Key_Generate CCA Release 2.54
can use to generate a single key copy with default control-vectors. Figure 5-12 on
page 5-49 shows the key types you can use to generate two copies of a key. An
‘X’ indicates a permissible key type for a given key-form. An E indicates that a
special (Extended) command is required as those keys require special handling.
You can generate a single-length key with any control vector value
9
. when you
specify SINGLE and OP. In this case, the verb uses the Generate Key command
(X'008E')
If you encode the key type in a control vector supplied in a key token (and use the
TOKEN key-type keyword), remember that non-default control vector values for the
key type can be employed.
Certain key-type keywords have an asterisk (*) indicating that these keywords are
not recognized by the verb as key type specifications. Nevertheless, those key
types are supported when supplied as control vector values.

Note:
1. The key types marked with an * must be requested through the specification of a
proper control vector in a key token and the use of the TOKEN keyword.
2. Additional key types can be generated as operational keys when you supply key
form as OP, key type as TOKEN, key length as eight space characters, and provide
the desired control vector in the key token specified by the
generated_key_identifier_1 parameter.

The command-level architecture permits many CV values and value-pairs to be generated so long as they adhere to rules defined
in that architecture. It is beyond the scope of this publication to explain all permissible combinations. Only those with defined
usage are shown in the tables.
