About Hash Functions

Hash functions convert data of arbitrary size into fixed-size values. They are used for data integrity verification, password storage, and fingerprinting data.

  • MD5: 128-bit hash (no longer secure for cryptographic purposes)
  • SHA-1: 160-bit hash (deprecated for security applications)
  • SHA-256: 256-bit hash (widely used and secure)
  • SHA-512: 512-bit hash (provides higher security margin)
