The Key_Translate verb uses one key-encrypting key to decipher an input key and
then enciphers this key using another key-encrypting key within the secure
environment.
Specify the following key tokens to use this verb:
The external (input) key-token containing the key to be reenciphered.
The internal key-token containing the IMPORTER or IKEYXLAT
key-encrypting-key. (The control vector for the IMPORTER key must have the
XLATE bit set to one.)
The internal key-token containing the EXPORTER or OKEYXLAT
key-encrypting-key. (The control vector for the EXPORTER key must have the
XLATE bit set to one.)
A 64-byte field for the external (output) key-token.
The verb builds the output key-token as follows:
Copies the control vector from the input key-token.
Verifies that the XLATE bit is set to one if an IMPORTER or EXPORTER
key-encrypting-key is used.
Multiply-deciphers the key under a key formed by the exclusive-OR of the
key-encrypting key and the control vector in the input key-token,
multiply-enciphers the key under a key formed by the exclusive-OR of the
key-encrypting key and the control vector in the output key token; then places
the key in the output key-token.
Copies other information from the input key-token.
Calculates a token-validation value and stores it in the output key-token.
