Hi all,

I'm trying to verify a PDF that was signed with S-Trust Sign-IT. Thats a
software sold by a german bank and used for qualified digital signatures.
>From a technical point of view its just an SMIME Signature.

I'm running this command:

[EMAIL PROTECTED]:~/test/openssl/strust$ openssl smime -binary -verify -in
rechnung.pdf.p7s -inform der -out /dev/null -content rechnung.pdf
-CAfile strustx.pem

Where rechnung.pdf.p7s contains the signature, and strustx.pem the root
and subcertificates. I'm getting this error, also the Sign-IT Software
confirms the signature as valid:

Verification failure
19424:error:04077064:rsa routines:RSA_verify:algorithm
mismatch:rsa_sign.c:228:
19424:error:21071069:PKCS7 routines:PKCS7_signatureVerify:signature
failure:pk7_doit.c:961:
19424:error:21075069:PKCS7 routines:PKCS7_verify:signature
failure:pk7_smime.c:299:


I searched the web for quite a long time, but I can't find anything
explaining the errormessage to me. Did I miss an argument that has to be
passed to openssl or is it more likly that Sign-IT isn't compatible to
OpenSSL?


Thanks for any help!

Regards
Ben
