About SHA-3 Hash

SHA-3 (Secure Hash Algorithm 3) is the latest member of the Secure Hash Algorithm family of standards, released by NIST in 2015. Unlike SHA-1 and SHA-2, which are based on the MD5-like structure, SHA-3 uses the sponge construction based on the Keccak permutation.

  • • Immune to length-extension attacks
  • • High security margin
  • • Efficient in hardware implementations
  • • Versatile (supports XOFs like SHAKE)

Usage Examples

  • • Digital signatures
  • • Password hashing
  • • Message authentication (HMAC)
  • • Data integrity verification
