- Higher cost factors are slow by design; cost 14 can take several seconds in a browser.
Frequently asked questions
Why does the same password give a different hash each time?
bcrypt embeds a random 128-bit salt in every hash. Verification reads the salt and cost from the stored hash, so any of them will match the password.
