                      terminated and when there are less then 16 characters,
                      those left tailing will be spaces (0x20)).
    16       1    u8  Magic (should be 0x1A)
    17       2   u16  Key1 (minutes:hours from DOS get sys time 0x21 AH=2C)
    19       2   u16  Key2 (1/100second:seconds from DOS get sys time)
    21       ?    u8  Garbage byte, the amount of garbage bytes will depend
                      on Key1 and Key1 (calculated after the first full cipher
                      iteration). Garbage bytes are generated by the cipher
                      function.
