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 different design goals. Bcrypt is designed to be slow to resist brute-force attacks, while scrypt is designed to be memory-intensive to thwart 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 cracking.

Are there any performance differences?

Yes, bcrypt is typically faster than scrypt, but this speed comes at the cost of security. Scrypt's memory requirements can slow down the hashing process.

When should I use one over the other?

Use bcrypt if you need a faster solution and are less concerned about hardware attacks. Use scrypt if you prioritize security and can afford the performance trade-off.
