I need to use PHP to invoke an external SOAP web service that resides in a webserver.
The web service requires that a digital signature shall be used to establish the connection.
The web service must have a signature.
Some items on the xml web server file must be encrypted with an AES symmetric key. But when accessing the test environment the web service provider sent us two files
a file with an extension .cer and another one with .pfx extension.
Which of them and how can I use this in my PHP script to build the xml. Is there any example you can send to me?
