CCA Release 2.54 PKA_Symmetric_Key_Import
Restrictions
1. Private key key-usage controls can prevent use of specific private keys in this
verb. See page 3-7. A key-usage flag bit (see offset 050 in the private-key
section) must be on to permit use of the private key in the decryption of a
symmetric key.
2. The RSA private-key modulus size (key size) is limited by the Function Control
Vector to accommodate potential governmental export and import regulations.
3. Under PKA92, the EID enciphered with a key-encrypting key cannot be the
same as the EID of the importing cryptographic engine.
4. Other IBM implementations of this verb may not support:
Key types other than a default DATA control-vector
Use of a key label with the target key identifier.
Check the product-specific literature for restrictions.
| 5. Beginning with Release 2.53, a private key with the CLONE attribute is rejected
| by this verb with return code 8, reason code 64 (decimal).

Parameters
For the definitions of the return_code, reason_code, exit_data_length, and exit_data
parameters, see “Parameters Common to All Verbs” on page 1-11.
rule_array_count
The rule_array_count parameter is a pointer to an integer variable containing
the number of elements in the rule_array variable. The value must be one for
this verb.
rule_array
The rule_array parameter is a pointer to a string variable containing an array of
keywords. The keywords are eight bytes in length, and must be left-justified
and padded on the right with space characters. The rule_array keywords are
shown below:
