X509Certificate.X509Certificate(Byte[], String, X509KeyStorageFlags) Constructor

Initializes a new instance of the X509Certificate class using a byte array, a password, and a key storage flag.

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

public X509Certificate (
	byte[] rawData,
	string password,
	X509KeyStorageFlags keyStorageFlags
)
public X509Certificate (
	byte[] rawData, 
	String password, 
	X509KeyStorageFlags keyStorageFlags
)
public function X509Certificate (
	rawData : byte[], 
	password : String, 
	keyStorageFlags : X509KeyStorageFlags
)
Not applicable.

Parameters

rawData

A byte array containing data from an X.509 certificate.

password

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

keyStorageFlags

One of the X509KeyStorageFlags values.

Exception typeCondition

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 rawData parameter is a null reference (Nothing in Visual Basic).

-or-

The length of the rawData parameter is 0.

This constructor creates a new X509Certificate object using a byte array, a password that is needed to access the certificate data, and a key storage flag. Calling this constructor with the correct password decrypts the private key and saves it to a Microsoft Cryptographic API Cryptographic Service Provider (CSP).

The X509KeyStorageFlags value can be used to control where and how the private key is imported.

ASN.1 DER is the only certificate format supported by this class.

Security noteSecurity Note:

Never hard code a password within your source code. Hard-coded passwords can be retrieved from an assembly using the MSIL Disassembler (Ildasm.exe), a hex editor, or by simply opening the assembly in a text editor such as Notepad.exe.

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