LocalPGP

About

Allows using local gnupg installation from the system via `gpgme-json`.

### Installing gpgme-json on your system

**Debian/Ubuntu:**
```bash
sudo apt install gpgme-json
```

**Fedora:**
```bash
sudo dnf install gpgme
```

**Arch Linux:**
```bash
sudo pacman -S gpgme
```

Verify installation:
```bash
which gpgme-json
# Should output: /usr/bin/gpgme-json
```

### Install Native Messaging Host for Chrome/Chromium

Native messaging allows the browser extension to communicate with `gpgme-json` on your system.

Create the configuration file at `~/.config/chromium/NativeMessagingHosts/gpgmejson.json` (for Chromium) or `~/.config/google-chrome/NativeMessagingHosts/gpgmejson.json` (for Chrome):

```bash
mkdir -p ~/.config/google-chrome/NativeMessagingHosts/
cat > ~/.config/google-chrome/NativeMessagingHosts/gpgmejson.json << 'EOF'
{
  "name": "gpgmejson",
  "description": "Integration with GnuPG",
  "path": "/usr/bin/gpgme-json",
  "type": "stdio",
  "allowed_origins": [
    "chrome-extension://ckgehekhpgcaaikpadklkkjgdgoebdnh/"
  ]
}
EOF
```
