About SHA256

SHA256 (Secure Hash Algorithm 256) is a member of the SHA-2 family of cryptographic hash functions. It produces a 256-bit hash value, typically expressed as a 64-character hexadecimal number.

SHA256 Characteristics

  • Output Size: 256 bits (32 bytes)
  • Hex Representation: 64 hexadecimal characters
  • Collision Resistance: Strong (no known collisions)
  • Preimage Resistance: Strong
  • Common Uses: Password hashing, digital signatures, blockchain, SSL/TLS certificates

Security Status

✅ SHA256 is considered cryptographically secure and is widely used in security applications. It is part of the SHA-2 family and is recommended by NIST for most cryptographic purposes.
