bcrypt Generator
Hash and verify passwords using the bcrypt algorithm securely in the browser.
This browser-side tool uses SHA-256 (bcrypt-style rounds) for educational UX. It is not real bcrypt, but it demonstrates configurable work factors fully in the browser.
Verify
Generate a hash or paste one above to verify.
Frequently Asked Questions
Is the bcrypt Generator secure?
Yes. All cryptographic operations use the browser's built-in Web Crypto API, a FIPS-approved implementation. Everything runs client-side — no keys, passwords, or tokens are ever sent to a server.
How does hash work in this tool?
This tool leverages the browser's native Web Crypto API to perform hash operations. The algorithm executes entirely inside your browser's JavaScript engine so your sensitive data is never exposed to any external service.
What is the difference between bcrypt and encryption?
Bcrypt typically produces a fixed-length output that cannot be reversed, making it ideal for verification and integrity checks. Encryption is a two-way process that allows the original data to be recovered with the correct key.
Can I use bcrypt Generator offline?
Yes. When you install Web Developer Toolbox as a Progressive Web App (PWA), the bcrypt Generator works fully offline — the service worker caches all assets so no internet connection is required.
How long should my bcrypt be?
Current industry best practices recommend at least 128 bits (16 bytes) for tokens and at least 256 bits for cryptographic secrets. Longer values provide significantly stronger security guarantees against brute-force attacks.
