Encrypted data processing method, encrypted data processing program and encrypted data processing apparatus

A computer-readable storage medium stored therein an encrypted data processing program which operates on an image forming apparatus or a RIP server each connected via a communication network to a host which transmits print data or encrypted data generated by encrypting the print data, the program causes a computer to have functions of:

• a data analysis section which analyzes the print data and instructs printing;
• a data decryption processor which decrypts the encrypted data;
• and
• an encrypted data controller which stores the encrypted data into a storage section, and reads out the encrypted data in cases where a password has been inputted,
• wherein the data analysis section determines whether transmitted data from the host is the encrypted data, and in cases where the transmitted data is the encrypted data, allows the data decryption processor to decrypt the encrypted data, and in cases where decryption of the encrypted data has been successfully executed, analyzes the print data and instructs printing, and in cases where the decryption of the encrypted data has failed, allows the encrypted data controller to store the encrypted data into the storage section.
