Integrate with other applications

[dashohoxha]

Try to integrate with other applications, for example with one or more file managers, one or more mail clients, LibreOffice, etc.

• File managers can have the ability to encrypt/decrypt and sign/verify files from their context menu or other menus.
• Email clients can have the ability to encrypt/decrypt and sign/verify the emails. Some of them do have it, some others don't, or it is not so easy or user-friendly.
• Office applications can sign/verify the documents.
• Etc.

This is an open task and optional. Try to complete some parts of it if there is still some available time before the end of the project. Continue working on it after the project is closed, if you wish.
