# Copyright 2017 Krystian Struzik <toner_82@tlen.pl>

#                Based on Ron Wellsted driver for Wouxun KG-UV8D.

#                KG-UV8D Plus model has all serial data encrypted.

#                Figured out how the data is encrypted and implement

#                serial data encryption and decryption functions.

#                The algorithm of decryption works like this:

#                - the first byte of data stream is XOR by const 57h

#                - each next byte is encoded by previous byte using the XOR

#                  including the checksum (e.g data[i - 1] xor data[i])

#                I also changed the data structure to fit radio memory

#                and implement set_settings function.
