A device (such as a printer or a network device that may be connected to the printer) that is connected to a network and which performs secure operations using an existing encryption keypair maintained within the device, generates a new encryption keypair within the device by receiving a request from another device on the network to provide an encryption key of the existing encryption keypair to the another device. In response to the request, the device determines whether an encryption key of the existing encryption keypair within the device is valid. In a case where it is determined that the encryption key of the existing encryption keypair is invalid, the device automatically deletes each key of the existing encryption keypair from the device, generates a new encryption keypair within the device and stores the new encryption keypair in the device. The device then provides a new encryption key corresponding to the requested encryption key of the new encryption keypair to another device. |
