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 ...
Replacing SHA-1 is urgent where it is used for digital signatures. All major web browser vendors ceased acceptance of SHA-1 SSL certificates in 2017. [15] [9] [4] In February 2017, CWI Amsterdam and Google announced they had performed a collision attack against SHA-1, publishing two dissimilar PDF files which produced the same SHA-1 hash.
In February 2017, the first known successful SHA-1 collision attack in practice (termed "SHAttered") was recognized. Marc Stevens was first-credited in the subsequent paper [ 6 ] along with CWI Amsterdam colleague Pierre Karpman, and researchers Elie Bursztein, Ange Albertini, Yarik Markov, Alex Petit Bianco, Clement Baisse [ 7 ] from Google .

SHA-1: A 160-bit hash function which resembles the earlier MD5 algorithm. This was designed by the National Security Agency (NSA) to be part of the Digital Signature Algorithm . Cryptographic weaknesses were discovered in SHA-1, and the standard was no longer approved for most cryptographic uses after 2010.

Linux kernel, version 5.17 replaced SHA-1 with BLAKE2s for hashing the entropy pool in the random number generator. [21] Open Network for Digital Commerce, a Government of India initiative, uses BLAKE-512 to sign API requests. [22] checksum, a Windows file hashing program has Blake2s as one of its algorithms [23]
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.
