Note : Wine n’a pas de support USB, donc le certificat USB ne sera pas reconnu… Ceci est donc inutile.

Nous utiliserons une toolbox avec Fedora pour installer le logiciel compagnon en utilisant Wine afin de faire fonctionner LiberSign.

• Lire la documentation

• Installer l'extension

• Télécharger libersign.exe

• Créer une toolbox wine :

    toolbox create -c app-wine
    toolbox enter -c app-wine
    sudo dnf install zsh wine
  

• Installer libersign.exe dans la toolbox :

    wine ./libersign.exe
  

  LiberSign est installé dans ~/.wine/drive_c/users/$(whoami)/Local\ Settings/Application\ Data/LiberSign/

• Créer un manifest ~/.mozilla/native-messaging-hosts/org.adullact.libersign.json :

    {
      "name": "org.adullact.libersign",
      "description": "Chrome Native Messaging LiberSign Extension",
      "path": "/home/mildred/.mozilla/native-messaging-hosts/org.adullact.libersign.sh",
      "type": "stdio",
      "allowed_extensions": [
        "@libersign"
      ]
    }
  

• Créer le script /home/mildred/.mozilla/native-messaging-hosts/org.adullact.libersign.sh :

    #!/bin/sh
  
    set -e
    passthrough=false
    passthrough_out=true
