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.

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)). In cryptography, SHA-1 (Secure Hash Algorithm 1) is a hash function which takes an input and produces a 160-bit (20-byte) hash value known as a message digest – typically rendered as 40 hexadecimal digits. It was designed by the United States National Security Agency, and is a U.S. Federal Information Processing Standard. The algorithm has been cryptographically broken but is still widely used.
