The underlying connection was closed Could not establish trust relationship for the SSL/TLS secure channel.

Please let me know

Which version of the client object model - EMCAScript (JavaScript) or the .NET managed client object model? –  Ryan Feb 28 '12 at 12:26

Hope it helps. http://blogs.msdn.com/b/sridhara/archive/2010/10/19/working-with-sharepoint-2010-client-object-model-on-an-ssl-enabled-site.aspx

UPDATE: So you doesn't work in the browser context. As I understand these things when your code works in the browser context and on the SSL-enabled page the browser automatically add a certificate to each your request because for SSL to work the both sides (the client and the server) need to use a certificate. If you create a request to SSL-enabled resource manually outside the browser you need to supply the certificate youself. The *.cer file is the certificate saved to file. You can use simple self-signed certificate. There are several tools to create such a certificate. The code example shows how to add a certificate from the *.cer file to each your request from the managed client object model in SharePoint.

what does it mean from the above url: (where it has this) X509Certificate cert = X509Certificate.CreateFromCertFile(@"d:\test.cer"); –  RHM Feb 28 '12 at 16:40

Let's accurate the details - what version of client object model do you use? Javascript? Silverlight? Managed? –  Alex Boev Feb 28 '12 at 16:44
    
Managed one I am using. –  RHM Feb 28 '12 at 17:09
