Argon2 (winner Of The Password Hashing Competition)
overall review score: 4.8
⭐⭐⭐⭐⭐
score is between 0 and 5
Argon2 is a modern, memory-hard password hashing algorithm that was the winner of the Password Hashing Competition (PHC) in 2015. Designed to enhance security against brute-force and hardware-based attacks, it offers flexible configurations to balance security and performance, making it a popular choice for secure password storage and cryptographic applications.
Key Features
- Memory-hard design to resist GPU and ASIC attacks
- Configurable parameters for time cost, memory cost, and parallelism
- Multiple variants: Argon2d (data-dependent), Argon2i (data-independent), Argon2id (hybrid)
- Resistance to side-channel attacks when properly implemented
- Open-source and extensively reviewed by the cryptographic community
Pros
- Highly secure due to its memory-hard and configurable design
- Flexible implementation options tailored to specific security requirements
- Resistant to various attack vectors, including GPU and ASIC brute-force attacks
- Widely adopted in industry and supported by numerous cryptographic libraries
- Open source with ongoing community support and scrutiny
Cons
- Implementation complexity can lead to incorrect or insecure deployments if not carefully managed
- Performance overhead may be higher compared to older hashing algorithms like SHA-256, especially on lower-end devices
- Requires careful parameter selection to ensure optimal security without unnecessary resource consumption
