about Configuring HTTPS for PTC HTTP Server and Windchill

Hi

I have never tested https before testing Windchill.
Therefore, I ask you a few ways for test it.

1. A certificate is required to configure https. Right?

2. Generate the certificate with the keytool of java and register it as a trusted certificate in java configuration. Right?

3. The directory where you install the certificate file and private key appears in the Windchill help center at <Apache> / conf /, where <Apache> is it?

4. Is there a private key required for clients to access Windchill after https configuration?

Thank you.
I really appreciate it if you reply.
