RE: [ebxmlms-develop] Digital signaturesIt is, the digest is based on =
the transformed envelope plus all the payloads, that's why you must do =
addDocument before computing the signature.

  I know, but the DigestValue for the SOAP envelope isn't affected by =
the presence of payloads (is it?). If I can't get my SOAP envelope's =
DigestValue to match the one that Hermes produces for the same envelope, =
then there's not much point worrying about the final signature value =
yet.

  Hi Peter,=20
  you'll need to add the payloads as well, they get computed into the =
digest. Either send yourself a signed message w/o payloads, or add the =
payloads in the test routine with addDocument.

  I've written (borrowing heavily from one of the samples) the attached =
rather crude program that takes an ebXML envelope and signs it. For =
input, I'm trapping a signed message from Hermes, editing out the =
headers, mime boundaries, attachments, etc, removing the signature, and =
using the remaining envelope.

  I've compared it to ApacheXMLDSigner.sign() and they look similar as =
far as I can tell.=20
  Unfortunately, the DigestValue I get is not the same as the one that =
Hermes generates. (I'm not worried about attachments or signature values =
yet.) Would someone care to have a quick look and spot the differences?

  I'm not sure where XSLT comes in to it.=20
  Thanks.=20
