Hi Sean,
So let me actually answer your questions.
First, VPN adds about 15% overhead or so to the data stream. If you figure
about 1500 byte packets normally for data using a VPN typically reduces the
available packet size depending on the cypher and protocol type down to about
1360 bytes per packet. This is because you now have a wrapper for each packet
that contains the actual encrypted data along with the envelope created by the
VPN to appropriately route the packet to the VPN server where it’s disassembled
and decrypted and sent on it’s way to it’s final destination. This is a rough
approximation but you get the idea.
The cost factor then is take your average stream size for listening to
the radio and add 10 - 20 % to that number. There are things that can offset
some of this. Some VPNs for example offer data compression but with radio
remember that data is already compressed most likely so you might not gain that
much extra and in fact might actually lose advantage because now you’re adding
a header for compression as well as one for the VPN itself.
Now if you want a lot more control over these type of things and how much data
is used by which features you can roll your own VPN. I personally use Open
VPN. This requires a server out on the internet which you can rent for less
than $5 US per month, a free client that’s available for any Computer OS, IOS
and Android and a little time and patients. You install the Open VPN server on
the remote server you rent, you install the client on your device of choice,
you then generate certificates for authentication and a configuration for the
server side as well as a specific configuration for your device of choice.
When ever you want to connect you press one button, things negotiate and bam
you’re up and running. Many low cost virtual server providers like Digital
Ocean allow you to build your server in many different countries and you’re
also not charged per device. Say you have 10 devices you want to secure, the
cost is the same for all 10 as it is for 1. The key size and even
authentication having are totally under your control so if you’re paranoid like
me you can build very large 4096 bit keys and use SHA-512 as your data
authentication hash which is far beyond military grade.
Let me know if that helps or if you need any further details.
Thanks
Scott
