[Mono-list] Assembly Signing with PFX files

[met at uberstats.com]

I've looked around, but I can't seem to find anything. Is it possible  
to sign .NET assemblies produced with gmcs with PFX files? I ask  
because I have a .NET project building under VS2005 which is using  
PFX. I would like to built it under Mono and sign it, but currently I  
don't know how as its not a SNK.

What piece am I missing to this seemingly simple puzzle.

Thanks,
