Like many of you, I received a brand new DP832 power supply a few weeks ago, with firmware 1.09 installed. Which means no working keygen and no possibility to downgrade...
Well... Not anymore !
I've spent quite some time reverse engineering the new firmware, and I discovered that they didn't change the signing algorithm, and not even the private key. Overall, they only added some bits shuffling (ie. obfuscation) on the final license string and they changed the options coding.
So I took the latest riglol version I found (from
http://gotroot.ca/rigol/), and added support for generating license for this new DP832 firmware. It works exactly the same as before. You just need to specify different options string depending on your DP832 firmware version. Executing riglol without parameters will list the valid options depending on firmware version.
I also found other valid options strings but they do not seem to have any effect. And as it seems there is no way to uninstall options on the DP832 (am I wrong ?), I can't check if those unknown options actually activates the same features as some other options. Anyway, here is the list of unknown options, if somebody wants to play with: FPLT, FTLT, F2PT, F4PT.
I compiled this new riglol version for linux, osx and windows, as well as the web version. It would be nice if the persons handling
http://gotroot.ca/rigol/riglol/ and
http://riglol.3owl.com/ could update their online version.
Enough talk ? You want some action ? Here you go:

And last but not least, huge thanks to everybody involved in this riglol hack, and especially to cybernet and zombie28 !
