X509Certificate Constructor (array<Byte[], String)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

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)

Syntax

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

public X509Certificate(
    byte[] rawData,
    string password
)

Parameters

  • rawData
    Type: array<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.

Exceptions

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

-or-

The length of the rawData parameter is 0.

Remarks

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 by using the MSIL Disassembler (Ildasm.exe), by using a hexadecimal 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 instead of the certificates within the store.
