Title: Couple errors in Electrum - possibly encryption related
Post by: eaglejam on April 14, 2013, 06:25:13 PM
I've been having a couple problems with Electrum lately. The first I posted in the newbie's section, with no help. First off, I'm on Mac OS X 10.8.3. So I've been using Electrum 1.7 for a while now (The Executable signed by Animazing is the only one that works), and it has always served me well. I decided to upgrade to 1.7.2 today. I had problems upgrading in the past, so... I deleted everything (I backed up my seeds and Label API Key of course), installed Electrum 1.7.2, restored my seeds, and re-inputed my Label API key. It then said to restart Electrum, I did so, and the GUI errored out, not even to the console like it always points to to find the issue. I had to open it (Electrum) up in the TERMINAL to this: Last login: Thu Apr 4 17:13:57 on ttys000 Eaglejams-MacBook-Pro:~ EJ$ /Applications/Electrum.app/Contents/MacOS/Electrum Traceback (most recent call last): File "/Applications/Electrum.app/Contents/Resources/__boot__.py", line 316, in <module> _run() File "/Applications/Electrum.app/Contents/Resources/__boot__.py", line 311, in _run exec(compile(source, path, 'exec'), globals(), globals()) File "/Applications/Electrum.app/Contents/Resources/electrum.py", line 185, in <module> gui.main(url) File "/Applications/Electrum.app/Contents/Resources/lib/python2.7/gui/gui_classic.py", line 2338, in main w = ElectrumWindow(self.wallet, self.config) File "/Applications/Electrum.app/Contents/Resources/lib/python2.7/gui/gui_classic.py", line 344, in __init__ self.run_hook('init_gui') File "/Applications/Electrum.app/Contents/Resources/lib/python2.7/gui/gui_classic.py", line 378, in run_hook apply(f, args) File "/Applications/Electrum.app/Contents/Resources/lib/python2.7/plugins/labels.py", line 65, in init_gui self.full_pull() File "/Applications/Electrum.app/Contents/Resources/lib/python2.7/plugins/labels.py", line 158, in full_pull if self.do_full_pull(force) and force: File "/Applications/Electrum.app/Contents/Resources/lib/python2.7/plugins/labels.py", line 205, in do_full_pull decoded_key = self.decode(label["external_id"]) File "/Applications/Electrum.app/Contents/Resources/lib/python2.7/plugins/labels.py", line 33, in decode decoded_message = aes.decryptData(self.encode_password, base64.b64decode(unicode(message)) ) File "aes/__init__.pyc", line 632, in decryptData File "aes/__init__.pyc", line 29, in strip_PKCS7_padding ValueError: String ending with '\x7f' can't be PCKS7-padded 2013-04-04 17:27:31.815 Electrum[23076:707] Electrum Error Can any Electrum programmers give me an idea on where to go from here to get this resolved?

I can't use Electrum as intended. Hope this info helps.

Just a guess... Any non-standard characters in your password? Try to restore again, using another password for testing.

No non-standard characters in my password. Just alphanumeric. Tried a new password and it still crashed.
I did more testing, and I think I've found the problem: the bug lies in the "Label Sync" plugin.
I did this in steps:
I restored from seed and I shut down Electrum, without it crashing on startup. I added an API key for the Label Sync plugin, but I didn't check the "turn on" checkmark, I shut it down without Electrum crashing on startup. I checked the checkmark for turning on Label Sync and shut down the client, and then Electrum will crash on startup repeatedly.
I hope that helps making this bug dead.

Could you try a full upload via the plugin settings and trying it again?

I had another theory, 1.7.0 doesn't contain the encryption key stuff for Label Sync, but 1.7.2 and 1.7.3 do. Maybe the Label Sync service was expecting a encryption key that 1.7.0 didn't have in its electrum.dat file
So I backed up my labels via a Screenshot tool, restored from seed, added labels and API key in, forced upload Labels in Label Sync, and shut down Electrum.
When I restarted Electrum, it all worked!

Glad you solved that issue :)
