About SHA-512
SHA-512 is part of the SHA-2 family designed by the NSA and published by NIST in 2001. It produces a 512-bit (64-byte) digest and operates on 64-bit words, making it exceptionally fast on modern 64-bit processors — often faster than SHA-256. SHA-512 is used in digital signatures, certificate chains, archival integrity verification, and in password hashing schemes like SHA-512/crypt. It offers a wide security margin with no known weaknesses.
