Gnutls-win32-msvc.tgz contains (modified) source files taken out of realvnc, libgpg-error, libgcrypt and gnutls sources. Add gnutls.lib as library for all executables.Add the directory gnutls/gnutls out of the GNUTLS build tree to the include path to each subproject.Add the definitions HAVE_GNUTLS to each subproject.vnc-tls-winbuild.patch should contain all changes to the project files: Apply vnc-tls-win.patch and vnc-tls-sectypes.patch.Then copy all cxx and h files out of tlsvnc.tgz to the common directory (common/rdr and common/rfb, depending on the.Copy the directory gnutls/gnutls out of the GNUTLS build tree into the win directory.Open the work space and compile the gnutls.lib project (gnutls - Win32 Release).

Unpack gnutls-1.2.4.tar.bz2 in the same directory.Unpack libgcrypt-1.2.1.tar.gz in the same directory.Unpack libgpg-error-1.0.tar.gz in the same directory.Working, but other functions (like network IO) will not work: I managed to get all need features of GNUTLS under MS Visual C++ 6

Then build the java viewer.Р”Р‡or the windows version, GNUTLS must be compiled first.

To enable the TLS support, pass the parameter -enable-gnutls to configure.Р”Р‡or the java viewer, unpack the java sources, copy all java files out of vnctls.tgz to common/rfb and apply the Then copy all cxx and h files out of tlsvnc.tgz to the common directory (common/rdr and common/rfb, depending on the To compile the unix version, unpack the unix sources, apply the patches vnc-tls-unix.patch, vnc-tls-build.patch and vnc-tls-sectype.patch. As a fix add SendMessage(handle,WM_PAINT,0,0) after the call of InvalidateRect in DesktopWindow::invalidateDesktopRect (win/vncviewer/DesktopWindow.cxx).Р”Р„ll source files (and patches) are contained in tlsvnc.tgz.Р”Р„dditionally you need realvnc free edition 4.1.1 (4.1 for Java) from RealVNC.

Windows viewer delays in some situations screen updates, until a key is pressed.

TLS in the Windows server can only be enabled using the Registry or command line parameter SecurityTypes.

The Java Viewer runs only on a Sun JRE 1.4.2 or later.

Certificates with more than 1024 Bit are not supported by the SUN JRE.

The Java Viewer does not verify the server certificate.

More checks for the server certificate are needed (eg.

X509None/Plain/Vnc show no useful data, if it asks the user, if he wants to abort.

X509Plain authentication like Plain with encryption like X509None.

X509Vnc standard VNC authentication with encryption like X509None.

To generate X509Р”В¬ertificates, use openssl or a frontend like TinРµСљСљA. The server certificate fails, a cryptic error message is shown and the user is asked, if he wants to abort. The unix and windows viewerР”Р„ccept the command line parameter x509ca and x509crl to specify optionally the certificate of the CA to verify against. The key and certificated are specified using the x509cert and x509key command line parameter in the server. The identity of the server is verified using X509 certificates.

X509None no authentication, data is encrypted using GNUTLS.

TLSPlain authentication like Plain with encryption like TLSNone.

TLSVnc standard VNC authentication with encryption like TLSNone.

The identity of the server is not verified.

TLSNone no authentication, data is encrypted using GNUTLS.

Additionally the number of supported security types in the viewer would have to be raised.

#VNC VIEWER FREE EDITION FOR WIN32 PASSWORD#

Security type is not activated (addSecType(secTypeVncPlain) is commented out), as it is insecure to transmitР”Р„ password without any encryption. Which accept username/password combinations, where the first character are equal. In the server, no verificationР”В¬ode for the username/password pair have been written, for testings purposes a disabled verificator exists,

Plain no encryptions, asks username and password.

VncAuth no encryption, standard VNC authentication.

The patches implement the following encryption/authentication methods for VNC: Important: RealVNC 4.1.1 (and therefore the TLS for VNC patches) can be forced to use any security type by the client. To realvnc version 4.1.1 and modified them so, that they are working under Unix, Windows and Java.Р”Р„s I introduced an additional byte before the TLS Handshake, I use other security types. I ported the patches from Mark McLoughlin for TLS support Provides built-in encryption in its commercial versions. The data is normally secured with SSH tunnels or VPN connections. VNC suffers from the problem, that it transmits its data not encrypted across the network.
