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 ...
HashCheck Shell Extension - SFV, MD4, MD5, SHA-1 (Multi-Language) Total Commander - supports creation and verification of SFV files; hkSFV - supports creation and verification of SFV files (crashes on massive SFV files check) DySFV - Open Source (free) application for large files; ilSFV - free and open-source SFV, MD5 and SHA-1 file ...
The particular hash algorithm used is often indicated by the file extension of the checksum file. The ".sha1" file extension indicates a checksum file containing 160-bit SHA-1 hashes in sha1sum format. The ".md5" file extension, or a file named "MD5SUMS", indicates a checksum file containing 128-bit MD5 hashes in md5sum format.
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.
The following tables compare general and technical information for a number of cryptographic hash functions. See the individual functions' articles for further information. This article is not all-inclusive or necessarily up-to-date. An overview of hash function security/cryptanalysis can be found at hash function security summary.

This tool saves an image of a hard disk in one file or in segments that may be later on reconstructed. It calculates MD5 and SHA1 hash values and can verify the integrity of the data imaged is consistent with the created forensic image. The forensic image can be saved in several formats, including DD/raw, E01, and AD1.
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.
