WebSHA-3: a Secure Hash Algorithm The MD5 cryptographic hash function was published in April 1992: This document describes the MD5 message-digest algorithm. The algorithm takes as input a message of arbitrary length and produces as output a 128-bit "fingerprint" or "message digest" of the input. WebCRYPTREC was initially an abbreviation of Cryptography Research and Evaluation Committee, which was set up in 2000 by METI (Ministry of Economy, Trade and Industry, Japan) for the purpose of evaluating cryptographic techniques to assure their security for e-Government applications.

WebSHA-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. WebAlgorithms like MD5, SHA-1 and most of SHA-2 that are based on the Merkle–Damgård construction are susceptible to this kind of attack. Truncated versions of SHA-2, including SHA-384 and SHA-512/256 are not susceptible, nor is the SHA-3 algorithm. HMAC also uses a different construction and so is not vulnerable to length extension attacks. WebOct 15, 2024 · In addition, 128 bit RC4 and SHA-1 are listed on "Monitored Ciphers List". These are unsafe and only permitted to remain compatible with old systems.
