Microsoft RSA Base Provider

Rsabase.dll, the Microsoft RSA Base Provider included with Windows CE, consists of a software implementation of the PROV_RSA_FULL provider type. PROV_RSA_FULL supports both digital signatures and data encryption, and is considered to be a general-purpose cryptographic tool. For more information about PROV_RSA_FULL, see the Microsoft Windows SDK.

The following table shows the algorithms supported by the Microsoft Base Cryptographic Provider.
