frequently asked questions
what cost factor should I use?
10 to 12 is typical today. each +1 doubles the time. high values can take several seconds in a browser.
can I verify an existing hash?
yes, use the verify section: paste the hash and a password to see whether they match.
is my password sent anywhere?
no. bcryptjs runs in your browser; the library itself is downloaded from a CDN.
