SC 1431
Use https://support1.uvnc.com/cgi-bin/upload12.pl to generate SC 2.0
Zip can contain (SC_Server_ClientAuth.pubkey, helpdesk.txt SC_20.ini background.bmp logo.bmp)
1) Start normal winvnc.exe, select encryption SecureVNCPlugin.dsm and generate keys.
rename pubkey to SC_Server_ClientAuth.pubkey and viewer key to SC_Viewer_ClientAuth.pkey
2) Upload zip and download SC
3) Run vncviewer (make sure the viewer key is in the same folder), select encryption and start listener
The sample use the localhost, so server connect to viewer running on the same host (replace localhost in helpdesk.txt to connect to a real external host)
Check helpdesk.txt and SC_20.ini in sample to see how to add it.

https://www.uvnc.eu/download/1400/SC_Vi ... tAuth.pkey
Replace the keys by your own, private key is now public... Only for testing.
