Hash Generator

Generate cryptographic hashes (MD5, SHA-1, SHA-256, SHA-512, SHA-3)

0 characters • 0 bytes

Security Notice

  • • MD5 and SHA-1 are NOT secure for cryptographic purposes
  • • Use SHA-256 or SHA-512 for password hashing
  • • For passwords, use bcrypt, scrypt, or Argon2 instead of plain hashing
  • • All hashing is done client-side in your browser

About Cryptographic Hashes

A hash function takes input data of any size and produces a fixed-size output (hash). The same input always produces the same hash, but it's computationally infeasible to reverse the process or find two different inputs that produce the same hash (collision).
