Capella's SecureDIMM card

Capella's SecureDIMM II (Dual Inline Memory Module) card supports (AES) Rijndael decryption on selected Hewlett‑Packard (HP) printer models. This means that CA Spool can send print data securely over the public TCP/IP network to remote HP printers. SecureDIMM uses 16 bytes persistent encryption keys.

The SecureDIMM package includes a Printed SecureDIMM User Guide and a SecureDIMM CD which contains:

• The CryptTst.prn test file, which prints a picture of a Volkswagen if the encryption card functions.
• The aesCrypt Utility to encrypt a file and to change the printer encryption key.
• Windows SecureDIMM Print Driver Extension used to specify the encryption key and enable encryption.

The following is a sample print data encryption HP printer node definition:

DEFNODE PJL5,HP-PJL5                                                 
NODE    HP65,PJL5,TCPPORT=9100,TCPHOST=731.225.65.331,TCPDRIV=PJL5F4,  
        KEY=010102030405060708090a0b0c0d0e0f,                      
        GROUP=1

To change or reset a Capella SecureDIMM card decryption key, create and print a CA Spool file named AESCRYPT as follows:

//*
//O1  OUTPUT CLASS=A,DEST=HP6,                     
//    USERDATA=(-C,                        -C / -R 
//      000102030405060708090A0B0C0D0E0F,  OLD-KEY 
//      010102030405060708090A0B0C0D0E0F)  NEW-KEY 
//STEP1  EXEC PGM=IEBGENER                         
//SYSPRINT DD SYSOUT=*                             
//SYSUT2   DD SUBSYS=(ESF,A,AESCRYPT),OUTPUT=*.O1 
//SYSIN    DD DUMMY                                
//SYSUT1   DD *
