How to use the Hash Generator

  1. Type or paste the text.
  2. Choose one algorithm or all of them, plus an optional HMAC key.
  3. Copy the hash, or paste an expected hash to check for a match.

Why use this Hash Generator

  • Five algorithmsMD5, SHA-1, SHA-256, SHA-384 and SHA-512 in hex or Base64.
  • HMAC supportAdd a secret key to compute keyed hashes.
  • Hash by lineProcess a list and get one hash per line.
  • Match checkerPaste a published checksum to see if it matches.

Frequently asked questions

Is MD5 safe for passwords?

No. MD5 and SHA-1 are broken for security. Use them only for checksums, and use a password hashing function such as bcrypt or Argon2 for passwords.

What is HMAC?

HMAC mixes a secret key into the hash so only someone with the key can produce or verify it.

Is my text sent to a server?

No. Hashes are computed in your browser.
