Disabling OTR in Spark

Version 2

    How I can disable OTR in Spark?

     

    OTR is an encrypted comminucation between two clients that is based on personal certificates. It has a high level of encryption and con not the read by anyone else that the two partners. In a corporate environment, this might be problematic for compliance/legal reasons since companys might be required to document internal discussions (SOX compliance, Anti trust regulation etc.).

     

     

    There are two ways to disable it:

     

    1. Repackage Spark to prvent the distribution of the OTR plugin
    2. Disable the negotiation of the OTR connection between two clients.

     

     

    • Packet-filtering, or content-filtering, rather, is how I've disabled OTR for my users. It's pretty simple:
      Go to Server -> Server Settings -> Content Filter.  Set your pattern to "\?OTR" and enable the filter.
      Users attempting to enable OTR chat will see it trying to initialize and it will timeout after 10 seconds.
