<p class="MsoNormal">We have the need to sign a snippet of XML with an X509 digital certificate. The algorithm is to canonicalise the XML, compute a SHA256 hash on this, and sign the hash with the certificate’s private key.<o:p></o:p></p>

<p class="MsoNormal">I can’t see any easy way of doing this within the VCL.<o:p></o:p></p>
