About Bcrypt

Bcrypt is a password hashing function designed to be slow and computationally expensive, making it resistant to brute-force attacks. It incorporates a salt to protect against rainbow table attacks and allows you to adjust the cost factor (rounds) to increase security as computing power improves.

Security Benefits
  • Adaptive cost factor
  • Built-in salt protection
  • Resistant to GPU attacks
  • Widely vetted and trusted
Best Practices
  • Use at least 10 rounds
  • Never store plaintext passwords
  • Use unique salts for each password
  • Combine with other security measures
Security Best Practices

Always use bcrypt for password hashing, not fast hashes like MD5 or SHA.

Use sufficient rounds - start with 10 and adjust based on your server performance.

Never expose plaintext passwords in logs, error messages, or client-side code.

Implement rate limiting on authentication endpoints to prevent brute-force attacks.

Combine with multi-factor authentication for enhanced security.
