Barracuda VPN: encrypted automated scripts

I created this repository to simplify my use of barracuda vpn just with username and password in linux distributions debian based.

The goal is simple, instead of having to enter the username and password every time I want to connect or reconnect to barracuda-vpn, I just enter the vpn command in the terminal.

One RSA key are created as root and the credentials are stored in a encrypted file using this RSA key.
