C# Class PInvoke.Crypt32

Public Methods

Method	Description
CryptAcquireCertificatePrivateKey ( IntPtr pCert, CryptAcquireCertificatePrivateKeyFlags dwFlags, IntPtr pvParameters, SafeHandle &cryptHandle ) : bool	Obtains the private key for a certificate. This function is used to obtain access to a user's private key when the user's certificate is available, but the handle of the user's key container is not available. This function can only be used by the owner of a private key and not by any other user. If a CSP handle and the key container containing a user's private key are available, the CryptGetUserKey function should be used instead.

public static CryptAcquireCertificatePrivateKey ( IntPtr pCert, CryptAcquireCertificatePrivateKeyFlags dwFlags, IntPtr pvParameters, SafeHandle &cryptHandle ) : bool
pCert	System.IntPtr	The address of a CERT_CONTEXT structure that contains the certificate context for which a private key will be obtained.
dwFlags	CryptAcquireCertificatePrivateKeyFlags	A set of flags that modify the behavior of this function. This can be zero or a combination of one or more of values.
pvParameters	System.IntPtr	/// If the is set, then this is the address of an HWND. If the is not set, then this parameter must be NULL. /// Windows Server 2008 R2, Windows 7, Windows Server 2008, Windows Vista, Windows Server 2003 and Windows XP: This parameter was named pvReserved and reserved for future use and must be NULL. ///
cryptHandle	System.Runtime.InteropServices.SafeHandle	/// Receives a safe handle to either CNG key handle of type NCRYPT_KEY_HANDLE or CryptoAPI provider handle of type HCRYPTPROV. ///
return	bool
