RawData |
Gets the raw data of the certificate. |
The RawData property returns the contents of the certificate in its original binary format. This is useful for scenarios where you need to access the raw bytes of the certificate, such as for signing, encryption, or for transmitting the certificate to another system.
The data returned by this property is the DER-encoded (Distinguished Encoding Rules) representation of the X.509 certificate.
Accessing this property requires the UnmanagedCode permission, as indicated by the SecurityPermissionAttribute.

The following code example demonstrates how to retrieve the raw data of an X.509 certificate.
using System;
using System.Security.Cryptography.X509Certificates;
using System.Security.Permissions;
public class Example
{
public static void Main()
{
// Assuming 'cert' is an initialized X509Certificate2 object
X509Certificate2 cert = new X509Certificate2("path/to/your/certificate.cer"); // Replace with your certificate path
try
{
// Request the UnmanagedCode permission to access RawData
new SecurityPermission(SecurityPermissionFlag.UnmanagedCode).Demand();
byte[] rawData = cert.RawData;
Console.WriteLine("Raw data retrieved successfully. Length: {0} bytes", rawData.Length);
// You can now use the rawData byte array for further operations
// For example, save it to a file:
// System.IO.File.WriteAllBytes("certificate.cer.raw", rawData);
}
catch (SecurityException secEx)
{
Console.WriteLine("Security exception: {0}", secEx.Message);
}
catch (Exception ex)
{
Console.WriteLine("An error occurred: {0}", ex.Message);
}
}
}
