What is SHA-512?

SHA-512 (Secure Hash Algorithm 512-bit) is a cryptographic hash function that produces a 512-bit (64-byte) hash value, typically rendered as a 128-character hexadecimal number. It is part of the SHA-2 family of hash functions designed by the NSA and published by NIST.

Key characteristics:

  • Deterministic: The same input always produces the same hash
  • Fast computation: Quick to compute for any given input
  • Avalanche effect: Small changes in input produce drastically different outputs
  • Irreversible: Computationally infeasible to reverse the hash to find the original input
  • Collision resistant: Very difficult to find two different inputs that produce the same hash

Common uses:

  • Digital signatures and certificates
  • Blockchain and cryptocurrency (Bitcoin uses SHA-256, but SHA-512 is used in other systems)
  • Password storage (with proper salting)
  • File integrity verification
  • Proof of work algorithms
