Keyword Meaning
RTCMK Reenciphers a DES key to the current master-key in an
internal key-token in application storage or in key storage If
the supplied key is already enciphered under the current
master-key the verb returns a positive response (return code,
reason code — 0, 0). If the supplied key is enciphered under
the old master-key, the key will be updated to encipherment
by the current master-key and the verb returns a positive
response (return code, reason code — 0, 0). Other cases
return some form of abnormal response.
Required Commands
If you specify RTCMK keyword, the Key_Token_Change verb requires the
Reencipher to Current Master Key command (offset X'0090') to be enabled in the
hardware.
