Connect ultra vnc repeater with secure plugin

[vant...@gmail.com]

Hello, I bought the pro version, however I need to use it with ultravnc repeater, until then, okay, I can connect however I need to use encryption, on the computers I use SecureVNCPlugin, I generated two keys, private and public for use,but I can not configure this in bVNC, is there any way to do it? And maintain compatibility with the framework I already have?

Hello,

The SecureVNCPlugin plugin has not received a single update in 9 years. There are no developer docs. There is no dev community, mailing list, or discussion forum. The author, Adam Walling, does not respond to any questions.

I would consider the plugin insecure at this point, and extending support for it involves reverse-engineering 9 year old C++ code with hardly any comments in it, no developer mailing list, no support forum, and no replies to my questions. I think that given there are better options out there, it's not worth spending the time on writing support for the plugin.

That is not to say that help from my community in reverse engineering the Secure Plugin protocol and writing the code for bVNC is not welcome!

Let me take the opportunity to mention some of the awesome alternatives to this plugin.

1) SSH tunneling. An OpenSSH server can be installed on practically any operating system including Linux, Mac OS X, Windows, and BSD. Even on Windows, it now comes as an official package published and maintained by Microsoft. The SSH option is an excellent replacement or addition to the repeater machine, since you can port forward to any number of VNC servers behind the SSH server.

2) VeNCrypt. This encryption method is supported by one or more VNC servers, including the cross-platform TigerVNC server.

I hope this is a good explanation.

Thanks!

Iordan

I'm sorry, my English sucks, I'm going to use the translator this time. Is it possible to use bVNC to connect to Ultravnc SC via Repeater? I can establish the connection, but there is no data transmission.

Hey guys,

Just wanted to let you know that I revisited the SecureVNCPlugin for UltraVNC recently and saw that it was included in the main UltraVNC project and is being maintained together with the server.

As a result,  in version v6.4.5 of bVNC (in Beta as of June 22, 2026), I have released support for all main features of SecureVNCPlugin for UltraVNC, including:

    - Support for all AES-based ciphers
    - SecureVNCPlugin Passphrase authentication
    - SecureVNCPlugin + MS-Logon 1 and 2 authentication as alternative to passphrase
    - Client key authentication
    - Client key generation and import
    - Best-effort connection in "Basic VNC" mode

Join the beta on Google Play, or install v6.4.5 from:

https://github.com/iiordanov/remote-desktop-clients/releases

or F-Droid repo:

https://android.izzysoft.de/repo/apk/com.iiordanov.freebVNC

Switch to "UltraVNC" for the Connection Type to see the full range of new options related to the feature.
