Crypto.EncryptBlock
This command encrypts an 8-Byte data block given in the
Block parameter using the SkipJack algorithm. If
KeyIndex is set to 0x00, KeyValue will be used as
encryption key. Otherwise, KeyIndex is interpreted as
the index of the corresponding entry in the internal key list.
KeyIndex = 0x01 denotes configuration value 0x81,
KeyIndex = 0x02 denotes configuration value 0x82, etc.
