Bcrypt Generator & Checker — free online

If you store passwords, you don't keep them as plain text — you keep a hash. Bcrypt is one of the common ways to do that, and sometimes you just need to make one quickly, or check that a password matches a hash you already have. We added a free tool that does it — Bcrypt Generator & Checker — right in your browser.

What it does

You type a password and it builds a bcrypt hash for you. You can pick the cost, from 4 up to 14, which sets how much work goes into the hash. It also works the other way around: paste a password and an existing hash, and it tells you whether they match.

Nothing leaves your device

The whole thing runs inside your browser. Your password and the hash stay on your computer — nothing is uploaded to a server, and nothing is saved after you close the tab.

How to use it

  1. Open Bcrypt Generator & Checker and type your password.
  2. Choose a cost between 4 and 14, or paste a hash to check a password against it.
  3. Copy the hash, or read the match result.

It's free with no limit. There are more small tools on the Apps page.
