How do I implement salt in my application?

To implement salt, you first need to generate a unique salt value for each user. This can be done using a secure random number generator.

What should I do with the salt once I have it?

You should concatenate the salt with the user's password before hashing it. This way, even if two users have the same password, their hashes will be different.

How do I store the salt securely?

You can store the salt alongside the hashed password in your database. Just ensure that both are securely stored and protected.

Is there a specific hashing algorithm you recommend?

Yes, I recommend using a strong hashing algorithm like bcrypt, Argon2, or PBKDF2, as they are designed for password hashing.
