Probably a very newbie question but, Ive been reading around and have found some difficulty in understanding the creation and storage of passwords. From what i've read md5/hash passwords are the best ways to store them in a database. However, how would I go about creating those passwords in the first place?
So say I have a login page with user bob, and password bob123 - how will I 1. get bobs password into the database to begin with (hashed) 2. how do I retrive and confirm the hashed password?
Edit 2017/11/09: Be sure to take a look at the answer from O Jones.
First off MD5 isn't the greatest hashing method you could use for this try sha256 or sha512
That said lets use
md5()to represent the hashing part of the process.
When you first create a username and password you will hash the raw password with some salt (some random extra characters added to each password to make them longer/stronger).
Might look something like this coming in from the create user form:
Then on login it'll look something like this:
