Question

Im creating xml string from my RSA key:

var keyXmlString = rsaPrivKey.ToXmlString(true);

And now i would like to convert the string to bytes, something like this:

var xmlBytes = Encoding.Unicode.GetBytes(keyXmlString);

The question is wehat would be the right encoding to use there wehn converting xml string to bytes?

Answer 1

There is no “right” encoding here – it depends, on who is your consumer. You need to use the encoding, your consumer expects.

I strongly suggest to do something like

var xmlBytes = Encoding.YOURENCODINGHERE.GetBytes("<?xml version=\"1.0\" encoding=\"YOURENCODINGHERE\" ?>\n"+keyXmlString);

to make this more foolproof.
