md5sum is a computer program that calculates and verifies 128-bit MD5 hashes, as described in RFC 1321. The MD5 hash functions as a compact digital fingerprint of a ...
All the attacker needs to generate two colliding files is a template file with a 128-byte block of data, aligned on a 64-byte boundary, that can be changed freely by the collision-finding algorithm. An example MD5 collision, with the two messages differing in 6 bits, is:
This is especially true of cryptographic hash functions, which may be used to detect many data corruption errors and verify overall data integrity; if the computed checksum for the current data input matches the stored value of a previously computed checksum, there is a very high probability the data has not been accidentally altered or corrupted.
File verification is the process of using an algorithm for verifying the integrity of a computer file, usually by checksum.This can be done by comparing two files bit-by-bit, but requires two copies of the same file, and may miss systematic corruptions which might occur to both files.

shasum is a Perl program to calculate any of SHA-1, 224, 256, 384, 512 hashes. [7] It is part of the ActivePerl distribution. 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 ...
