Custom programming

IBM has created two toolkits you can use to create or extend the application program that performs within the Coprocessor. Such application programs operate within segment three of Coprocessor memory and can take full advantage of the CP/Q++ embedded operating system to perform security-sensitive tasks and/or to perform cryptographic operations.

If you wish to inquire further about the toolkits, please contact the Crypto team.
