2.4.1.2 Cryptographic Provider Type

The type of the CSP used to generate the key pair on the HCEA. There are many different standard data formats and protocols that CSP can use. These are generally organized into types, each of which has its own set of data formats and processing rules. For more information about CSP types, see [MSDN-CSP].

Value: "CSPType" or one of the value names specified in the table in [MS-GPREG] section 3.2.5.1 specifying how the value is deleted.

Type: REG_DWORD.

Size: Equal to size of the Data field.

Data: A 32-bit value consisting of the following type values.

Name	Value	Meaning
PROV_RSA_FULL	0x00000001	Supports both digital signatures and data encryption. It is considered a general purpose CSP. The RSA public key algorithm is used for all public key operations.
PROV_DSS	0x00000003	Supports hashes and digital signatures. The signature algorithm specified by the PROV_DSS provider type is the Digital Signature Algorithm (DSA).
PROV_RSA_AES	0x00000018	Supports the same as PROV_RSA_FULL with additional AES encryption capability.
PROV_DSS_DH	0x0000000D	A superset of the PROV_DSS provider type with Diffie-Hellman key exchange.
PROV_DH_SCHANNEL	0x00000012	Supports both Diffie-Hellman and Schannel protocols.
PROV_RSA_SCHANNEL	0x0000000C	Supports both RSA and Schannel protocols.
PROV_MS_EXCHANGE	0x00000005	Designed for the cryptographic needs of the Exchange mail application and other applications compatible with Microsoft Mail.
