Need dll for digital sign [login to view URL] dll must put <ds:Signature> tag in [login to view URL] signing algorithm can be RSA or DSA and ds prefix is mandatory.
Here are example
<ds:Signature xmlns:ds="[login to view URL]">
<ds:SignedInfo>
<ds:CanonicalizationMethod Algorithm="[login to view URL]" />
<ds:SignatureMethod Algorithm="[login to view URL]" />
<ds:Reference URI="">
<ds:Transforms>
<ds:Transform Algorithm="[login to view URL]" />
<ds:Transform Algorithm="[login to view URL]" />
</ds:Transforms>
<ds:DigestMethod Algorithm="[login to view URL]" />
<ds:DigestValue>khBYs..=</ds:DigestValue>
</ds:Reference>
</ds:SignedInfo>
<ds:SignatureValue>XBv9..==</ds:SignatureValue>
<ds:KeyInfo>
<ds:X509Data>
<ds:X509Certificate>c8K9s..=</ds:X509Certificate>
</ds:X509Data>
<ds:KeyValue>
<ds:DSAKeyValue>
<ds:P>/X9Tg.. =</ds:P>
<ds:Q>l2BQ..=</ds:Q>
<ds:G>9+Gg..=</ds:G>
<ds:Y>urTf..=</ds:Y>
</ds:DSAKeyValue>
</ds:KeyValue>
</ds:KeyInfo>
</ds:Signature>
If you can't do this please don't [login to view URL] take project and say that everything is ready and after that aborted project and i can't give them bad [login to view URL] return my 30 usd that take for project.
