Thanks for you answers Mark and you,

I am not talking about the Provider which does support 3DES as written in
the API doc.
As i understand, each provider must be used with a provider type. This
provider type supports a set of algorithms within the overall set of
algorithms supported by the Provider.
That means "Enhanced Provider" can support some algorithms which are not
part of some provider types.
In the API doc it is written that "Enhanced Prov" support 3DES but the
PROV_RSA_FULL type does not include this algorithm...So i would need to use
another provider type (that includes 3DES) along the "Enhanced provider" in
order to use 3DES.

I don't know if I am right and I would appreciate if someone could clarify
it...

Thanks very much

Eric
