I am trying to use the new security property KeyData to pass the RC4 key to the client without the need of an external file, but I can't seem to get the syntax correct. I have truncated the HEX version of the key because obviously I don't want that to show up in a forum post.Am I entering the key properly? Should there be a space in between every HEX char? I was also struggling on how to convert the key generated by VNC to a format usable by this ActiveX. I found an online converter that changed the text string from the file into a HEX format. Should this work? Is there a better to get a HEX string out of that file? Can someone show me the correct syntax to define this property in HTML? <HTML>

UVNCS_KeyData expects SAFEARRAY of bytes and in your code your are passing a string to it. There is a VBscript function that allows to convert sting to SAFEARRAY of bytes. Sorry I'm not so good at VBscript so I cannot tell you exactly which method you should use, but if you google for it you sure will be able to find it.
Otherwise you might want to use UVNCS_KeyDataAsHexStr property instead. It accepts RC4 key if form of string of HEX values.

Can I see a code example showing the syntax on passing a HEX value into the UVNCS_KeyDataAsHexStr property? Nothing I have tried is working.
