java viewer and dsm plugin - why can use ?

[remotepc]

Hi ALL,

first of all many many thanks for the fix made in new release . Hats off to efforts made by you guys .

I am a c++ network programmer , and don't know java . Please help me in this regard .

I am curious to know that what are the limitations in using RC4 key encryption with java viewer . while searching on ultravnc forum I found that one issue is to use crypto api in java , but I think that can be supported by java native code calls , their might be library in java to support advpi .

If the issue is sending Rc4 key file then this can be achieved by negotiating this file via repeater which applet can download and use .

Please guide me in this regard .As I think you people would have already analyzed all these things . Please tell me what are the limitations in using rc4 key encryption with java viewer .

Thanks in advance .

Regards
manu

Response from Ultrasam:-

Hi,

Rudi forwarded me your question about RC4 in the JavaViewer.

The answer is yes: if a java RC4 implementation can be found, it is possible to add a class to the javaviewer that mimics the MSRC4 plugin behavior.

As you say, the main problem is the encryption key file, but it can be avoided by skipping the use of a key file on server side: in this case the VNC password + salt is used to generate a hash that is used as the encryption key.
This behavior is already implemented in the MSRC4plugin (no key file => use a VNC password hash as crypto key)
