I assume that you misunderstand. A hash has absolutely nothing to do with encryption. It's a value that's calculated from the given string using advanced math. That's why I wrote that there's no way to reverse engineer the hash to get the password.

Actually, several strings can have the same hash, although you have to be lucky to find some.

You store the hash for the password in your table. Then when you want to verify a given password, you calculate the hash for this password, and compare it to the password hash in your table.
