Bcrypt Hash Checker
Check whether a password matches a bcrypt hash. Free and private: runs in your browser.
Enter the password, a line with ---, then the bcrypt hash to verify they match.
Hashing runs locally in your browser. Your input never leaves this page.
Use cases
- Verify a download or file checksum.
- Create test fixtures for authentication code.
- Debug a hash mismatch between two systems.
Frequently asked questions
Why does the same password give a different bcrypt hash each time?
Each hash includes a new random salt. Verification reads the salt from the stored hash, so a match still works.
Is the Bcrypt Hash Checker free?
Yes. It is free with no sign-up, and it runs entirely in your browser, so your input is never uploaded or stored.
Is hashing the same as encryption?
No. A hash is one-way: you cannot get the input back. Encryption is reversible with a key. Use slow password hashes (bcrypt, Argon2, PBKDF2) for passwords and fast hashes (SHA-256) for integrity checks.
