Hi, I am attempting to utilise the OpenSSL RSA functionality to verify UN standard Edifact files with AUTACK messages containing a signature which has been generated using the SHA-1 digest. Also I need to produce a corresponding outgoing AUTACK with an embedded signature attached to the Ack or Nak message.
I have been able to sign and verify locally using the SSL software but my problem is the intermediate signature does not match that expected by the 3rd parties we deal with. Indeed they do not match examples given by the Edifact documentation in the worked examples. I get the expected digest values but the RSA generated signature is completely different. The Edifact documentation says the RSA verification should comply with ISO9796-1. I can find no mention of ISO standards at all in the release so maybe you can confirm whether or not this might be the problem.
