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.

Frequently Asked Questions
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.
