#278 Repeated Password Requests after Waking up from Hibernate/Standby

[Oliver Hummel]

I've been having this bug on two different Windows 7 Laptops for quite some time (i.e. during various versions already). The problems is when the machine wakes up from hibernate or standby and an encrypted mail is received, Enigmail asks for the PGP password over and over again.

When you are lucky, after two or three times entering the password correctly, the input box disappears and the mail is decrypted. However, in most cases, the input keeps appearing over and over again and neither entering the password nor closing the input Window shows any effect. It just appears over and over again.

Finally, I have to close down Thunderbird and to kill often numerous instances of gpg.exe in the task manager.

I think, I've sometimes noticed the same behavior when I did not react on the password input request popping up when an encrypted mail is received for some time.

I hope this information is enough to reproduce and eventually fix the bug. Please feel free to contact me if any questions should arise.

Would you please generate an execution trace. You can either obfuscate
private information and post it here, or you can send it to Patrick
(patrick at enigmail dot net) or me (ludwig at enigmail dot net).

Yes, I'll try it, just might take a few days until I find the time...

Cheers

Ludwig,

I have one good and one bad news. ;-)

The good news is, after my update to Thunderbird 24.6 the password
entering windows does not seam to appear anymore unsolicitedly
http://www.dict.cc/englisch-deutsch/unsolicitedly.html on my two
computers.

The bad news is that I was not able to create a trace file on both
computers either... I entered a path as described, even restarted
Thunderbird or the whole machine. Nothing...

Best,

Oliver

I encounter similar behaviour, but only upon wakeup from standby. But in my case, this seems to be a GnuPG or Card reader/driver issue arising from handling of the OpenPGP SmartCard holding my primary key.

After entering my passphrase and a just short standby (passphrase cache still valid), Enigmail displays "Fehler - Überprüfung der Unterschrift fehlgeschlagen; klicken Sie auf "Details" für weitere Informationen " and I see this in the Enigmail log file:

01 [GNUPG:] SC_OP_FAILURE
02 [GNUPG:] ENC_TO ...
03 gpg: verschlüsselt mit ...
04 [GNUPG:] NO_SECKEY ...
05 gpg: verschlüsselt mit ...
06 gpg: Entschlüsselung mit Public-Key-Verfahren fehlgeschlagen: Karte nicht vorhanden
07 [GNUPG:] ERROR pkdecrypt_failed 112
08 [GNUPG:] BEGIN_DECRYPTION
09 [GNUPG:] DECRYPTION_FAILED
10 gpg: Entschlüsselung fehlgeschlagen: Kein geheimer Schlüssel

The important part is the first line (which results in the non-machine-parsable output on line 6. Line 10 is not 100% accurate, since there is a secret key but it could not be accessed properly. Subsequent attempts to decrypt do work as expected, but ask for the passphrase again.

After entering my passphrase and a standby time longer than my passphrase cache period, I first get asked for the passphrase but still receive the same error so that I have to view a different message and enter the passphrase a second time upon returning to the encrypted message.

Oliver, could you please test with a recent nightly build of Enigmail? https://www.enigmail.net/download/nightly.php

[Patrick Brunschwig]

I think this is fixed with Enigmail 1.96. Enigmail would no longer try to decrypt messages that are not displayed.
