X509Certificate Constructor (array<Byte>[]()[], String, X509KeyStorageFlags)
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
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)
Syntax
Public Sub New ( _
rawData As Byte(), _
password As String, _
keyStorageFlags As X509KeyStorageFlags _
)
public X509Certificate(
byte[] rawData,
string password,
X509KeyStorageFlags keyStorageFlags
)
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.
- keyStorageFlags
Type: System.Security.Cryptography.X509Certificates..::.X509KeyStorageFlags
One of the enumeration values.
Exceptions
Exception | Condition |
---|---|
CryptographicException | An error with the certificate occurs. For example:
|
ArgumentException | The rawData parameter is nullNothingnullptra null reference (Nothing in Visual Basic). -or- The length of the rawData parameter is 0. |
Remarks
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 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.
rawDatadoes not accept input data formatted in the PKCS #12 format.
Version Notes
Windows Phone
If you pass an invalid X509KeyStorageFlags value when you create an X509Certificate, a NotSupportedException occurs instead of ArgumentException.
