X509Certificate Constructor (String^, String^)

 

Initializes a new instance of the X509Certificate class using the name of a PKCS7 signed file and a password to access the certificate.

Namespace:   System.Security.Cryptography.X509Certificates
Assembly:  mscorlib (in mscorlib.dll)

public:
X509Certificate(
	String^ fileName,
	String^ password
)

Parameters

fileName
Type: System::String^

The name of a PKCS7 signed file.

password
Type: System::String^

The password required to access the X.509 certificate data.

Exception Condition
CryptographicException

An error with the certificate occurs. For example:

  • The certificate file does not exist.

  • The certificate is invalid.

  • The certificate's password is incorrect.

ArgumentException

The fileName parameter is null.

ASN.1 DER is the only certificate format supported by this class. Calling this constructor with the correct password decrypts the private key and saves it to a key container.

If you create an X509Certificate certificate by specifying a PKCS7 signed file store for fileName, the X509Certificate is created for the certificate that signed the store rather than for any of the certificates within the store.

FileIOPermission

KeyContainerPermission

for permission to create a key container. Security action: Demand. Associated enumeration: KeyContainerPermissionFlags::Create
