To set up Pidgin-GPG for secure chatting, you must configure Pidgin to use OpenPGP encryption through a dedicated plugin. This routes your instant messaging through the standard Web of Trust (WoT) infrastructure. Prerequisites
Before configuring Pidgin, you must install the software dependencies and generate a cryptographic keypair:
Install GnuPG: Download and install GnuPG (or Gpg4win for Windows).
Generate a Key: Open your terminal or a GUI key manager like Kleopatra to create your public/private keypair.
Ensure Agent is Running: Verify that gpg-agent is actively running to manage your keypassphrase. Step 1: Install the Pidgin-GPG Plugin
You will need to fetch and move the plugin binaries into Pidgin’s local repository: On Linux (Arch/Ubuntu/Debian) Arch Linux: Install via the AUR: yay -S pidgin-gpg-git Use code with caution.
Ubuntu/Debian: Install via compilation or your package manager:
sudo apt install libgpgme-dev libpurple-dev # Clone and build segler-alex/Pidgin-GPG from GitHub make && sudo make install Use code with caution. On Windows
Download the compiled pidgin-gpg.dll file from the repository.
Open your File Explorer and navigate to your roaming directory: %APPDATA%.purple\plugins</code>. Drop the .dll file directly into that folder. Step 2: Enable the Plugin in Pidgin Launch Pidgin. Click Tools in the top menu bar, then select Plugins.
Scroll through the list until you locate GPG/OpenGPG or Pidgin-GPG. Check the box next to the plugin name to activate it. Step 3: Configure Your GPG Keys
With the plugin highlighted in the Plugins menu, click Configure Plugin at the bottom. Select your chat account from the dropdown menu.
Assign your specific GPG Key ID or fingerprint to that account. Save your changes and close the plugin window.
Restart Pidgin completely to trigger the gpg-agent passphrase prompt. Step 4: Map Your Contacts Install :: Pidgin, the universal chat client
