Abstract
A method and system for renewal of expired certificates is described. In one embodiment, a method, implemented by a computing system programmed to perform operations, includes receiving, at a certificate manager of a computing system from a requester, a certificate renewal request for an original digital certificate that has already expired, and renewing the expired certificate as a renewed certificate by the certificate manager when the certificate renewal request is approved. The renewed certificate comprises the same key pair as the original certificate, but includes a new expiration date, and wherein the renewed certificate is functionally identical to the original certificate.
