I need a little help from you, I have an exercise , to do a login program and to store the password with sha-256 and salt, I made a part, but here it's the hard part. I've read that if you use sha-256 that you can't reverse the operation to determine the password. If it's true then what I need to use to encrypt the password and after I encrypt the password, how can I login if the password is encrypted?
PS: I've searched on google.
