Hi all,

Crossposting this from Acrobat forum per another user's suggestion...

Does anyone know how the checksum is generated at the form root for XFA forms? It's allegedly in the XFA spec but I can't find what goes into the sha-1 hash So if anyone can point me in the right direction that would be much appreciated...

Thanks!
