2. Secure Hash Algorithms - Wikipedia

   en.wikipedia.org/wiki/Secure_Hash_Algorithms

   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.

3. BLAKE (hash function) - Wikipedia

   en.wikipedia.org/wiki/BLAKE_(hash_function)

   BLAKE was submitted to the NIST hash function competition by Jean-Philippe Aumasson, Luca Henzen, Willi Meier, and Raphael C.-W. Phan. In 2008, there were 51 entries. BLAKE made it to the final round consisting of five candidates but lost to Keccak in 2012, which was selected for the SHA-3 algorithm.

5. SHA-2 - Wikipedia

   en.wikipedia.org/wiki/SHA-2

   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.

6. SM3 (hash function) - Wikipedia

   ShangMi 3 (SM3) is a cryptographic hash function, standardised for use in commercial cryptography in China. [1] It was published by the National Cryptography Administration (Chinese: 国家密码管理局) on 2010-12-17 [2] [3] as "GM/T 0004-2012: SM3 cryptographic hash algorithm".

7. md5sum - Wikipedia

   en.wikipedia.org/wiki/Md5sum

   md5sum is specific to systems that use GNU coreutils or a clone such as BusyBox.On FreeBSD and OpenBSD the utilities are called md5, sha1, sha256, and sha512.These versions offer slightly different options and features.
