What are the differences between bcrypt and scrypt?

What are the differences between bcrypt and scrypt?

Bcrypt and scrypt are both password hashing algorithms, but they have key differences. Bcrypt is designed to be computationally intensive, while scrypt is designed to be both computationally and memory intensive, making it more resistant to hardware attacks.

Which one is more secure?

Scrypt is generally considered more secure than bcrypt because it requires more memory, making it harder for attackers to use specialized hardware for brute-force attacks.

Are there any performance differences?

Yes, bcrypt is typically faster than scrypt due to its lower memory requirements. However, the performance can vary based on the implementation and the system it's running on.

When should I use one over the other?

Use bcrypt if you need a faster hashing algorithm and are less concerned about memory usage. Opt for scrypt if security is your top priority and you want to protect against hardware attacks.
