Remarks

A PlayReady certificate chain is a digitally-signed binary document. Certificate chains are composed of one or more individual certificates in a hierarchy. Each certificate in the hierarchy is signed by the entity above it, except for the root certificate, which is signed by Microsoft. External components can recognize the certificate as coming from a trusted source and verify that it has not been tampered with by validating the signatures of each certificate in the chain. Certificate chains are presented to other entities during DRM operations, which in turn can verify the validity of the certificate itself and check to determine whether it is has been revoked.
