Abstract

System, method and program product for updating a current encryption certificate with a new encryption certificate in a computer having a first plurality of communication channels which require an encryption certificate and a second plurality of communication channels which do not require an encryption certificate. The computer stores the current encryption certificate. The first plurality of communication channels are active and use the current encryption certificate for communication. The second plurality of communication channels are also active. The first plurality of communication channels are deactivated without deactivating the second plurality of communication channels, while substituting the new encryption certificate for the current encryption certificate for subsequent use by the first plurality of communication channels. After the substitution, the first plurality of communication channels are reactivated. After the reactivation, the computer communicates with another computer via one of the first plurality of communication channels using the new encryption certificate.
