SHA-1 & SHA-2 Family Explained
Understand SHA-1's weakness and how SHA-256 and SHA-512 differ.
Welcome
SHA-1 and SHA-2 are the NSA-designed successors to MD5. SHA-1 is now retired. SHA-256 and SHA-512 remain the industry standard for most applications.
SHA-1 Overview
SHA-1 produces a 160-bit (20-byte) hash. Designed by NSA, published 1995. Example: SHA1('hello') = aaf4c61ddcc5e8a2dabede0f3b482cd9aea9434d
