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