Message-ID: <courier.41933145.00002BE7@outertech.com>

Hi!

I get following error if I try to decode a smime file. but there is no
exception if I use no smime file. it just encodes it.

.....
   p7, data = SMIME.smime_load_pkcs7("../daten/daten.smime")
 File "/usr/lib/python2.3/site-packages/M2Crypto/SMIME.py", line 82, in
smime_load_pkcs7
   p7_ptr, bio_ptr = m2.smime_read_pkcs7(bio)
SystemError: error return without exception set

you can find the file at http://robert.private.outertech.com/daten.smime

Hi!

I've following problem with m2crypto-0.13.

p7, data =
SMIME.smime_load_pkcs7_bio(BIO.MemoryBuffer(open("../daten/testmail.eml",
"rb").read()))

returns

File "/usr/lib/python2.3/site-packages/M2Crypto/SMIME.py", line 93, in
smime_load_pkcs7_bio
 p7_ptr, bio_ptr = m2.smime_read_pkcs7(p7_bio._ptr())
SystemError: error return without exception set

but

p7, data = SMIME.smime_load_pkcs7("../daten/testmail.eml")

works.

Hi,

I've, uh, been unbusy. In fact, I've been enjoying a long holiday weekend.
;-)

> SystemError: error return without exception set

This isn't right. Do I understand correctly that, according to the your
input testmail.eml, this shouldn't throw an error?

Or is it the case that the first chunk of code - smime_load_pkcs7_bio() -
is wrong and the second chunk - smime_load_pkcs7() - is the correct way to
do ... whatever it is that you're doing? (I've been away from the S/MIME
code for quite a while and can't tell off-hand the purpose of the code,
sorry.)

Cheers.

the testmail.eml works if I use the smime_load_pkcs7() function. it loads it
directly from the given file. But I don't want to save my smime content to a
file and check it than. so I looked at a way to use a stream. I found the
smime_load_pkcs7_bio() function. This means I normally get a stream, and
don't need to use open("../daten/testmail.eml","rb".read())) and than call
the smime_load_pkcs7_bio(BIO.MemoryBuffer(..)) stuff.

I just used that to show you that there is an error in your code, as its the
same input file, which works in smime_load_pkcs7().

ps: both code examples are used in following howto
http://sandbox.rulemaker.net/ngps/m2/howto.smime.html. so I assume it worked
at some point.

no the first code is ok. I've it from the above example.

I hat a look at both functions. the smime_load_pkcs7() uses an c function to
create an BIO object and the smime_load_pkcs7_bio uses the given one. but
than the code is the same.

so I believe there is an error in the code.

Ah, now I understand. Yes, the code in the howto worked when I wrote it.

So something has changed that breaks this... What OS, Python, and OpenSSL
versions are you using?

Thanks. Cheers.

Perhaps I'm completely out of the problem, but I suspect it could be a
problem in the format of the file... could it be that it is in der
rather than in pem format?

IIRC, we had a similiar problem, and we create an ad hoc method to
resolve the problem...

Marco

but how explains that that it works in the non_bio version but not in the
bio version of the function?

My only suggestions is that in the non_bio version it does:

m2.bio_new_file(p7file, 'r')

while you do

open('filename', 'rb')

I don't know if it makes any difference, however...

Marco

1. I did also try only r
2. its all base64 encoded so it makes no difference

Am I correct that this file 'testmail.eml' is not the same as this one?

    http://robert.private.outertech.com/daten.smime

If yes, please send me testmail.eml. Thanks.

no its not the same one.
