Hello,

I have the DrayTek Vigor2920 configuration file but it can't extract the password from the backup configuration file. Here is the log:

I have check that the def de_cfg(self, data) method does not work. I have print the array after processing and it all the \x00.

Some modules are hardcoded to use HTTP even though they reliably work through HTTPS. Add support for SSL where possible.

I have installed 2.9.1 version of request python package using pip but still it is not able to detect it. Have a look at the image down below.

Module core.compression.lzs not working properly. Code was probably for python2 and is not working properly under python3 even after modification. Problem is most probably in RingList.

Necessary for rom-0.py decryptor
