Hey John Doe, I have a suggestion/experiment for you. From the pieces of info other guys have shared: Joseph and Kiti say that it works on Windows only. I think the certificate is using some certificate authority that only Windows is familiar with. Windows has a certificate store which contains a list of trusted Certificate Authorities (CAs) that Windows OS trusts. IE can access this CA store without showing the dialog boxes. However other browsers have their own CA store, and that's why you may not be able to use them with certificates signed using the Windows CA. However Kiti says that those other browsers can work provided you are in a Windows environment, it would be good if Kiti tells us which versions of those browsers he's running because the newer versions could be accessing the Windows CA store besides their own CA store. Now, about curl: I think you have 2 options: 1. Export the Windows CA store bundle and let curl point to it. If that doesn't work, try option 2 below: 2. Windows can allow you to access it's CA store. You may need to make some modifications to curl and do a custom build. The modification will be to let CURL access the windows CA store and use it to authenticate the certificate that you're getting from M-Pesa. You can Google if there already exists such a build for curl before diving into its code. Hope that makes sense.
