encrypted-dns-configs

Configuration profiles for DNS over HTTPS and DNS over TLS. Check out the article for more info: paulmillr.com/posts/encrypted-dns/ and info about contributing a new profile.

Caveats

DoH seems to work faster & better than DoT judging from the Google's article.

Starting from iOS & iPadOS 15.5, Wi-Fi captive portals in cafes, hotels, airports are exempted by Apple from eDNS rules; to simplify authentication. This is good news. There are still some other issues; we can't fix them, only Apple can:

• eDNS gets disabled: Little Snitch & Lulu, VPN
• Some traffic is exempt from eDNS: Terminal / App Store, Chrome

If you need even more privacy, check out encrypted-dns over TOR.

Providers

Censorship=yes means the profile will not send true information about hostname=IP relation for some hosts.

Installation

To make settings work across all apps in iOS, iPadOS & macOS, you'll need to install configuration profile. This profile would tell operating system to use DoH / DoT. Note: it's not enough to simply set server IPs in System Preferences — you need to install a profile.

iOS / iPadOS: Open the mobileconfig file in GitHub by using Safari (other browsers will just download the file and won't ask for installation), and then click/tap on "Allow" button. The profile should download. Go to System Settings => General => VPN, DNS & Device Management, select downloaded profile and tap the "Install" button.

macOS (official docs):

1. Download and save the profile. After save, rename it to be in format: NAME.mobileconfig, not NAME.txt, or so

2. Choose Apple menu > System Settings, click Privacy and Security in the sidebar, then click Profiles on the right. (You may need to scroll down.) You may be asked to supply your password or other information during installation.

3. In the Downloaded section, double-click the profile.

4. Review the profile contents then click Continue, Install or Enroll to install the profile.

   If an earlier version of a profile is already installed on your Mac, the settings in the updated version replace the previous ones.

Scope

There seems to be an additional option that allows to use system-wide profiles. To try it, add this to mobileconfig file:

<key>PayloadScope</key>
<string>System</string>

Signed Profiles

In the signed folder we have signed versions of the profiles in this repository. These profiles have been signed by @Xernium so that when you install the profiles, they will have a verified check box on the installation screen. It also ensures that these profiles have not been tampered with. However, since they were signed by a third party, they may lag behind their unsigned counterparts a little. The signature is valid until 2024-11-30

Previous signature by: @Candygoblen123, replaced at 2023-11-29

To verify resolver IPs and hostnames, compare mobileconfig files to their documentation URLs. Internal workings of the profiles are described on developer.apple.com. In order to verify signed mobileconfigs, you will need to download them to your computer and open them in a text editor, because signing profiles makes GitHub think that they are binary files.

Contributing a new profile

Profiles are basically text files. Copy an existing one and change its UUID, make sure you update README with new profile's info.

In addition to generating online, there are many other ways to generate a random UUID:

• Press F12 to open DevTools in the browser, run this code in the console

crypto.randomUUID();

• Run these commands in the macOS / Linux terminal

# Works both in macOS & Linux
uuidgen

# Works in Linux
cat /proc/sys/kernel/random/uuid

• Run this cmdlet in Powershell

New-Guid
