bcrypt: How Password Hashing Works and Why It Matters
Learn how bcrypt protects passwords with adaptive hashing, salt, and cost factor tuning.
What Is bcrypt?
bcrypt is an adaptive password hashing function designed in 1999 by Niels Provos and David Mazieres. Based on the Blowfish cipher, bcrypt incorporates a salt to protect against rainbow table attacks and a configurable cost factor (work factor) that controls how computationally expensive the hash is to calculate. This makes bcrypt intentionally slow — and that slowness is its primary security feature.
