FAQ
Bcrypt is a password-hashing function designed to be computationally expensive, making brute-force attacks impractical. It incorporates a configurable salt and work factor (cost).
Salt rounds (cost factor) determine how many times the hashing algorithm is iterated. Each increment doubles the computation time. A value of 10-12 is recommended for most applications.
Bcrypt is intentionally slow to resist brute-force and dictionary attacks. The slowness is a security feature — it makes it expensive for attackers to try many password guesses.
No. All hashing and verification happens locally in your browser using the bcryptjs library. Your password never leaves your device.
