Abstract: A certificate authority service receives a request to issue a short-duration digital certificate usable for authentication of a server of an entity. The request includes a long-duration digital certificate that is not usable for authentication of the server of the entity, the long-duration certificate being usable for validation purposes between the entity and the service. The service determines whether to issue the short-duration digital certificate based on a validity period that is specified in the long-duration digital certificate. Based on the determination, the service issues the short-duration digital certificate that includes a shorter validity period than the long-duration digital certificate. The short-duration digital certificate may enable a client to authenticate the entity and securely communicate with the entity.
