### Privileged App Extensions
|
||||
Android 12 comes with special support for seamless app updates with [third party app stores](https://android-developers.googleblog.com/2020/09/listening-to-developer-feedback-to.html). The popular Free and Open Source Software (FOSS) repository [F-Droid](https://f-droid.org) doesn't implement this feature and requires a [privileged extension](https://f-droid.org/en/packages/org.fdroid.fdroid.privileged) to be included with the Android distribution in order to have unattended app installation.
|
||||
|
||||
GrapheneOS doesn't compromise on security; therefore, they do not include the F-Droid extension. Users have to confirm all updates manually if they want to use F-Droid. Alternatively, they can use the Droid-ify client which does support seamless app updates in Android 12. GrapheneOS officially recommends [Sandboxed Google Play](https://grapheneos.org/usage#sandboxed-google-play) instead. Many FOSS Android apps are also in Google Play but sometimes they are not (like [NewPipe]({% link _evergreen/video-streaming.md %})).

Once you add your server, that’s it! In the Outline clients it’s just a matter of pressing “Connect”, and all your traffic will be proxied through your server! You can use this connection to keep your traffic safe when you’re on public WiFi networks, or just to keep your browsing hidden from your ISP.

### Conclusion
|
||||
That should be all you need to get your very own VPN up and running! **Do not share your access key with anyone**, this is the key starting with `ss://`. If you want to grant other users access to your server, click “Add a new key” in Outline Manager and give them a new, unique key. If you share a key, anyone with knowledge of that key will be able to see all the traffic of anyone else using the key. It should go without saying, but don’t send people keys over unencrypted channels: No Facebook Messenger, no emails. Stick with [Signal, Wire, or Briar]({% link _evergreen/real-time-communication.md %}) if you don’t have a secure app already.

|
||||
With Outline, there is no need to worry about the security of your server. Everything is set to automatically update with no intervention required! Another thing to note: The port on your Outline server is randomly generated. This is so the port can’t be easily blocked by nation/ISP level censors, however, this VPN may not function on some networks that only allow access to port 80/443, or on servers that only allow traffic on certain ports. These are edge-cases, but something to keep in mind, and if they apply you may need to look for more technical options.

DNS has existed since the [early days](https://en.wikipedia.org/wiki/Domain_Name_System#History) of the Internet. DNS requests made to and from DNS servers are **not** generally encrypted.

Unencrypted DNS requests are able to be easily **surveilled** and **modified** in transit.

As the DNS protocol is not encrypted, the ISP (or any network operator) can use [deep packet inspection (DPI)](https://en.wikipedia.org/wiki/Deep_packet_inspection) to monitor requests. ISPs can also block requests based on common characteristics, regardless of which DNS server is used. Unencrypted DNS always uses [port](https://en.wikipedia.org/wiki/Port_(computer_networking)) 53 and always uses the [User Datagram Protocol (UDP)](https://en.wikipedia.org/wiki/User_Datagram_Protocol).

[**DNSCrypt**](https://en.wikipedia.org/wiki/DNSCrypt) was one of the first methods of encrypting DNS queries. The [protocol](https://en.wikipedia.org/wiki/DNSCrypt#Protocol) operates on [port 443](https://en.wikipedia.org/wiki/Well-known_ports) and works with both the [TCP](https://en.wikipedia.org/wiki/Transmission_Control_Protocol) or [UDP](https://en.wikipedia.org/wiki/User_Datagram_Protocol) transport protocols. DNSCrypt has never been submitted to the [Internet Engineering Task Force (IETF)](https://en.wikipedia.org/wiki/Internet_Engineering_Task_Force) nor has it gone through the [Request for Comments (RFC)](https://en.wikipedia.org/wiki/Request_for_Comments) process, so it has not been used widely outside of a few [implementations](https://dnscrypt.info/implementations). As a result, it has been largely replaced by the more popular [DNS over HTTPS (DoH)](/dns/#dns-over-https-doh).

[**DNS over TLS (DoT)**](https://en.wikipedia.org/wiki/DNS_over_TLS) is another method for encrypting DNS communication that is defined in [RFC 7858](https://datatracker.ietf.org/doc/html/rfc7858).

