It is derived from SHA-1, with assorted changes intended to increase its security. It produces a 160-bit output. HAS-160 is used inMD4The MD4 (Message-Digest 4) algorithm is a cryptographic hash function developed by Ronald Rivest in 1990. The digest length is 128 bits. The algorithm has influenced later designs, such as the MD5, SHA-1 and RIPEMD algorithms. The security NT хешейAn NT Hash, sometimes referred to as an NTLM hash, is a method of storing passwords on Windows systems. It works by running MD4 on UTF-16LE encoded input. NTLM hashes are considered weak because they can be brute-forced very easily with modRIPEMDRIPEMD (RACE Integrity Primitives Evaluation Message Digest) is a family of cryptographic hash functions developed in Leuven, Belgium, by Hans Dobbertin, Antoon Bosselaers and Bart Preneel at the COSIC research group at the Katholieke UniveROR13Computes a ROR13 hash used in API hashing techniques.SHA1The SHA (Secure Hash Algorithm) hash functions were designed by the NSA. SHA-1 is the most established of the existing SHA hash functions and it is used in a variety of security applications and protocols. However, SHA-1's collision resistaSHA2The SHA-2 (Secure Hash Algorithm 2) hash functions were designed by the NSA. SHA-2 includes significant changes from its predecessor, SHA-1. The SHA-2 family consists of hash functions with digests (hash values) that are 224, 256, 384 or 51SHA3The SHA-3 (Secure Hash Algorithm 3) hash functions were released by NIST on August 5, 2015. Although part of the same series of standards, SHA-3 is internally quite different from the MD5-like structure of SHA-1 and SHA-2. SHA-3 is a subsetShakeShake is an Extendable Output Function (XOF) of the SHA-3 hash algorithm, part of the Keccak family, allowing for variable output length/size.SnefruSnefru is a cryptographic hash function invented by Ralph Merkle in 1990 while working at Xerox PARC.
