PGP Encrypted mail with Gpg4win and Kopano from Outlook


  • Kopano

    Hi @aheinecke ,

    I just remembered this thread, did your customer get in contact with our support?



  • Hello all / @aheinecke,

    recent changes seem to have solved above problems for encryption - gpg-signatures still are broken:

    Gpg4win + Outlook + Kopano OL + Z-Push + Kopano-core + Kopano-webapp produces valid output for GpgOL generated mails.

    Tested 2018-06-19 15:17 CEST with :

    core kc-git-master 8.6.80.1128
    webapp git-master 3.4.15final.221-ga3347f1
    z-push 2.4.3.beta1+6
    GpgOL 2.06
    KOE 3.0.305
    Outlook 16.0.4639

    WebApp received representation of a mail composed in Outlook with GpgOL as below:

  • Malheureusement, the above said is valid for gpg-encryption, only.
    If the mail ist gpg-signed, too or only, the mail arrives with an attachment unknown_content_type.bin containing either the pgp-signature, or the string Version: 1. Additionally, the decrypted body contains MIME-tags.

    Yes, that is what I also was able to observe.



  • …and now the good better news:

    gpg-encryption & signature works as expected for PGP/Inline-messages with GpgOL v2.2.0, which is part of recent Gpg4win 3.1.2 .

    It still fails with wrongly constructed/ parsed MIME-multipart elements (unknown_content_type.bin), unencrypted attachments etc. as soon as Content-Type: multipart/mixed MIME-structures are involved.

    ++umgfoin.

  • Hi,

    how is the actual state of this point? Is it solved?

    I’m wondering if this problem maybe could be a problem of gpb4win and not kopano: there is a alternative gpg plugin existing for outlook 2016 (and other versions) called gpg4o that works perfectly with outlook and kopano.

    If you need further data, please let me know…

    Kind regards

    Rolf


  • Kopano

    @rolf as you can see in the reply from @umgfoin it seems to work now (that is what I also experienced when I tried it the last time)



  • @fbartels thats unfortunately just 50%.

    • It still doesnt work when sending crypted (and optionally signed) messages with attachments.
    • with attachments it just works when receive
    • the way to use pgp/inline is just a workaround and NOT a solution.

    sorry, but the bug is still existing and prevents the usage of a lot of pgp usecases.

    is there the possibility that this may be solved this year? That’ll be great :-)

    Kind regards

    Rolf

    Ah, I wasn’t aware since I just briefly tried it out myself.

    PGP currently isn’t a priority for us at Kopano. If an external developer want to dive into this then patches are welcome.
