Disklavier

Yes, I expect there to be a difference between the E3 and the DKC850, so this 
does help show the potential differences.

Let's continue the conversation off the mailing list though, as it's already 
gotten technical, and that's not what this list is about. ;-)

We could certainly continue it on the DKVBrowser group, or privately...either 
way is better than here.

The response will *always* start with "U2FsdGVkX1/" as that is the aes 
encryption for "salted__".  Except, in this case, I think it's a red herring... 
And, the last character will always be "=".  The stuff between those is the 
important part, but I think I've got a handle on it...more to come.

Thanks again!

-Kevin

Btw, I have a dkv-800 (the E3 piano), not 850. I don't know if that makes any 
difference.

Here is another one. Seems like the first part of the response was the same and 
what follows is hexadecimal..

<rc_certificate.param="Tx7GfO1Cjif1e6aV8a3GTceUXAu64xsV5zCkmBUFT8F5eN1kX2"./>

<rc_certificate.param="U2FsdGVkX1/731748912231065dbc81e32ac0dbe5b2=".rc="iphone".passcode=""
 ./>.
