Hello,

Thanks for respending.

I have set the cprovidername in the class to "Microsoft Base Cryptographic Provider v1.0" already !

>It was reported elsewhere that the problem is that the default Crypto Provider is different for Windows 2000 and XP. It is Microsoft Base Cryptographic Provider (Rsabase.dll) for Windows 2000 and Microsoft Enhanced Cryptographic Provider (Rsaenh.dll) for Windows XP.
>To fix it, try to set 'cprovidername' property of the _cryptapi class to "Microsoft Base Cryptographic Provider v1.0" which is value of dsMS_DEF_PROV_A constant in the wincrypt.h include file.
