    This suggestion only works if I turn off encryption in my Enterprise RealVNC Server (Configure->Options->Encryption->Prefer Off).

    However, I would like to use encryption.  Will this be available in a future release of JumpDesktop?

    Ryan, at this time we don't have plans to support RealVNC's encryption mechanism as RealVNC doesn't publish the specs for it's protocol. Jump does have it's own way to encrypt the connection if you use the automatic setup method (it uses SSL encryption).

    I ran across this 6 year old post after trying to connect to the 5.3.2 VNC server in Raspberry Pi 4.4.21.  Is the answer still accurate?

    Yes, it is if you're using RealVNC server: You'll need to enable password based authentication for RealVNC. The method to enable it might vary on the Pi. The steps above are only for the PC.

    Thanks, I did have to use a 6 character VNC password to get it to work.

    My company REQUIRES 128 bit encryption for VNC....is this supported now in 2017?

    Yes, encryption over VNC is supported. Are you connecting to a RealVNC server? If so, it uses proprietary encryption which NOT supported. The types of encryption supported for VNC are:

    1. VNC-over-SSH. Jump has a built in SSH client that can connect to target over SSH and then automatically create a forwarding to the VNC server.
    2. VNC-over-SSL. Modern VNC servers use standard TLS/SSL to encrypt the connection - Jump supports this.

    Kerry - are you connecting to a Windows or Mac machine? If so, the best / easiest way to connect it using Jump's automatic setup - it'll take care of encryption for you. On the machine you want to connect TO just visit https://jumpdesktop.com/go and follow the instructions there.

    If you're on Linux then shoot an email to support@jumpdesktop.com with details about your current configuration and we'll walk you through it.
