About SHA-256

SHA-256 is part of the SHA-2 family of cryptographic hash functions designed by the NSA. It produces a 256-bit hash value and is widely used in security applications including Bitcoin, TLS certificates, and password hashing.

  • No practical collision attacks have been found
  • Used by Bitcoin for proof-of-work and transaction hashing
  • Recommended for digital signatures and certificates
  • Preimage resistance: 2^256 operations required
  • Collision resistance: 2^128 operations required
