About this Tool
Use this bcrypt generator to create encoded bcrypt password hashes locally in your browser. Select an appropriate cost factor and remember that production authentication should perform hashing in a trusted application environment.

- Hash a password with cost 12
- Generate a bcrypt test hash
Frequently Asked Questions
What is the bcrypt cost factor?
The cost factor controls how many hashing rounds are performed. Higher values increase resistance to brute-force attacks but also require more processing time.
Does bcrypt include a salt?
Yes. A bcrypt hash contains the algorithm version, cost factor, salt and resulting password hash.
Can bcrypt be calculated in the browser?
Yes. A browser-compatible JavaScript or WebAssembly implementation can calculate bcrypt hashes locally.
