I don't need no feature like verify sign, or sign using a certificate.

For PDF files you can just remove the P7M content before %PDF and after
%%EOF.
The following snippet converts /tmp/test.p7m into PDF, saving the
resulting document into /tmp/test.pdf:
import re
from gzip import GzipFile
contents = GzipFile('/tmp/test.p7m').read()
contents_re = re.compile('%PDF-.*%%EOF', re.MULTILINE | re.DOTALL)
contents = contents_re.search(contents).group()
open('/tmp/test.pdf', 'w').write(contents)
After all those days... only to say THANKS!
The example of the PDF file is perfect, I only needed to not execute
the GzipFile call (it seems that our PDF are not GZipped).
Unluckily now seems that we need the same feature for non-pdf files...

HTH.

For PDF files you can just remove the P7M content before %PDF and after %%EOF. If the .p7m is a S/MIME message then it might be encrypted. So you have to decrypt it. It could also be a opaque-signed S/MIME message. But still I'd use a decent S/MIME module to extract the stuff therein. Ciao, Michael. -- http://mail.python.org/mailman/listinfo/python-list

I'm there again!
I found a document and some exaples related to the M2Crypto library
http://eckhart.stderr.org/doc/python-m2crypto-doc/doc/howto.smime.html
I tryed to use this:
from M2Crypto import BIO, SMIME, X509
p7, data = SMIME.smime_load_pkcs7('/Users/luca/Desktop/testsigned.pdf.p7m')
Traceback (most recent call last):
File stdin, line 1, in ?
File build/bdist.macosx-10.5-i386/egg/M2Crypto/SMIME.py, line 91,
in smime_load_pkcs7
M2Crypto.SMIME.SMIME_Error: no content type
May be this is the wrong library... but even Google can't help me a
lot with this problem :-(
I can't help with your particular problem but there are quite a few
people familiar with M2Crypto lurking on the python-crypto mailing list:
https://listserv.surfnet.nl/archives/python-crypto.html
Despite this Dutch entry page the language written on the mailing list
is English.

Read a content file from a P7M
Hi all. There is standard or sugested way in python to read the content of a P7M file? I don't need no feature like verify sign, or sign using a certificate. I only need to extract the content file of the p7m (a doc, a pdf, ...) Thanks! -- -- luca -- http://mail.python.org/mailman/listinfo/python-list
