About SHA-256

SHA-256 (Secure Hash Algorithm 256-bit) is a cryptographic hash function designed by the NSA and published by NIST in 2001.

It produces a 256-bit (32-byte) hash value, typically rendered as a 64-character hexadecimal string. SHA-256 is widely used in security applications and protocols, including TLS, SSL, PGP, SSH, and Bitcoin.

Unlike MD5, SHA-256 is considered cryptographically secure and is recommended for security-sensitive applications.

Common Use Cases

  • Password hashing and verification
  • Digital signatures and certificates
  • Blockchain and cryptocurrency
  • File integrity verification
  • Data deduplication
  • Proof-of-work systems
