X509Certificate2 Constructor (String, SecureString)
Initializes a new instance of the X509Certificate2 class using a certificate file name and a password.
Namespace: System.Security.Cryptography.X509Certificates
Assembly: System (in System.dll)
Parameters
- fileName
- Type: System.String
The name of a certificate file.
- password
- Type: System.Security.SecureString
The password required to access the X.509 certificate data.
| Exception | Condition |
|---|---|
| CryptographicException | An error with the certificate occurs. For example:
|
This constructor is used with PKCS12 (PFX) files that contain the certificate's private key. Calling this constructor with the correct password decrypts the private key and saves it to a key container.
 Security 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 up the assembly in a text editor such as Notepad.exe. |
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.
