From Page 3 of the Data Class
Define panel, use the DOWN command
to view Page 4, on which you specify the key labels and encoding mechanism.
- Key Label
- Specifies the label for the
key encrypting key used by the Encryption
Key Manager. The key encrypting key is used to encrypt the data (encryption)
key. To specify the key label value, you can use up to 64 characters
with blanks padding the field on the right. The characters can be
alphanumeric, national, or special characters with some additional
characters also allowed. It is treated as a free form field on input
and validity checked by the control unit when the key label is first
used and converted from EBCDIC to ASCII. The characters specified
through ISMF must map to ASCII characters X'20' to "7E'.
- Encoding Mechanism
- Specifies how the label for
the key encrypting key specified
by the key label (input) is encoded by the Encryption Key Manager
and stored on the tape cartridge.
- L = encoded as the specified label
- H =
encoded as a hash of the public key
