Key label 1 specification - Key = '8023'

DALKYL1 specifies the label for the key encrypting key used by the key manager. The key encrypting key is used to encrypt the data (encryption) key.

When you code DALKYL1, # must be one, LEN must be 1 to 64, and PARM contains the key label in EBCDIC. You must also include the DALKYC1 text unit.

Code the DALKYL1 text unit to do either of the following tasks:

Specify the label for the key encrypting key used by the encryption key manager.
Override the label for the key encrypting key defined in the data class of the data set.

Specification of the key labels does not by itself enable encryption. Encryption must be enabled by a data class that specifies an encryption format, for example EEFMT2. For complete documentation on using tape encryption, see z/OS DFSMS Software Support for IBM System Storage TS1140, TS1130, and TS1120 Tape Drives (3592).

Example: To specify a key label 1 of "LABELQ1.LABELQ2.LABELQ3", code:

KEY    #     LEN   PARM
8023   0001  0017  D3C1C2C5D3D8F14BD3C1C2C5D3D8F24BD3C1C2C5D3D8F3
