Abstract:
An information processing apparatus includes an application that encrypts document data using a public key of a spooler and stores the document data encrypted as a spool file. A printer driver decrypts the encrypted document data using a secret key of the spooler and performs rendering to generate print data. Subsequently, the application decrypts the print data using the public key of the printing apparatus. The printing apparatus decrypts the encrypted print data using the secret key of its own.
