X509Certificate Constructor (Byte(), String)

Initializes a new instance of the X509Certificate class using a byte array and a password.

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

'Declaration
Public Sub New ( _
	rawData As Byte(), _
	password As String _
)

Parameters

rawData
Type: System.Byte()
A byte array containing data from an X.509 certificate.
password
Type: System.String
The password required to access the X.509 certificate data.

ExceptionCondition
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 Nothing.

-or-

The length of the rawData parameter is 0.

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 Ildasm.exe (MSIL Disassembler), 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.
