VPN ?'s
Posted by: clyde

Many VPN's offer some email and internet "security," but with the CIA itself being hacked, and with some of its own military-grade hackers going free-lance, it seems that any actual internet/email privacy might be a figment of the imagination.

With email, for example, if the sender uses a VPN and the recipient does not, is communication between them exposed to all?

I'd like to understand hows to achieve whatever privacy is available—whether with VPN, other technology, or magic.

I have no experience with secure email but from what I've heard on podcasts it would require the sender and the receiver to exchange encryption keys. Then it would not matter where or how the email was transmitted.

If sender & receiver need each other's encryption keys to exchange email privately, which makes sense, then it would seem to this newbie that VPN's would be useful only if both parties in an email exchange would have to have security keys and to exchange them.

Is that right?

Ain't hiding anything.

Are y'all comfortable having every trivial remark, every question, every minute detail of your internet traffic publicized??

I don't think that a VPN will secure email between people that aren't on the same email server. Encryption will though.

My understanding is that a VPN will allow you to:
- surf the web anonymously
- connect to your server (personal or business) securely
- use public wifi more securely
- download anonymously
- bypass geofencing restrictions (ie: view netflix while traveling outside the US)

Note that the VPN provider can tell what you're doing, so you're shifting your trust. The other issue is that using VPN can slow down your data rate as there is a processor hit for encrypting/decrypting data.

You can set up your own VPN server at home so that you can remotely connect to it securely.

Some of this may not be quite accurate as it's my understanding and I'm not a VPN expert. But I did stay at a Holiday Inn within the last year.

Thanks for the insight, macphanatic. Long as you stayed at Holiday Inn within the twelvemonth, your word is gospel.

Do you mean that simply encrypting email will offer some security provided communications are with others who are also encrypted?

I'd guess that few people have encryption…

More than you think, but it is mostly Healthcare, Government, and some Education.

My understanding is if both parties have the encryption key, it's pretty secure. Not sure how you securely share the key thought as emailing a key could get intercepted.

I am not sure I agree that a VPN provides anonymous web browsing. Google is going to know who you are thru cookies on your computer. I think to anonymize your browsing you would want to install a virtual machine, have it permanently connected to a vpn, and never log into any pre-existing accounts.

If it *actually* were, people would get really bored after about 1 minute of readin' it and just give up.

You jest but I have read that upping your privacy game is actually a good way to invite additional scrutiny.

Dave may be right, and so may jdc.

But what if you have an idea that's not innocuous, not boring, or—perish the thought—even imaginative? You want to broadcast your concept to the universe?

The fat cats live in gated estates and you can bet your bottom peso they are as encrypted as they can possibly arrange.

PGP and other public key cryptography systems have two sets of keys, one public, and one private, so that sender and receiver do not have to exchange keys.

[gpgtools.org]

PGP even had a product called PGPfone, which allowed you to make secure phone calls, but it was too far ahead of its time, since it was developed before most people had broadband access.

macphanatic's remark:

"Date: October 10, 2017 07:53PM

seems to imply that VPN somehow "secures" email without encryption IF, and only if, they use the same server. Is that so?
