Bug ID: 39681
           Summary: Unimplemented function
                    crypt32.dll.CryptMsgVerifyCountersignatureEncoded
           Product: Wine
           Version: 1.7.53
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: crypt32

MS dotnet's SignedCms.CheckSignature() depends on
crypt32.dll.CryptMsgVerifyCountersignatureEncoded .

I found this out while running a test program which does exactly that:

Unhandled Exception: System.Runtime.InteropServices.SEHException: External
component has thrown an exception.

(Apologies the wine version may not be accurate if this report is version
sensitive - I kept a note on this error on Nov 2, but I upgraded wine to 1.7.55
on No 20; so the actual error would have been observed approximately with
1.7.54/1.7.53/1.7.52)
