Hash Generator

Generate MD5, SHA-1, SHA-256, and SHA-512 cryptographic hashes

About Hash Functions

Hash functions are one-way cryptographic algorithms that convert any input into a fixed-size string of bytes. The same input always produces the same hash, but it's practically impossible to reverse the process.

Algorithms

  • MD5: 128-bit hash (32 hex characters). Fast but not secure for passwords.
  • SHA-1: 160-bit hash (40 hex characters). Deprecated for security applications.
  • SHA-256: 256-bit hash (64 hex characters). Secure and widely used.
  • SHA-512: 512-bit hash (128 hex characters). Most secure option.

Note: These are cryptographic hashes, not password hashes. For password hashing, use bcrypt, Argon2, or PBKDF2 with proper salt.
