Decrypting G3100 config #12

Open superswan opened 10 months ago

Hello, I was wondering if there is any information on decrypting the config for a G3100, the config file is exported as .cfg and not a bin, not sure if it has a different file structure and/or encrypted differently. 

Traceback (most recent call last):
  File "/home/debbie/decrypt.py", line 59, in <module>
    main()
  File "/home/debbie/decrypt.py", line 45, in main
    json_data = decrypt(data_in)

I'm having a similar issue with a G3100.
