DPSECURITYDESC

The DPSECURITYDESC structure describes the security properties of a DirectPlay session instance.

typedef struct {
    DWORD  dwSize;
    DWORD  dwFlags;
    union {           
        LPWSTR  lpszSSPIProvider;   
        LPSTR   lpszSSPIProviderA;  
    };
    union {
        LPWSTR lpszCAPIProvider;    
        LPSTR  lpszCAPIProviderA;   
    };
    DWORD  dwCAPIProviderType;       
    DWORD  dwEncryptionAlgorithm; 
} DPSECURITYDESC, FAR *LPDPSECURITYDESC;

Members

dwSize

The size of the DPSECURITYDESC structure, dwSize = sizeof(DPSECURITYDESC).

dwFlags

Not used. Must be 0.

lpszSSPIProvider, lpszSSPIProviderA

Pointer to a Unicode or ANSI string describing the Security Support Provider Interface (SSPI) package to use for authenticated logons. Pass NULL to use the default, the NTLM (NT LAN Manager) security provider.

lpszCAPIProvider, lpszCAPIProviderA

Pointer to a Unicode or ANSI string describing the CryptoAPI package to use for cryptography services. Pass NULL to use the default, the Microsoft RSA Base Cryptographic Provider v. 1.0.

dwCAPIProviderType

CryptoAPI service provider type. Pass 0 to use the default type, PROV_RSA_FULL.

dwEncryptionAlgorithm

Encryption algorithm to use. DirectPlay only supports stream ciphers. Pass 0 to use the default, the CALG_RC4 stream cipher.

Remarks

DirectPlay does not support block encryption.
