Quoting Philipp Faeustlin <philipp.faeust...@uni-hohenheim.de>:
Hi there,
I have encrypted and signed smime mails out of a Groupwise Client that
are not displayed correctly. The signed message is only displayed as
attachment "smime.p7m" File.
These mails have an encrypted outer section:
---
Content-Type: application/x-pkcs7-mime; name=smime.p7m
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
---
Within the encrypted part, there is a signed part with the message as:
---
Content-Type: application/pkcs7-mime
Content-Transfer-Encoding: base64
Content-Disposition: attachment; filename="smime.p7m";
---
I think the ASN1 decoding of the decrypted "smime.p7m" file probably
doesn't work correct.
Because if the signed part is declared as
"Content-Type: application/x-pkcs7-mime; name=smime.p7m;
smime-type=signed-data", with the smime-type field signed-data, the
message is displayed.
I researched the code and found a one line hack/work-around to display
the messages correctly.
I added to the [webdir]/imp/lib/Mime/Viewer/Smime.php the following on
line 234:
$new_part->setContentTypeParameter('smime-type', 'signed-data');
With this line added my problem is solved, but I'm not sure if this is
the right solution to this problem. Or the other way round, I can't
say what problem this line can cause.
Any ideas of a better solution?\
What version of IMP are you using?
Imp 6.2.21
Horde_Crypt 2.7.11
The last release via pear.
Best regards
