How can I convert an uploaded file to an X509Certificate2 variable?
I have tried using the following code but it is not working:
public bool hasPublicKey(FileUpload file)
{
bool check = false;
try
{
X509Certificate2 cert = (X509Certificate2)file.PostedFile.InputStream;
}
catch(Exception)
{
check = false;
}
}
If the uploaded file is a valid certificate you should have a look at the constructor or Import method in the X509Certificate2 class.
You'll see that you need to something like this:
var fileLength = file.PostedFile.ContentLength;
var certdata = new byte[fileLength];
file.FileContent.Read(certData, 0, fileLength);
var cert = new X509Certificate2(certData);
(code not verified but it, or something very similar, should work).
