Extracting a signer certificate
WebSphere® Application Server uses the certificates that reside in keystores to establish trust for a Secure Sockets Layer (SSL) connection. The first step in enabling IBM® Process Designer users to access is to extract the appropriate signer certificate from the remote WebSphere Application Server instance. The extracted certificate is saved as Distinguished Encoding Rules (DER) file that you can then install in your local trust store.
