How do I choose the right hash function for my application?

Choosing a hash function depends on your specific needs. Are you looking for speed, security, or a balance of both?

I need it for password storage, so security is my main concern.

In that case, consider using functions like bcrypt, Argon2, or PBKDF2, as they are designed for secure password hashing.

What makes these functions more secure than others?

They incorporate techniques like salting and key stretching, which make them resistant to brute-force attacks.

Are there any performance trade-offs I should be aware of?

Yes, while these functions are more secure, they can be slower than simpler hash functions. It's important to find a balance based on your application's needs.
