    I have successfully used Thunderbird/Enigmail for signed and encrypted mail for a long time. I have, at long last, managed to get a version of Gpg4win (2.1.1.beta 197) working on my Outlook 2007 set-up, and have been testing with mails from one to the other. As they are on the same machine they are using the same keyring and keys. Signed and encrypted mail from Thunderbird to Outlook works just fine. Mail from Thunderbird/Enigmail to Thunderbird/Enigmail works OK. Mail from Outlook 2007 to Outlook 2007 works perfectly too. However, mail from Outlook/gpg4win to Thunderbird/Enigmail is decypted OK, but the signature fails to verify every time. There is no normal Enigmail coloured band at the top of the screen, the signature appears at the bottom as an attached text file. If I open it, it gives a bad signature. The same applies if the messages are only signed and not encrypted.

    Werner Kock tells me that test messages from me using Outlook/gpg4win set-up verify OK,

    your test mail verified fine using after the saving the file to a Unix
    mailbox file:

    ~/b/gnupg/tools/gpgparsemail --crypto test.mbox

    I use this tool to parse and verify MIME messages. The GpgOL MIME
    parser is actually based on code from this tool.

    Any ideas as to what might be wrong, or where I should start looking for the problem?

    Regards,

    Bob

    Can you attach a sample message?

    I've attached a message written from one of my addresses to another using Outlook/Gpg4win to Thunderbird/Enigmail. The message received in Thunderbird shows a yellow band across the top with "Unverified signature; click on 'Details' button for more information". Clicking "Details" only shows "OpenPGP security info" and "Copy OpenPGP security info" - the other four lines are greyed out. Clicking "OpenPGP security info" gives a pop up box with just "OpenPGP security info" written in it. I'm using keys that have ultimate validity to me.

    Regards,

    Bob

    Thanks a lot. I can reproduce the yellow box saying "Unverified signature; click on 'Details' button for more information". I'll look further into the matter.

    The corresponding english message is "WARNING: signature digest conflict in message"

    If you search the web, you'll end up with quite some hits (e.g. http://www.mozdev.org/pipermail/enigmail/2009-December/011821.html). It basically boils down to the fact that the indicated hash algorithm in the header is not the one used to produce the signature (which is absolutely necessary). I'm not sure how to fix this on the outlook side, as I'm not using this. Maybe a posting on the gpg-users mailinglist can give you more help.

    OK, I'll take that information and see if the chaps at the Outlook end can shed any light on the problem. Thanks.
