Abstract: The system, method, and program of this invention provides a secure configuration of a digital certificate for a printer. The printer has a unique encryption key stored in it at manufacturing time. This key is also recorded in a database, securely controlled by a certificate authority, and the key is associated with the printer by model and serial number. The printer sends a message requesting a digital certificate to the certificate authority. In the message request, the printer sends the model number and serial number of the printer in the clear, i.e., not encrytped, which is needed by the certificate authority to look up the unique encryption key in the database. The message request also contains an encryption, using the built-in key, of some of the same information that was sent in the clear. The database needs the information in the clear to get the key.
