[xmlsec] Verification using mscrypto library

[Tomas Stejskal]

Hello,

I'm trying to verify document with included X509 certificate using 
mscrypto library, but without success.
When I call xmlSecDSigCtxVerify, I get these errors:

func=xmlSecKeysMngrGetKey:file=..\src\keys.c:line=1364:obj=unknown:subj=xmlSecKeysMngrFindKey:error=1:xmlsec 
library function failed: ;last error=-2146885628 (0x80092004);last error 
msg=Objekt nebo vlastnost nebyly nalezeny.

msg=Objekt nebo vlastnost nebyly nalezeny.

I'd be very grateful for any example code or an advice how to achieve it.
