Abstract

A method includes receiving at a first computer a new certificate which is to replace an old certificate associated with the first computer and associating by the first computer the new certificate with the first computer. In response to the first computer associating the new certificate with the first computer, the first computer accesses an email address book of the first computer having information identifying a second computer as having received the old certificate to determine from the information that the second computer is to associate the new certificate in place of the old certificate with the first computer. In turn, the first computer transmits the new certificate to the second computer for the second computer to associate the new certificate with the first computer.
