Bcrypt Generator and Verifier

Higher cost values are slower by design. The interface caps cost at 14 to avoid unexpectedly freezing the page.

Designed for passwords

Bcrypt includes a random salt and configurable work factor, making guesses deliberately more expensive than a general-purpose hash.

Verification does not decrypt

Bcrypt compares a password candidate with a stored hash. The original password cannot be recovered from the hash.
