The return code specifies the general result of the callable service. Appendix A. ICSF and TSS Return and Reason Codes lists the return codes.

The reason code specifies the result of the callable service that is returned to the application program. Each return code has different reason codes that indicate specific processing problems. Appendix A. ICSF and TSS Return and Reason Codes lists the reason codes.

The length of the data that is passed to the installation exit. The length can be from X'00000000' to X'7FFFFFFF' (2 gigabytes). The data is identified in the exit_data parameter.

The data that is passed to the installation exit.

A 64-byte string variable containing an external key token. The external key token contains the key to be re-enciphered (translated).

A 64-byte string variable containing the internal key token or the key label of an internal key token record in the CKDS. The internal key token contains the key-encrypting key used to decipher the key. The internal key token must contain a control vector that specifies an importer or IKEYXLAT key type. The control vector for an importer key must have the XLATE bit set to 1.

A 64-byte string variable containing the internal key token or the key label of an internal key token record in the CKDS. The internal key token contains the key-encrypting key used to encipher the key. The internal key token must contain a control vector that specifies an exporter or OKEYXLAT key type. The control vector for an exporter key must have the XLATE bit set to 1.

A 64-byte string variable containing an external key token. The external key token contains the re-enciphered key.

ICSF supports two methods of wrapping the key value in a symmetric key token: the original ECB wrapping and an enhanced CBC wrapping method which is ANSI X9.24 compliant. The output_key_token will be wrapped in the same manner as the input_key_token.
