Hi,
I'm currently trying to create an AsymmetricKeyParameter public key
parameter from an xml string like this:
public static AsymmetricKeyParameter xmlStringToPubKey(string
xmlString)
{
//AsymmetricCipherKeyPair keyPair;
if (String.IsNullOrEmpty(xmlString))
{
Console.WriteLine("Empty XML string received");
return null;
}
else
{
XDocument xdoc = XDocument.Parse(xmlString);
return
PublicKeyFactory.CreateKey(Streamify(xdoc.Descendants("Modulus").First().Value));
}
}
However, I'm getting an exception when calling CreateKey on
PublicKeyFactory obj. xdoc.Descendants returns a string which needs
to
be converted into an array of bytes. I've tried different ways to
convert the string:
- Encoding.Unicode.getBytes(xmlString)
- getBytes(xmlString) method I've created to return a byte array from
a string
- Streamify - another method I've created to return a Stream
While I get different exceptions on each of the above methods none
seem to work. Any hints appreciated.