Preference in the industry has been moving away from DoT to [DNS over HTTPS](/dns/#dns-over-https-doh) in recent years as DoT is a [complex protocol](https://dnscrypt.info/faq/) and has varying compliance to the RFC across the implementations that exist. DoT also operates on a dedicated port 853 and that can be blocked easily by restrictive firewalls.

When we do a DNS lookup, it's generally because we want to access a resource. Below, we will discuss some of the methods that may disclose your browsing activities even when using encrypted DNS:
|
||||
|
||||
### IP Address
|
||||
The simplest way to determine browsing activity might be to look at the IP addresses your devices are accessing. For example, if the observer knows that `privacyguides.org` is at `198.98.54.105`, and your device is requesting data from `198.98.54.105`, there is a good chance you're visiting Privacy Guides.

||||
This method is only useful when the IP address belongs to a server that only hosts few websites. It's also not very useful if the site is hosted on a shared platform, (e.g. Github Pages, Cloudflare Pages, Netlify, Wordpress, Blogger etc). It also isn't very useful if the server is hosted behind a [reverse proxy](https://en.wikipedia.org/wiki/Reverse_proxy), which is very common on the modern Internet.

|
||||
|
||||
### Server Name Indication (SNI)
|

Server Name Indication, is typically used when a IP address hosts many websites. This could be a service like Cloudflare, or some other [Denial-of-service attack](https://en.wikipedia.org/wiki/Denial-of-service_attack) protection.

||||

||||
|
||||
This means even if we are using "Encrypted DNS" servers, the domain will likely be disclosed through SNI. The [TLS v1.3](https://en.wikipedia.org/wiki/Transport_Layer_Security#TLS_1.3) protocol brings with it [Encrypted Client Hello](https://blog.cloudflare.com/encrypted-client-hello/) which prevents this kind of leak.

||||
Another way your browser can disclose your browsing activities is with the [Online Certificate Status Protocol](https://en.wikipedia.org/wiki/Online_Certificate_Status_Protocol). When visiting a [HTTPS](https://en.wikipedia.org/wiki/HTTPS) website, the browser might check to see if the [X.509](https://en.wikipedia.org/wiki/X.509) [certificate](https://en.wikipedia.org/wiki/Public_key_certificate) has been [revoked](https://en.wikipedia.org/wiki/Certificate_revocation_list).

Apple does not provide a native interface for creating encrypted DNS profiles. [Secure DNS profile creator](https://dns.notjakob.com/tool.html) is an unofficial tool for creating your own encrypted DNS profiles, however they will not be signed. Signed profiles are preferred; signing validates a profile's origin and helps to ensure the integrity of the profiles. A green "Verified" label is given to signed configuration profiles. For more information on code signing, see [About Code Signing](https://developer.apple.com/library/archive/documentation/Security/Conceptual/CodeSigningGuide/Introduction/Introduction.html).

### Linux

`systemd-resolved` doesn't [yet support](https://github.com/systemd/systemd/issues/8639), which many Linux distributions use to do their DNS lookups. This means you need to install a proxy like [dnscrypt-proxy](https://github.com/DNSCrypt/dnscrypt-proxy) and [configure it](https://wiki.archlinux.org/title/Dnscrypt-proxy) to take all the DNS queries from your system resolver and forward them over HTTPS.

## Encrypted DNS Proxies
|
||||
This software provides third-party encrypted DNS support by pointing the [unencrypted dns](/dns/#unencrypted-dns) resolver to a local [encrypted dns](/dns/#what-is-encrypted-dns) proxy.
|
||||
Encrypted DNS proxy software provides a local proxy for the [unencrypted DNS](/dns/#unencrypted-dns) resolver to forward to. Typically it is used on platforms that don't natively support [encrypted DNS](/dns/#what-is-encrypted-dns).

OpenPGP also does not support [forward secrecy](https://en.wikipedia.org/wiki/Forward_secrecy), which means if either your or the recipient's private key is ever stolen, all previous messages encrypted with it will be exposed. [How do I protect my private keys?](/providers/email/#email-encryption)
