title: How to sign XML document or verify XML document signature with C++?
body: <p>Subj. I need to sign/verify under Windows in native C++ (no .NET), using private key for signing, public key for verification.</p>
  
  <p>I saw few examples on MSDN (<a href="http://msdn.microsoft.com/en-us/library/ms761363(VS.85).aspx" rel="nofollow noreferrer">http://msdn.microsoft.com/en-us/library/ms761363(VS.85).aspx</a>) that demonstrate how to sign the document with CSP (I don't know what this means).</p>
  
  <p>For my case I need to use a "key" from the binary data array (using DSA encryption algorithm)... can somebody help me with that?</p>
  
  <p>Thank you in advance.</p>
