SOAP over HTTPS Scenario.

Experts,

I am using PO 7.31 Single Stack.

I am going to integrate with some Third-Party System ( B2B ) Scenario. As its B2B client want this to integrate this over SSL.

We are using SOAP Communication channel at Source side.

We have shared a PI WebService to third Party and told them to send data on this endpoint.

I have changed following things in webservice( http to https and port no to ssl port no).

Now Certficate part always confuses me So I have question over certificates/ PubliC/ Private Key :-

1. Who will provide Certificate and to whom ??

2. What kind of certificate will be shared accross parties ?? such as public private ?? PGP or X.509 ??

I have gone through many blogs - but i am still confused.
