A typical application server is deployed with a truststore file, which contains the trusted certificates. To add a certificate, you use the keytool utility to update the cacerts.jks file or the equivalent server-level truststore file, and then you restart the server.

Pega Platform includes a platform truststore to which you can import X.509 certificates. When a certificate needs to be used for transport layer security, Pega Platform looks for the certificate in the platform truststore, and then in the application server-level (JVM) truststore. You can add certificates to the platform truststore without having to restart the server, which is useful when TLS certificates are changed for reasons such as key expiration.

The platform truststore is used for rules that reference a truststore, which include certificates used for transport layer security in connectors and integration services, keystores, authentication services, OAuth 2.0 providers, and web service policies.

To view and update the platform truststore, run the activities described below using Dev Studio.

1. To view the contents of the platform truststore, run the pyInstanceList report of the Data-Admin-Security-Certificate class.
2. To add, update, and delete certificates in the platform truststore, run the appropriate activities in the Data-Admin-Security-Certificate class. For more information, see Managing X.509 certificates.
