Help on Table Encryption

[Const]

Hi,
I found on Internet a little class (cryptoApi) which I adapt to encrypt and decrypt a table located in a database. I develop on WIN2000 and it is still working. But on my other computer which is running under WIN XP, it doesn't work. Does anyone know why?

Thanks

In what way does it not work? It doesn't encrypt or it causes an error?

Const,
I found this explanation and fix on the UniversalThread (

http://www.universalthread.com/)

by Sergey Berezniker:

"... 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. "
