摘要：
Systems and methods for updating status of digital certificate subkeys. A request is made to a key server to verify if a given key is revoked. If it is not, then the key with its subkeys is acquired from the key server. If one or more subkeys or signatures of the subkeys are different in the acquired key, then the key is replaced.
