[b]Creating an XML signature [/b]

Hi,
I have a mainframe file that I have wrapped with XML.
But we also need to provide that file with an XML signature!

Attached is the structure that is used by the XML signature.
There is a digest value in that structure which, I guess, is the data that needs to be encrypted in the signature.
If that is the case, I have a file that I need to send daily to the bank after wrapping it using XML. How will I insert this data in the XML signature?

Guys, you can provide even the slightest of information you have on XML signature which I hope may help as I need to understand how this works!
I have gone through XML links which are, may be, explanatory; but, since I do not have much idea about XML or HTML I need a response in terms of Cobol prospective or any Cobol related XML project!

Hi,
For all those who may not be able to see my attachment can access the below link which contains the structure of XML signature in the module 2.0 -

the digest is really the result, not the starting data
in rough terms ... is the signature

the answer is a bit complex to be given in a forum reply
( almost as giving full training on signatures )

read about hashing, checksums,signatures, .... ( MD5, SHA1, ...)

the issue is too complex to be managed by a single person ( moreover with limited knowledge )
since it requires some higher responibilities

when dealing with certificates and signatures there is a lot of legal work to be done

better speak with Your security support, or to the manager responsible of the whole thing
