[stunnel-users] SSL Engine patch on Windows?

[Kartik Subbarao]

I'm trying to use stunnel with the SSL Hardware Engine patch (posted by 
Neil Dunbar to this mailing list in March) on Windows.

I apply the patch to the 4.05 codebase and build stunnel with MinGW. I'm 
able to use stunnel normally without exercising any hardware engine 
functionality. This tells me that the basics are working.

I then run stunnel with the config file containing the following kinds 
of hardware engine parameters:

SSLEngine=c:\windows\system32\engine_pkcs11.dll
SSLEngineOpt=MODULE_PATH=c:\windows\system32\acpkcs201.dll

But when I run stunnel, I get errors with dynamic library loading like:

error stack: 260B6084 : error:260B6084:engine routines:DYNAMIC_LOAD:dso 
not found

And similar errors like that. This gives me the impression that I 
haven't linked stunnel properly on windows to be able to use OpenSSL 
dynamic libraries. Or perhaps some other explanation that I don't 
understand :-)

Is it possible to compile stunnel on Windows (either with MinGW or with 
Visual C++) to be able to use the hardware engine patch? Any 
pointers/assistance would be greatly appreciated.

Thanks,
