Hash a password with bcrypt, or verify a password against an existing bcrypt hash.
Runs entirely in your browser, nothing is uploadedHigher costs are slower to compute, on purpose, which is what makes bcrypt resistant to brute-force guessing. 10-12 is a common default; above 12 can take a noticeable moment in the browser.

The field is masked and the value stays in the page.
Hashing applies bcrypt at the cost factor you choose. Verifying compares a password against a hash you paste in.
A bcrypt hash carries its own salt and cost, which is why the same password produces a different hash every time.
Compute SHA-1, SHA-256, SHA-384, and SHA-512 checksums for any file, to verify it wasn’t altered.
