Bcrypt
overall review score: 4.7
⭐⭐⭐⭐⭐
score is between 0 and 5
bcrypt is a popular cryptographic hashing algorithm designed for securely storing passwords. It incorporates a salt to protect against rainbow table attacks and is intentionally computationally intensive to slow down brute-force attempts, making it a widely used method for password security in modern applications.
Key Features
- Adaptive key derivation function that adjusts computational cost over time
- Incorporates salting to prevent rainbow table attacks
- Designed explicitly for hashing passwords with resistance to brute-force attacks
- Available in multiple programming languages and libraries
- Configurable work factor (cost parameter) to balance security and performance
Pros
- High security for password storage due to salting and adaptive difficulty
- Widely supported and trusted in the industry
- Protects against common attack vectors like rainbow tables and brute force
- Flexible cost parameter allows balancing between performance and security
Cons
- Computationally intensive, which may impact system performance if not properly tuned
- Requires careful configuration of the cost factor to avoid vulnerabilities or slowdown
- Not suitable for general purpose hashing beyond passwords due to its design focus
