Signature is the block inside result

the thing is $keyInfo->length() is zero, even when I have added the node to $outXML

Hi dear @pareshchouhan.

What's the output of echo $outXML;?

[pareshchouhan]

the second block is the value of echo $outXML , iirc

Hi dear @pareshchouhan, is this ticket still valid?
