On this page, we collect information on how to use with different OpenPGP software products.
We are still in the process of adding more. If you are missing some, please write to us and we'll try to add it.


Enigmail for Thunderbird uses by default since version 2.0.12.

Full support is available since Enigmail 2.1 (for Thunderbird 68 or newer):

GPG Suite

GPG Suite for macOS uses by default since August 2019.


OpenKeychain for Android uses by default since July 2019.

Note that there is no built-in support for upload and e-mail verification so far.


To configure GnuPG to use as keyserver, add this line to your gpg.conf file:

keyserver hkps://

Retrieving keys

Uploading your key

Keys can be uploaded with GnuPG's --send-keys command, but identity information can't be verified that way to make the key searchable by e-mail address (what's that?).


Usage via Tor

For users who want to be extra-careful, can be reached anonymously as an onion service. If you have Tor installed, use the following configuration:

keyserver hkp://zkaan2xfbuxia2wpf7ofnkbz6r5zdbbvxbunvp5g2iebopbfc4iqmbad.onion


We offer an API for integrated support in OpenPGP applications. Check out our API documentation.
