Improve your Privacy with DNSCrypt

As of May 2023, roughly 94% of all traffic through Google’s servers is now encrypted. That’s a great win for internet privacy, unfortunately your browsing history can still be compromised via your DNS requests.

What is DNS?

DNS is an acronym for Domain Name System. In the simplest terms, it is like a contact list for website domains.

Most websites are https, isn’t that private?

Yes it is! but unfortunately DNS is not… Microsoft, Google, and Mozilla (Firefox) are creating encrypted versions of DNS, but it is not currently mainstream just yet. What does this mean for you? Well, every website you visit can potentially be logged by your ISP, or that free wifi network in your favorite cafe…


DNSCrypt solves this problem, by encrypting all your DNS requests, and optionally sending all requests through anonymous relays.

Setting up DNSCrypt on macOS

So, lets quickly get DNSCrypt up and running, you’ll need to dig into somewhat. But’s it’s not at all difficult, and will vastly improve your internet privacy

Install HomeBrew

Homebrew is a package manger for macOS, which simplifies the installation of DNSCrypt, as well as many other packages. First things first, open up, you can find it in your Applications\Utilities folder. Now copy and paste the following command to the Terminal window, and press enter:

/bin/bash -c "$(curl -fsSL"

Follow the prompts to finish installation, which will take some time depending on your internet connection speed. When complete, you will see an Installation successful! message.

Install dnscrypt-proxy

dnscrypt-proxy is the command line tool we are going to install to use DNSCrypt. With homebrew, its super easy to install. Copy the following command to your Terminal window, and press enter:

brew install dnscrypt-proxy

When installation has completed, we need to start the tool. You’ll need to enter your password after pressing enter.

sudo brew services start dnscrypt-proxy

Change macOS DNS settings

The final step is to change the DNS settings for your Mac, this is also super quick and easy:

  • Open System Preferences
  • Click on the Network icon
  • Select your Network Device, most likely Wi-Fi or Ethernet, the one on the top of the list, the one currently in use.
  • Click the Details... button
  • Open the DNS tab.
  • Add to the top of the list. *You can choose to also remove all other entries, to ensure that macOS doesn’t fallback to the other DNS servers in the case that DNSCrypt fails to resolve.
  • If you want to keep a fallback DNS server, you can add CloudFlares public DNS below *this is totally optional (I have 2 fallback servers in the screenshot below)
  • Click on the OK button

That’s it, your DNS requests are now all encrypted!

Anonymized DNS for enhanced privacy

Anonymized DNS is an optional new security feature of DNSCrypt which improves your privacy by anonymizing, and encrypting all your DNS queries. It’s also super easy to setup, we just need to edit the dnscrypt-proxy configuration file (located here: /opt/homebrew/etc/dnscrypt-proxy.toml) and restart dnscrypt-proxy. It’s not as difficult as it sounds!

  • Paste the following command into your terminal window, and press enter:
open -a TextEdit /opt/homebrew/etc/dnscrypt-proxy.toml
  • The configuration file will open in TextEdit.
  • Open another blank Text Edit file, to create your routes
  • Now, choose some relays from the following github page, one’s located closer to your actual location will give be slightly quicker. Heres a sample of what we need, change the values of the relays inside the [] square brackets. For example you could use the following 3: 'anon-cs-de2', 'anon-cs-nl', 'anon-ams-nl':
routes = [
    { server_name='*', via=['anon-cs-berlin', 'anon-cs-de', 'anon-cs-nl'] }

You can keep the server name as * so that the anonymized relays are used on all domains.

  • Now go back to the TextEdit file and search for [anonymized_dns], directly below this line - copy and paste your routes you just configured. Your configuration file will now look something like this:
routes = [
    { server_name='*', via=['anon-cs-berlin', 'anon-cs-de', 'anon-cs-nl'] }
  • Save and close the configuration file.
  • All thats left to do now, is restart dnscrypt-proxy:
sudo brew services restart dnscrypt-proxy


All your DNS requests should now be encrypted (and optionally, anonymized!) through DNSCrypt.
