Before you configure an HTTP connection or a Web Services Consumer connection to use SSL authentication, you may need to configure certificate files. If the Integration Service authenticates the HTTP server or web service provider, you configure the trust certificates file. If the HTTP server or web service provider authenticates the Integration Service, you configure the client certificate file and the corresponding private key file, passwords, and file types. You can generate client certificate and private key files by running the OpenSSL commands.
The trust certificates file (ca-bundle.crt) contains certificate files from major, trusted certificate authorities. If the certificate bundle does not contain a certificate from a certificate authority that the session uses, you can convert the certificate of the HTTP server or web service provider to PEM format and append it to the ca-bundle.crt file.
