UltraVNC 1.1.0.0 beta + SecureVNC Plugin 2.3 did not work

Post by esc-ctrl »

I am using UltraVNC 1.1.0.0 beta + SecureVNC Plugin 2.3.0.0

When I use UltraVNC 1.0.9.6.2 + SecureVNC Plugin, it works all great!
-> I have no problems to set up a Server and Viewer with SecureVNC Plugin and encryption and so on...

When I use UltraVNC 1.1.0.0 + SecureVNC Plugin, it would not work.

My problem:
When I set a passphrase in the SecureVNC Plugin and want to connect with the UltraVNC Viewer to the UltraVNC Server it would not work -> Status from the UltraVNC Viewer: Password requested and the pop-up window to enter the VNC Authentication DID NOT pop up and 100% CPU usaged from the UltraVNC Viewer process.

What I found out:
When the passphrase is empty, it works.
When I use UltraVNC Server 1.0.9.6.2 and the UltraVNC Viewer 1.1.0.0, it works but the UltraVNC Viewer tell me it not secure and can be hacked.
When I use UltraVNC Server 1.1.0.0 and the UltraVNC Viewer 1.0.9.6.2, it works -> the pop up window to enter the VNC Authentication pop up -> I enter the passphrase -> UltraVNC Viewer tells me: UltraVNC Server requires a higher UltraVNC Viewer version -> clear! I just do it for testing.

So why it works without passphrase?
So why it works with UltraVNC Server 1.1.0.0 and UltraVNC Viewer 1.0.9.6.2?
So why it DOES NOT WORKS with UltraVNC Server 1.1.0.0 and UltraVNC Viewer 1.1.0.0?

Thanks for reply

Checking, it seems that I also need to replace the old passphrase method.
Using the passphrase as part of the key isn't secure, can be brute forced hacked.

Bug will be solved for relaese.
