirlpool. [11] VeraCrypt used to have support for RIPEMD-160 but it has since been removed in version 1.26. [12] VeraCrypt's block cipher mode of operation is XTS. [13]
