Hi there,
I'm pretty new to php so bare with me on this one. Shop is working so far, no issues. I want to sell software with the ability of authorisation on the customers machine on payment success. Reading through my "orders" table and recognise if a customer has a successful payment on a specific product id seemed simple in php. But I can't just authorise a software based on the clients name and email address. So I need to create a login on the client software. For the validation of the login I need to verify the given password with the password stored in the "customers" table in the db. I see that along with the encrypted password is a "salt" stored in the table, which I understand plays a role in the decryption.

What is the method to verify the given password with the encrypted password and the salt?

I'm using the $_POST method to receive the data from the client software, if that is of any relevance.
