Created Issue: Difficulty getting IPAWSTester to work [18634]

Having a lot of difficulty getting the IPAWSTester application in your EDXLSharp_Tools solution to work. I have my certificate and the cog id/user id info all correct. I can ping, and i can run your 'getmessage' methods. But the postCAP method is giving me a lot of issues.
I'm using the sample CAP data you provide in https://edxlsharp.codeplex.com/wikipage?title=CAP%20Sample%202&referringTitle=XML%20Examples
First, the XML would error out because it needs 'IPAWSv1.0' as a 'code' value. So i added that to the XML. Secondly, it errored out because it didn't like the polygon values you were using. So i just deleted those right now.

Now finally i've reached the SignXML procedure in the IPAWS_CAP12Proxy class. I error out at signedXML.ComputeSignature with the error:
{"Invalid algorithm specified.\r\n"}
See the stack trace below if it helps. Any guidance on how to move past this issue? I'm using the latest download as of today from your source code.
