Install the Plugin with the Gajim PluginManager. You need Gajim
version 0.16.6 or higher. If your package manager does not provide an up to date version
you can visit gajim.org for further install instructions.
Restart Gajim, and activate OMEMO in Gajims PluginManager
Enable OMEMO Multi-End Message and Object Encryption in the Plugin-Manager.
If your contact supports OMEMO you should see a new orange fish icon in the chat window.
Encryption will be enabled by default for contacts that support OMEMO.
If you open the chat window, the Plugin will tell you with a green status message if its enabled or disabled.
If you see no status message, your contact doesnt support OMEMO.
(Beware, every status message is green. A green message does not mean encryption is active. Read the message !)
You can also check if encryption is enabled/disabled, when you click on the OMEMO icon.
When you send your first message the Plugin will query your contacts encryption keys and you will
see them in a readable fingerprint format in the fingerprint window which pops up.
you have to trust at least one fingerprint to send messages.
you can receive messages from fingerprints where you didnt made a trust decision, but you cant
receive Messages from not trusted fingerprints
