SSL DSM

Is there any development on a SSL based DSM? It would be nice to have another option in securing VNC connections. In my office, it would be a perfect solution to turn on SSL tunnelling without having to worry about exchanging keys. ZeBeDee is too much of a hassle. A SSL DSM would be an excellent option.

The current DSMPlugin design does not support some needed elements to support SSL development, like direct access to the sockets and/or ability to negotiate a key.

The ZVNC page (http://home.comcast.net/~davedyer/znc/zvnc.html) makes a good point... ZeBeDe is now available as a library. Is there any chance at it being incorporated into UltraVNC?

Most likely not. The Ultra team has made it clear that they want to stay far away from any issues with legal issues exporting crypto software. The MSRC4Plugin uses the crypto functionality built-in to Windows, so there isn't actually any crypto code involved.

The ZeBeDee library *could* be incorporated into Ultra, but don't expect to see it with the official distribution.

Someone could perhaps make a DSM using ZeBeDeeLib...

Please see these for the reasons as to why not:

The MSRC4Plugin is as close to "SSL" as I can get it at the moment.

SSL uses RC4 128Bit encryption, with dynamically exchanged keys.

MSRC4Plugin uses RC4 encryption (40-128Bit) with pre-shared keys. (some Win95 machines only support 40Bit...)

Currently the DSM Plugin architecture in UltraVNC does not support dynamic key exchange. I've asked for it. Its on the TODO list. Nothing yet though...
