+Product: Mono: Class Libraries
+Version: 1.2
+OS: GNU/Linux [Other]
+OS Details: ubuntu
+Status: NEW   
+Priority: Normal
+Component: System.Security

+TargetMilestone: ---
+Summary: DSAManaged.ImportParameters throws an exception when importing a private key
+Description of Problem:
+DSAManaged.ImportParameters rejects keys with parameters.Y == null, so if
+you try to import a private-only key, there will be an exception.
+Steps to reproduce the problem:
+1. Compile and run attached test program
+Actual Results:
+Unhandled Exception: System.Security.Cryptography.CryptographicException:
+Error occured during a cryptographic operation.
+  at Mono.Security.Cryptography.DSAManaged.ImportParameters (DSAParameters
+parameters) [0x00000]
+  at System.Security.Cryptography.DSACryptoServiceProvider.ImportParameters
+(DSAParameters parameters) [0x00000]
+  at Foo.Main () [0x00000]
+Expected Results:
+DSAManaged.ImportParameters should only reject the parameters if both X and
+Y are null. With MS.NET, the runtime will actually automatically calculate
+Y if it is missing in the import.
+How often does this happen?
+Always reproducible.
