Typically distributed alongside sha1sum are sha224sum, sha256sum, sha384sum and sha512sum, which use a specific SHA-2 hash function and b2sum, [1] which uses the BLAKE2 cryptographic hash function. The SHA-1 variants are proven vulnerable to collision attacks , and users should instead use, for example, a SHA-2 variant such as sha256sum or the ...
The simplest checksum algorithm is the so-called longitudinal parity check, which breaks the data into "words" with a fixed number n of bits, and then computes the bitwise exclusive or (XOR) of all those words. The result is appended to the message as an extra word.

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.
SHA-0: A retronym applied to the original version of the 160-bit hash function published in 1993 under the name "SHA". It was withdrawn shortly after publication due to an undisclosed "significant flaw" and replaced by the slightly revised version SHA-1. SHA-1: A 160-bit hash function which resembles the earlier MD5 algorithm.

On Unix-like systems, similar functionality can be often obtained by combining find with hashing utilities such as md5sum, sha256sum or tthsum. md5deep exists for Windows and most Unix-based systems, including OS X. It is present in OS X's Fink, Homebrew and MacPorts projects. Binary packages exist for most free Unix systems.
