OpenVPN protocol (TCP and UDP)
The RingVPN solution offers a range of VPN protocols to access the network securely. Once RingVPN is launched, you can actively change the protocol or let the application choose the most suitable one for your browsing; it will use the most efficient parameters.
The open-source OpenVPN protocol uses certificates that can be likened to a digital identity card (just like those used by the https protocol). In order to protect the workstation against hacker attacks, each certificate is validated by precise specifications which are essential to ensure maximum security. RingVPN uses an RSA certificate which, at 4096 bits, is twice the required minimum RSA length.
