[Bug 10506] New: wine crypt32 needs DSS provider to support more . NET apps which use cryptography API

http://bugs.winehq.org/show_bug.cgi?id=10506

Summary: wine crypt32 needs DSS provider to support more .NET
                    apps which use cryptography API
           Product: Wine
           Version: CVS/GIT
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: wine-crypt32
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Hello,

while playing around with .NET apps I found various shortcomings when it comes
to native backends for certains parts of .NET
One is the state of cryptographic providers (crypt32).

Many .NET apps use either default RSA or DSS provider.
Currently the DSS and enhanced DSS provider are missing, resulting in failure
of several .NET apps.

Would be nice if wine gets DSS provider too.

Trace log showing failure of typical .NET app trying to query DSS provider:

Type 001 "RSA Full (Signature and Key Exchange)" and Type 012 "RSA SChannel"
are currently implemented in wine
Additionally needed:

Type 003 "DSS Signature" (base DSS provider)
Type 013 "DSS Signature with Diffie-Hellman Key Exchange" (enhanced DSS
provider)
Type 018 "Diffie-Hellman SChannel" (optional?)
