<p>Two things that might be responsible:<br>
1.) The email goes through some Microsoft Exchange server<br>
2.) It's somehow updated/changed by the mail server before being
delivered</p>
<p>Unfortunately we don't have the resources to help you with
Enigmail problems.<br>
I think it's best if you bring it up with them.<br>
If it should be the case that this is related to our version of
MacGPG, what I doubt however, you're welcome to come back to us
anytime :)</p></div>Luke Letag:gpgtools.tenderapp.com,2011-11-04:Comment/216143892012-12-17T13:48:18Z2012-12-17T13:48:19Z"Error - signature verification failed"<div><p>Hi,</p>
<p>I have a similar but appears to be slightly different problem. I
have been using Thunderbird on a mac with OpenPGP encryption for 2
months to exchange email with another engineer. Everything was
working fine until yesterday when i got the following error when i
tried to open a message from this same engineer:</p>
<p>penPGP Security Info</p>
<p>Error - signature verification failed</p>
<p>gpg command line and output:<br>
gpg<br>
gpg: problem with the agent: End of file<br>
gpg: encrypted with 4096-bit RSA key, ID DFB360CE, created
2012-05-18</p>
<pre>
<code> "Sxxxxx Rxxxxxx <xxx@gmail.com>"</code>
</pre>
<p>gpg: encrypted with 2048-bit RSA key, ID 0DBFB63B, created
2012-06-16</p>
<pre>
<code> "Karthik Muthukrishnan <xxxxx@yahoo.com>"</code>
</pre>
<p>gpg: public key decryption failed: Operation cancelled<br>
gpg: decryption failed: No secret key</p>
<p>I do have the public and private keys loaded up..</p>
<p>Can someone help ?</p>
<p>Thanks.</p>

<p>hmm... I think that the sender might have used a different
public key of yours to encrypt the message to, which you no longer
have the private key for.</p>
<p>Could you check that the key id messages?</p></div>Luke Letag:gpgtools.tenderapp.com,2011-11-04:Comment/216143892012-12-17T16:44:21Z2012-12-17T16:44:21Z"Error - signature verification failed"<div><p>Luke,</p>
<p>I have a cache of older messages that have been encrypted that
now have<br>
the same problem. So, I don't think the problem is on the sending
side...</p>

following command:</p>
<pre>
<code>killall gpg-agent</code>
</pre>
<p>Otherwise it's easiest to reboot the machine. Let me know if
that changes anything.</p></div>Luke Letag:gpgtools.tenderapp.com,2011-11-04:Comment/216143892012-12-17T16:50:01Z2012-12-17T16:50:01Z"Error - signature verification failed"<div><p>yes, that fixed it, thanks a lot !!</p></div>karthik.muthukrishnantag:gpgtools.tenderapp.com,2011-11-04:Comment/216143892012-12-17T16:52:01Z2012-12-17T16:52:01Z"Error - signature verification failed"<div><p>Pretty strange you started seeing it in the first place
though.<br>
Could you please check your Console.app log for any errors related
to gpg-agent or gpg and send them to team @ gpgtools.org?</p>
<p>Thanks!</p></div>Luke Letag:gpgtools.tenderapp.com,2011-11-04:Comment/216143892012-12-17T19:21:15Z2012-12-17T19:21:15Z"Error - signature verification failed"<div><p>Luke, i am on a Macbook Pro. Don't see a console app in the
Appstore for<br>
the Mac..</p>
<p>I'll be happy to pass on any diagnostic to help you, please let
me know<br>
what else i can do.</p>

it using Spotlight.<br>
It contains diagnostic messages which might help find the problem
here.</p></div>Luke Letag:gpgtools.tenderapp.com,2011-11-04:Comment/216143892012-12-20T14:54:58Z2012-12-20T14:54:58Z"Error - signature verification failed"<div><p>Luke,</p>
<p>I scoured the logs, on the 15th & 16th dn don't see anything
other than<br>
the routine from other apps. Can you tell me what the prefix of the
logs<br>
would be or what a good search string would be ?</p>
<p>Thanks.</p>

<p>If you don't find anything useful I'd close this discussion
otherwise. Jeff never replied so far and you are now running fine
now, right?</p>

ahead and close the discussion.</p>
