<p>Hi Derek<br>
</p>
<p>I have cleaned the data in the serial logs uploaded by the users
and It's pretty similar to the communications flow and meaning
described in the KG-UV8D plus, I will try to figure out if the
encryption is the same and will poke it to see if I can get it
decrypted.</p>
<p>It makes some logic that they reused the same algorithm, and even
the same key for the xor encryption. I will see.</p>
<p>[few hours later... I think I hit "send" but apparently not...]<br>
</p>
<p>So far so good, I have built a simple validation script for
individual packets and decryption seems to work, they match in the
payload size and checksum, I will try the hole data file and try
to figure some logic from it.</p>
<p>If they changed the single char encryption I think that a loop
for the 256 available chars and some intuition looking at the data
must figure it out.</p>
<p>I have to go offline now, will be back with results tomorrow.<br>

<div>If it's anything like the uv8d, the serial traffic is
encrypted. I did a bit of digging and it looks like it uses the
windows bcrypt.dll library which is a crypto wrapper. There's
also a small discrepancy in the .exe strings of the factory
software, an extra string with a value of 123456 which I suspect
to be the encryption key. Just not sure of the algorithm. Good
luck!

Has any developer make some work on this?<br>
<br>
I'm taking a peek on the logs to evaluate if I can make it.<br>
<br>
I ask the above question to not step on other developer
