What is SHA2?

SHA2 (Secure Hash Algorithm 2) is a family of cryptographic hash functions designed by the NSA. The SHA2 family includes SHA-224, SHA-256, SHA-384, and SHA-512. SHA2 is widely used in security applications and is considered secure.

SHA2 variants

  • SHA-224: 224-bit hash (56 hex characters) - Good balance of security and length.
  • SHA-256: 256-bit hash (64 hex characters) - Most commonly used variant.
  • SHA-384: 384-bit hash (96 hex characters) - Higher security.
  • SHA-512: 512-bit hash (128 hex characters) - Maximum security.

SHA2 use cases

  • Password hashing: Secure password storage (with salt).
  • Digital signatures: Verify data authenticity and integrity.
  • Blockchain: Used in Bitcoin and other cryptocurrencies.
  • SSL/TLS: Certificate verification and secure communications.
  • Data integrity: Verify files and data haven't been modified.
