webMethods Broker uses a special file called a keystore to store each Broker component's SSL certificate.

A keystore file contains one key pair, composed of a client's private key and signed certificate for its public key. The certificate contains the client's distinguished name (DN). This DN is usually associated with an alias in the Broker user interface and referred to there as the user name.

The keystore should be strongly protected with a password, and stored (either on the file system or elsewhere) so that it is accessible only to administrators.
