I am not certain of what you are asking, however if you are planning on encrypting something with a third-party component, you would need to know how that component works and be able to program to it. Using that component in an automation would be no different than using any other component. Public and static methods, properties, and events would be visible in the Object Explorer window. You'd likely need to copy the assemblies to the installation directory of Pega Robotics Studio (or the Plugin) to use them along with any related assemblies. You will also likely need to add references to each assembly and ensure they are included in the deployment package. I can't really offer you any specific about coding to an unspecified third-party component, but I am certain that the component would be documented from its provider.

Add the respective DLLs under references and in script component write the encryption logic as per your requirement then use this method in the automation.
