Create Mailvelope, with install instructions and how to use with GPG

New page

Mailvelope is a browser extension for using PGP-based end-to-end encryption with webmail clients

== Installation ==
Mailvelope can be installed manually from [https://addons.mozilla.org/en-US/firefox/addon/mailvelope/ Firefox Add-ons] or the [https://chromewebstore.google.com/detail/mailvelope-secure-your-em/kajibbejlbohfaggdiogboambcijhkke Chrome Web Store].

=== Via Home-Manager ===
Many Firefox add-ons are packaged in the [[Nix User Repository]], in [https://nur.nix-community.org/repos/rycee/ rycee's repo].

This allows you to install them declaratively:<syntaxhighlight lang="nix">
{ pkgs, ... }: {
# Change to your browser
programs.librewolf = {
profiles.<profile-name> = {
extensions.packages = with pkgs.nur.repos.rycee.firefox-addons; [
mailvelope
];
};
};
}
</syntaxhighlight>

== Usage ==

=== Using with GnuPG ===
Mailvelope supports using your system's [[GnuPG]] rather than the built-in `OpenPGP.js`.

To allow communication between mailvelope and GnuPG, it must be allowed via native messaging hosts.

To allow it for Firefox-based browsers, add this to your Home Manager configuration:<syntaxhighlight lang="nix">{ pkgs, lib, ... }: {
# Change to your browser
programs.librewolf = {
nativeMessagingHosts = with pkgs; [
# for mailvelope
(writeTextDir "lib/mozilla/native-messaging-hosts/gpgmejson.json" ''
{
"name": "gpgmejson",
"description": "JavaScript binding for GnuPG",
"path": "${lib.getExe' pkgs.gpgme.dev "gpgme-json"}",
"type": "stdio",
"allowed_extensions": ["jid1-AQqSMBYb0a8ADg@jetpack"]
}
'')
];
};
}</syntaxhighlight>Or to your NixOS configuration via {{nixos:option|programs.firefox.nativeMessagingHosts.packages}}.

The json is based on the [https://github.com/mailvelope/mailvelope/wiki/Creating-the-app-manifest-file-on-macOS-and-Linux#firefox upstream recommendation]
