You can use KGUP to generate DES and AES keys in either an operational form or an exportable form. When KGUP generates a key in the operational form, it stores it in the CKDS. When KGUP generates a key in exportable form, you can send it to another system.
To specify the function that you want KGUP to perform, you use KGUP control statements. For a detailed description of how to use the program to generate keys, see Managing Cryptographic Keys Using the Key Generator Utility Program.
