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 ...
Collisions against the full SHA-1 algorithm can be produced using the shattered attack and the hash function should be considered broken. SHA-1 produces a hash digest of 160 bits (20 bytes). Documents may refer to SHA-1 as just "SHA", even though this may conflict with the other Secure Hash Algorithms such as SHA-0, SHA-2, and SHA-3.
In many applications, the range of hash values may be different for each run of the program or may change along the same run (for instance, when a hash table needs to be expanded). In those situations, one needs a hash function which takes two parameters—the input data z , and the number n of allowed hash values.

Compute a cryptographic hash (using the SHA-1 and SHA-256 functions, respectively). ES:rSI points to data to compute a hash for, ES:rDI points to a message digest and rCX specifies the number of bytes. rAX should be set to 0 at the start of a calculation.

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.
