WebJul 19, 2013 · 3. @trm42 Actually it does work. It compares the incoming password X against the db password Y using hash (X)==Y, since it assumes that Y is already hashed correctly. What we are doing, is setting X to match Y, then hashing Y so that it will match X. The actual test being run then, is hash (sha1 (X))==hash (sha1 (Y)). 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. philosophyball https://lutzlandsurveying.com

WebWe would like to show you a description here but the site won’t allow us. WebSo, my recommendation of bcrypt stems from the assumptions 1) that a Blowfish has had a similar level of scrutiny as the SHA-2 family of hash functions, and 2) that cryptanalytic methods for ciphers are better developed than those for hash functions.
