X509Certificate2.Import Method (Byte[], SecureString, X509KeyStorageFlags)

Populates an X509Certificate2 object using data from a byte array, a password, and a key storage flag.

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

[PermissionSetAttribute(SecurityAction.InheritanceDemand, Unrestricted = true)]
[PermissionSetAttribute(SecurityAction.LinkDemand, Unrestricted = true)]
public override void Import(
	byte[] rawData,
	SecureString password,
	X509KeyStorageFlags keyStorageFlags
)

Parameters

rawData
Type: System.Byte[]
A byte array that contains data from an X.509 certificate.
password
Type: System.Security.SecureString
The password required to access the X.509 certificate data.
keyStorageFlags
Type: System.Security.Cryptography.X509Certificates.X509KeyStorageFlags
A bitwise combination of the enumeration values that control where and how to import the private key of the certificate.

You can use this method for certificate types such as Base64-encoded or DER-encoded X.509 certificates, or PFX/PKCS12 certificates. Note that a PFX/PKCS12 certificate can contain more than one certificate. In that case, the first certificate associated with a private key is used or, if no private key is found, the first certificate is used.

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 up the assembly in a text editor such as Notepad.exe.
