Hi,

I know I have a pretty common problem but I can't find the way to solve it,
even after reading all the messages of this forum.

I need to get my PDF documents signed by external components. It seems like
what I need to do is generate a hash, send it to my external document,
retrieve from it a valid PKCS#7 and insert it into my document.

The problem I have is that everytime a generate a HASH (getting bytes with
getRangeStream) I get a different one, so I can't reproduce the signature
process and insert the PKCS#7 into my file. Does anybody know how to make it
work? How can I generate always the same HASH for one document? I read many
questions about this but no success story.

Thanks in advance,
Jorge Ortiz
