KEYLABL2 parameter

Parameter type

Keyword, optional

Purpose

Use the KEYLABL2 to specify 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.

Code the KEYLABL2 parameter when you want to:

Specify the label for the key encrypting key used by the Encryption Key Manager, or
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.

At least one of KEYLABL1 or KEYLABL2 must have a private key associated with it.
