Hash passwords with bcrypt using a tunable cost factor. Get salted, adaptive hashes that resist brute force as hardware improves.

Why Bcrypt for Passwords

Bcrypt is a slow, salted password hashing function. Its adjustable cost makes attacks expensive and adaptive over time.


Generate Secure Bcrypt Hashes

Step-by-Step

  1. Enter password; never log the raw value.
  2. Choose cost (10–14 typical; higher = slower).
  3. Generate the full hash string (includes salt and cost).
  4. Store hash only; verify with constant-time comparison.

Operations Guidance

  1. Rehash when you raise the cost parameter.
  2. Use MFA and rate limiting in addition to hashing.
  3. Prefer Argon2id where available, but bcrypt remains widely supported.


Pitfalls to Avoid

Don’t Do This

  1. Storing plaintext or MD5/SHA hashes of passwords.
  2. Comparing with naive string equality (timing leaks).
  3. Reusing salts or truncating hashes.
