What is SHA3-256 (FIPS 202)?

SHA3-256 (FIPS 202) (Secure Hash Algorithm 256-bit) is a cryptographic hash function that produces a 256-bit (32-byte) hash value, typically rendered as a 64-character hexadecimal number. It is part of the SHA-3 family of hash functions standardized by NIST (FIPS 202).

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 (some systems use SHA3-256 (FIPS 202))
  • Password storage (with proper salting)
  • File integrity verification
  • Proof of work algorithms
