    OMEMO with profanity.

    Hello OMEMO!

    OMEMO needs crytographic materials. You can generated this crytographic materials via /omemo gen . If you have more than one device, make sure you are trusting your other devices. Check your fingerprints via /omemo fingerprint . You may wont trust all your devices:

    /omemo trust <Your XMPP-ID> <Your fingerpint>
    

    Check the fingerprint of your buddy. List the fingerprints of your buddy via

    /omemo fingerprint <XMPP-ID of your buddy>
    

    Check the fingerprints with you buddy over a secure medium (phone or singed OpenPGP message) and trust the buddy’s fingerprint via the command:

    /omemo trust <Buddy's XMPP-ID> <Buddy's fingerpint>
    

    You can start a OMEMO Session via the omemo-start command /omemo start <buddy's XMPP-ID> .

    Debugging

    Get the device list of your Buddy. Change the to and the from tag of the line shown below.

    <iq type='get' from='your@domain.tld' to='buddy@domain.tld' id='getOmemoDeviceList'><pubsub xmlns='http://jabber.org/protocol/pubsub'><items node='eu.siacs.conversations.axolotl.devicelist'/></pubsub></iq>
    

    Use the /xmlconsole to open the XMP Console Window and sent those line to your server.

    The Server should return a result of the iq with id getOmemoDeviceList . There should be a item -Tag with the id current followed by a list of device id.

    <items node="eu.siacs.conversations.axolotl.devicelist">
    	<item id="current">
    	<list xmlns="eu.siacs.conversations.axolotl">
    	<device id="174235744"/>
    	<device id="71071234"/>
    	<device id="22318128"/>
    	</list>
    	</item>
    </items>
    

    The known devices and fingerprints are stored in ~/.local/share/profanity/omemo/<account>/known_devices.txt . The trust information are stored in ~/.local/share/profanity/omemo/<account>/trust.txt .
