process of generating the <SignedInfo> tag: 1. inherit namespaces to signed info, like this: <SignedInfo xmlns="http://www.w3.org/2000/09/xmldsig#"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";> 2. apply xml-c14n-20010315 to SignedInfo 3. apply rsa-sha1 4. apply base64 4. now you have <SignatureValue>
the namespaces inherited in 1. are correct ? because from DOM if you obtain the namespace at the node SignedInfo it only says xmlns, but it misses the xmlns:xsi, which is included in the signature value. - <Signature xmlns="http://www.w3.org/2000/09/xmldsig#"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";> - <SignedInfo> <CanonicalizationMethod Algorithm="http://www.w3.org/TR/2001/REC-xml-c14n-20010315"; /> <SignatureMethod Algorithm="http://www.w3.org/2000/09/xmldsig#rsa-sha1"; /> - <Reference URI="#SetDoc"> <DigestMethod Algorithm="http://www.w3.org/2000/09/xmldsig#sha1"; /> <DigestValue>pYaS4AXr+cw9w0u3kf46HhEoVBQ=</DigestValue> </Reference> </SignedInfo> <SignatureValue>tCdka7RC0a5KccFS3fOUkIvBnP1cH6+VedU0/mianuFgqaLxRrnnnExlbjNQ 9CcjHTXQ7kows3W+ SXE0DzBkXV5rjWXXlfgGD1Tqoo7+tAyP+6XKplwzlPABFVDW2cLyr9ikQNFduTx+pKPZOgff4kzt rxLzWtryW7jB6MSOdRY=</SignatureValue> - <KeyInfo> ......
