[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"

provider)
Type 018 "Diffie-Hellman SChannel" (optional?)

I am trying to implement AES Provider for rsaenh
After that I may start on dssbase and dssenh
Well, I have to start on them.
But if there are small windows apps that would be great rather than .net apps

Is this still an issue in current (1.0-rc5 or newer) wine?

our current dssenh is merely a stubbed dll, no real implementation of the DSS
Provider has been done.
So Its still an issue.

Hello,

corrected version tag and changed severity because this blocks certain .NET
apps from functioning properly.

One of the apps affected is MadCap Flare (help authoring tool). Trying to
register the program results in a CryptographicException being thrown.

This also happens when installing Toad for MySQL Community. I suspect the app
would run great if this one thing were fixed.  It bombs on install when
creating the "Plugin cache" at the tail end of the install.  Also if you run
the application toad.exe on startup.

Hello folks,

revisiting, still present. We've reached 10 years here _oO_  ... maybe GSoC?

Found another .NET app/game to reproduce with:

http://download.fileplanet.com/ftp1/012011/MinerWars_01_074_006_Setup.exe

Prerequisite:

'wintricks -q dotnet40 xna40'

Fails during auto-update after starting the game from launcher.

Per Paul Gofman this is the cause of Might and Magic Clash of Heroes not
working: https://bugs.winehq.org/show_bug.cgi?id=30244#c24

...which is not a .net app apparently. He attached a hack/patch that renders
that game playable. Don't know why he didn't mention this himself and I meant
to but kind of forgot once I finished the game. :)

[Bug 10506] .NET applications which use 'System.Security.Cryptography.DSA' need crypt32 DSS provider

[WineHQ Bugzilla]

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

--- Comment #21 from Hans Leidekker  ---
We do have a DSS provider now. The issue is that there's no default key
container which makes CryptAcquireContext fail. I'm not sure where or when it
should be created (I recall we had a similar issue with RSA) but running the
dssenh tests also creates it and allows the launcher to proceed.

Bug 30244 has been closed FIXED, someone may want to check if that applies here
or if there's more work needed.

Hello folks,

revisiting, still present. Refining the summary to make it less "meta",
targeting the problem Hans mentioned in comment #21
