Abstract
A method of renewing a plurality of digital certificates includes receiving, at a first time, a request from a user to renew a first digital certificate and determining an expiration date for the first digital certificate. The method also includes receiving, at a second time, a request from the user to renew a second digital certificate and determining an expiration date for the second digital certificate. The expiration date for the second certificate is later than the expiration date for the first certificate. The method further includes determining a new expiration date occurring after the first time and the second time and renewing the first digital certificate. An expiration date for the renewed first digital certificate is equal to the new expiration date. Moreover, the method includes renewing the second digital certificate. An expiration date for the renewed second digital certificate is equal to the new expiration date.
