PBKDF2 vs Argon2

Developers should learn and use PBKDF2 when implementing password storage or key derivation in applications that require secure handling of user credentials, such as authentication systems, encryption tools, or data protection mechanisms meets developers should use argon2 when implementing secure password storage in applications, as it provides strong protection against brute-force and side-channel attacks. Here's our take.

PBKDF2

Nice Pick

Developers should learn and use PBKDF2 when implementing password storage or key derivation in applications that require secure handling of user credentials, such as authentication systems, encryption tools, or data protection mechanisms

Pros

• It is particularly useful in scenarios where passwords need to be hashed with added resistance to dictionary and rainbow table attacks, as recommended by security standards like NIST for password-based key derivation
• Related to: cryptography, password-hashing

Cons

• Specific tradeoffs depend on your use case

Argon2

Developers should use Argon2 when implementing secure password storage in applications, as it provides strong protection against brute-force and side-channel attacks

Pros

• It is particularly valuable in web applications, authentication systems, and any scenario where user credentials need long-term protection, such as in databases or authentication servers
• Related to: password-hashing, cryptography

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. PBKDF2 is a concept while Argon2 is a tool. We picked PBKDF2 based on overall popularity, but your choice depends on what you're building.

The Bottom Line

PBKDF2 wins

Based on overall popularity. PBKDF2 is more widely used, but Argon2 excels in its own space.
