How does the MTMO issue development keys and test keys?

To encourage the rapid adoption of Marlin, the MTMO provides the Development Trust Infrastructure. There are two parts to the test infrastructure. First, adopters can download from the website a set of Common Test Keys that includes a test root, test Certification Authority, and sample credentials for services and clients. Later in development, an adopter can order a set of Adopter Test Keys. The Adopter Test Keys are from the same test root, and the values in the certificates are set by the Adopter to match what will be implemented in production.
