![]() However, public-key encryption does not conceal metadata like what computer a source used to send a message, when they sent it, or how long it is. Public-key encryption on its own also does not tell the recipient anything about who sent a message-it just conceals the content of a message in a ciphertext that can only be decrypted with the private key. In a digital signature system, a sender can use a private key together with a message to create a signature.Īnyone with the corresponding public key can verify whether the signature matches the message, but a forger who does not know the private key cannot find any message/signature pair that will pass verification with the public key. In fact it’s so easy for people to eavesdrop and hack a public WiFi that even a 7 year old girl can do it, in under 11 minutes! Public WiFi is something many of use enjoy while we’re at the coffee shop, hotels, airports, libraries and so on, but one thing everyone should or needs to know is that public WiFi is NOT secure. The solution would be to use a VPN which will encrypt your traffic between you and the VPN server. So even if someone is attempting to hack the public WiFi, your traffic becomes useless to them and thus your emails, chats, web browsing and file transfers are now secure and out of other peoples sight. There are plenty of VPN services available such as NordVPN (which I also use), but you can also setup your own VPN server on your Synology NAS. The Synology VPN server can be configured to use PPTP, OpenVPN, and L2TP/IPSec.After the package has been installed, open the VPN Server app.Log into your Synology NAS then open the Package Center and install the Synology VPN Server under Utilities.How to setup a Synology VPN server on a Synology NASīefore we get started installing the Synology VPN Server you will want to make sure you already have DDNS configured on your Synology NAS and familiar with how to do port forwarding on your home router. ![]() I went with OpenVPN due to being considered very secure, fast, and there is an OpenVPN client available for all my devices (Windows and Android. If you’re a MAC user, there is also a MAC client). ![]() The default setting is to allow every user VPN access.That said, on the left side click on “ OpenVPN” and then check “ Enable OpenVPN server” on the right side, then click Apply. I would suggest changing the privilege to only the user(s) you want to be able to connect to the VPN. Finally, on the left side click on “ OpenVPN” and then click on “ Export configuration” and save the openvpn.zip file, such as to your desktop as we’ll be using this soon.Īt this point the Synology VPN server is running and user(s) have been granted access to log into the Synology VPN.In this case click on Privilege, then uncheck all the check boxes expect the OpenVPN box for the user(s) you want to have access, then click on Save. There are still a few more steps needed to be completed before we are completely finished. Such as open the port on the Synology firewall (you ARE running the firewall aren’t you?) as well as setup the OpenVPN configuration files.
