How do Scrypt and Bcrypt compare for password hashing?

What are the main differences between Scrypt and Bcrypt for password hashing?

Scrypt and Bcrypt are both password hashing algorithms, but they differ in design and security features. Scrypt is memory-hard, making it resistant to hardware attacks, while Bcrypt is based on the Blowfish cipher and is more CPU-intensive.

Which one is more secure for modern applications?

Scrypt is generally considered more secure for modern applications due to its memory-hard properties, which make it harder for attackers to use specialized hardware for cracking.

Are there any performance trade-offs with using Scrypt?

Yes, Scrypt can be slower and require more memory compared to Bcrypt, which might impact performance in high-load scenarios. It's important to balance security needs with performance requirements.

Can you give me examples of when to use each?

Use Bcrypt for applications with lower security needs or where performance is critical. Use Scrypt for applications requiring high security, like storing sensitive user data.
