About Bcrypt Hashing
What is Bcrypt?
Bcrypt is a password hashing function designed to be slow and computationally expensive, making it resistant to brute-force attacks. It automatically incorporates a salt to protect against rainbow table attacks.
Hash Format
A bcrypt hash follows this format:
Cost Factor Guidelines
| Cost | Iterations | Est. Time | Recommendation |
|---|---|---|---|
| 8 | 256 | ~10ms | Development only |
| 10 | 1,024 | ~100ms | Minimum for production |
| 12 | 4,096 | ~400ms | Good balance |
| 14 | 16,384 | ~1.5s | High security |
Best Practices
- Use cost factor 10 or higher for production
- Increase cost factor as hardware improves
- Never store plain text passwords
- Always use the verify function, never compare hashes directly
- Consider using Argon2 for new applications
Algorithm Versions
- $2a$ - Original bcrypt specification
- $2b$ - Fixed a bug in OpenBSD implementation
- $2y$ - PHP-specific version (compatible with 2b)
