View Full Version : How to sign and encode strings for sending data to checkout.

I am working on a simple web site to sell art. We are using Amazon check out. I am writing code in php to create the checkout buttons in a form.

I am new at this, and one thing I don't know is how to sign and encode strings. The Amazon web site assumes I know how to do that.

Can someone point me at a beginner level page that would teach me the basics of signing and encoding strings.
