Scrypt Verify

Check whether a password matches a PHC-encoded scrypt hash locally in your browser. This tool verifies scrypt hashes and does not decrypt them. Read more

Check a password against a scrypt PHC hash

Scrypt Verify compares a password with a PHC-encoded scrypt hash ($scrypt$ln=...,r=...,p=...$salt$digest) in your browser. A match means the password produces that digest under the embedded parameters and salt. Verification does not decrypt scrypt.

Use this page after generating a hash with the Scrypt Hash Generator, or when checking compatible PHC scrypt strings from another tool.

How to verify

  1. Enter the password.
  2. Paste the full PHC scrypt hash.
  3. Click Verify.
  4. Read Match or Not match, and inspect parsed parameters when the hash format and parameters are valid.

Invalid hashes

Malformed hashes show a validation error. This tool expects the PHC form with ln, r, and p, not a bare hex digest. For hex-only digests, recompute with the same salt and parameters in the generator and compare manually.
