WinCAPICryptoProvider

[Milan Tomic <mi...@setcce.org>]

Berin,

	I can see that "WinCAPICryptoProvider cp" is declared twice in
checksig.cpp and never in threadtest.cpp. Please, could you explain why?
Does we need it and when?

Thank you,
Milan

Milan,

checksig allows the user to select between WinCAPI and OpenSSL when both 
are present.  (BTW - The second usage is really redundant, it's a 
hangover from old code.)

Threadtest cheats :>.  By default, if the library has both OpenSSL and 
WinCAPI available, it will use OpenSSL.  So Threadtest simply does a 
check for OpenSSL - if it's there, it creates an OpenSSL based key.  If 
not, it uses WinCAPI.

SO the rule of thumb - define a crypto provider if more than one is 
compiled into the library and you want to select the one that wouldn't 
be used by default.

Cheers,
	Berin
