Decrypt Configuration File

Disclaimer: - This is Only for educational purposes, No one is responsible for any type of damage.

1. Make sure you have openssl installed or else install it and add it to environment variable PATH.
2. Grab the key for your router model from here.
3. Go to Your Router WEB-UI Page (http://192.168.29.1) and Sign in as Admin. (The default credentials are admin : Jiocentrum)
4. Go to Administrator --> Maintenance and click Backup.
5. A file (RSTXXXXXXX_JCXXXXX.enc) will be downloaded with .enc extension.
6. Open up Terminal or Command Prompt.
7. Decrypt the downloaded .enc file using the command openssl aes-128-cbc -d -kfile "<path to the key file>" -in "RSTXXXXXXX_JCXXXXX.enc" -out "RSTXXXXXXX_JCXXXXX.txt"
8. RSTXXXXXXX_JCXXXXX.txt contains the decrypted configuration. You might view or edit it at your own risk as your router may get bricked due to incorrect configuration (A hard reset might fix it. Just push the button (inside a hole) behind the router for about 30 seconds)
9. You may also want to encrypt the configuration file after editing it and restore it. Instructions to do so are here.
