Public Sub New (fileName As String, password As String, keyStorageFlags As X509KeyStorageFlags)
Parameters
- fileName
- String
The name of a certificate file.
- password
- String
The password required to access the X.509 certificate data.
- keyStorageFlags
- X509KeyStorageFlags
A bitwise combination of the enumeration values that control where and how to import the certificate.
- Attributes
Exceptions
An error with the certificate occurs. For example:
The certificate file does not exist.
The certificate is invalid.
The certificate's password is incorrect.
Remarks
This constructor creates a new X509Certificate2 object using a certificate file name, a password needed to access the certificate, and a key storage flag.
Important
Never hard code a password within your source code. Hard-coded passwords can be retrieved from an assembly using the Ildasm.exe (IL Disassembler), a hex editor, or by simply opening up the assembly in a text editor such as Notepad.exe.
If you create an X509Certificate2 certificate by specifying a PKCS7 signed file store for fileName
, the X509Certificate2 is created for the certificate that signed the store rather than for any of the certificates within the store.

Public Sub New (rawData As Byte(), password As String, keyStorageFlags As X509KeyStorageFlags)
Parameters
- rawData
- Byte[]
A byte array containing data from an X.509 certificate.
- password
- String
The password required to access the X.509 certificate data.
- keyStorageFlags
- X509KeyStorageFlags
A bitwise combination of the enumeration values that control where and how to import the certificate.
- Attributes
Exceptions
An error with the certificate occurs. For example:
The certificate file does not exist.
The certificate is invalid.
The certificate's password is incorrect.
Remarks
This constructor creates a new X509Certificate2 object using a byte array, a password that is needed to access the certificate data, and a key storage flag. It 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 Microsoft Cryptographic API Cryptographic Service Provider (CSP).
Important
Never hard code a password within your source code. Hard-coded passwords can be retrieved from an assembly using the Ildasm.exe (IL Disassembler), a hex editor, or by simply opening up the assembly in a text editor such as Notepad.exe.
If you create an X509Certificate2 certificate by specifying a PKCS7 signed file store for rawData
, the X509Certificate2 is created for the certificate that signed the store rather than for any of the certificates within the store.

Public Sub New (rawData As Byte(), password As SecureString, keyStorageFlags As X509KeyStorageFlags)
Parameters
- rawData
- Byte[]
A byte array that contains data from an X.509 certificate.
- password
- SecureString
The password required to access the X.509 certificate data.
- keyStorageFlags
- X509KeyStorageFlags
A bitwise combination of the enumeration values that control where and how to import the certificate.
- Attributes
Exceptions
An error with the certificate occurs. For example:
The certificate file does not exist.
The certificate is invalid.
The certificate's password is incorrect.
Remarks
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 Microsoft Cryptographic API Cryptographic Service Provider (CSP).
Important
Never hard code a password within your source code. Hard-coded passwords can be retrieved from an assembly using the Ildasm.exe (IL 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 rawData
, the X509Certificate is created for the certificate that signed the store rather than for any of the certificates within the store.

Remarks
This constructor creates a new X509Certificate2 object using a handle for the Microsoft Cryptographic API certificate context, PCCERT_CONTEXT
. Note that the immediate caller of this constructor requires unmanaged code permission.
Important
The constructor creates a copy of the certificate context. Do not assume that the context structure you passed to the constructor is valid; it may have been released. You can get a copy of the current PCCERT_CONTEXT
structure from the Handle property, but it is valid only during the lifetime of the X509Certificate2 object.

Public Sub New (rawData As Byte())
Parameters
- rawData
- Byte[]
A byte array containing data from an X.509 certificate.
- Attributes
Exceptions
An error with the certificate occurs. For example:
The certificate file does not exist.
The certificate is invalid.
The certificate's password is incorrect.
Remarks
This constructor creates a new X509Certificate2 object using certificate information from a byte array. The byte array can be binary (DER) encoded or Base64-encoded X.509 data. The byte array can also be a PKCS7 (Authenticode) signed file; the signer certificate is used to create the object.
If you create an X509Certificate2 certificate by specifying a PKCS7 signed file store for rawData
, the X509Certificate2 is created for the certificate that signed the store rather than for any of the certificates within the store.
