461  Bitcoin / Electrum / Re: Electrum 1.9 released on: November 13, 2013, 08:09:27 PM
So I am updating from the 1.8 branch and have a few questions:
- Where do you toggle between expert mode and normal?
no more. everybody shares the same user experience.

Quote
- Gap limit option has been removed, right?
it has been hidden. it was unnecessarily complicated for normal users, and it is not a good method for merchants.

Quote
- The copy option under the file menu is the new way to backup the wallet?
yes

Quote
- Default wallet has been moved under wallets directory. But what about other wallets? They open fine but I want to know whether they will be "upgraded" in future?
they will still be supported. you may move them to your wallets directory

It would be nice if there was a graphical interface for this (maybe like Armory does it).

You can use the Tools > Create transaction > From CSV to send to many addresses at once.
I know and that is what I would use (or console, depends), but having a graphical interface to create a sendmany transaction would help users that have less knowledge about creating Bitcoin transactions.

how would that differ from the CSV input window?

We just released version 1.9.4, with binaries for mac & windows.
This should fix the various bugs reported since 1.9 was launched.

464  Bitcoin / Electrum / Re: Seed entropy on: November 12, 2013, 07:13:50 AM
ECDSA 256 bit key only has 128 bits of security.  Public key systems generally need larger keys to deliver the same key strength as symmetric encryption.  

exactly. for technical details, see the pdf at http://ecc-challenge.info/
465  Bitcoin / Electrum / Re: Key stretching weakness on: November 11, 2013, 10:52:13 AM
I found a small weakness in Electrum's key stretching algorithm: The seed-key is only hashed twice.  This allows rejecting most passphrases before stretching.  It's good for about 8 bits worth of security.

I have sample code here:  https://bitcointalk.org/index.php?topic=85495.msg3546401#msg3546401

Electrum's key stretching is not intended to protect the seed against someone having an encrypted seed and bruteforcing AES.
It is there only to make the seed a bit stronger, in case a user uses a custom seed instead of the 128 bits of entropy provided by the software.

466  Bitcoin / Bitcoin Discussion / Re: electrum showing 2 seperate entries in send transaction only sent one on: November 08, 2013, 11:22:42 AM
Hi
I am using electrum 1.9 client - I sent 0.5 bitcoin - which shows correctly in the History
But right clicing the entry and looking at transaction there are 2 transactions - one for 0.5 and one for 0.788 - in 'Outputs'
I have not sent any other apart from the 0.5 , and only the 0.5 one shows in history - I do not understand what the 0.788 entry is doing there , also the 0.5 has been in 'pending' for 2 hours now ..
very confused and a bit worried ..
Any ideas ?



the 0.788 output is probably your change
467  Bitcoin / Electrum / Re: Electrum 1.9 released on: November 08, 2013, 09:19:32 AM
Not the smoothest of upgrades, that's for sure. Takes a little of the shine off the venerable Electrum  Undecided

indeed, sorry about that.
we are actively working on these issues, and I hope we'll get better binaries next week.
468  Bitcoin / Electrum / Re: Electrum "stuck" - showing unverified transactions on: November 06, 2013, 08:11:26 PM
Its over 24 hours and the transaction is still not verified whats going on?

Edit: Deleted everything to do with Electrum and reinstalled using my seed and now its verified, quite a serious bug.

indeed, you are the second user to report that i gets fixed by restoring from seed.
apparently something was corrupted in the wallet file
469  Bitcoin / Electrum / Re: Electrum 1.9 released on: November 06, 2013, 10:31:30 AM
I also temporarily removed the portable build from the website; it was broken.
apologies for the mishap; I hope we will soon have a fixed build
470  Bitcoin / Electrum / Re: Electrum "stuck" - showing unverified transactions on: November 06, 2013, 10:30:28 AM
Well my first test transfer  completed and verified with no problems within 30 mins. Its only when I transferred the rest of my btc that it wont verify. The transaction is currently sitting at 146 confirmations when I look on blockchain.info. Also now the program wont connect at all it either says not connected or just sits at synchronizing forever...some real help would be greatly appreciated.
please report if you were using the windows portable version of 1.9
it is broken and I removed it from the website
471  Bitcoin / Electrum / Re: Electrum 1.9 released on: November 05, 2013, 10:58:08 PM
I just made 1.9.1 packages, that fix a few regressions: --offline mode, portable mode.
I hope we will soon have binaries from Animazing.
472  Bitcoin / Electrum / Re: Electrum 1.9 released on: November 05, 2013, 10:14:01 PM
ok, if you are reporting a regression, please mention if it occured with the "windows portable" build
473  Bitcoin / Electrum / Re: Electrum 1.9 released on: November 05, 2013, 10:04:00 PM
are the connection problems encountered with portable builds?
474  Bitcoin / Electrum / Re: Somewhat clueless questions about the Electrum seed, and security in general on: November 05, 2013, 06:10:15 PM
The seed is 128 bits long. (which is very strong, because it corresponds, in terms of bruteforce iterations, to the strength of a 256 bits ecdsa public key, not to a 128 bits key)
The seed is encrypted with the user chosen password.

Whenever something needs to be signed (for example if you spend bitcoins), then the seed is temporarily decrypted with the user provided password.
475  Bitcoin / Electrum / Re: Electrum 1.9 released on: November 05, 2013, 06:07:05 PM
Hi, thanks for the update. Was wondering where the dollar value went though? Why did you get rid of it? It was on the bottom left right next to BTC amount.

It is a plugin now. See Menu Tools -> Plugins -> Exchange rate
Electrum can integrate third party applications as plugins.
476  Bitcoin / Electrum / Re: Electrum 1.9 released on: November 05, 2013, 10:26:07 AM
Thanks. Auto-connect was enabled. Internet connectivity is normal, version 1.8.1 seems to be working but not 1.9.

if you click ok, it should work.
otherwise, try to select a server manually...
477  Bitcoin / Electrum / Re: Zeroed balances after restoring wallet on: November 05, 2013, 10:23:55 AM
if you are in trouble, restore from seed.
And what about labels?


EDIT:
I think the problem is that new release of Electrum stores the wallet in "default_wallet" file in "wallets" folder.
So, how to restore the "electrum.dat" file?
Should i open a new topic about this issue?

menu-> file-> open and you can open any file
478  Bitcoin / Electrum / Re: Electrum 1.9 released on: November 05, 2013, 10:23:03 AM
I found some old seeds I had when I first started messing around with Electrum; is there any way to find out if there is anything on them without having to re-install?

no you have to reinstall (unless you want to give the coins away)
479  Bitcoin / Electrum / Re: Electrum 1.9 released on: November 05, 2013, 09:52:20 AM
staring at a red dot when I want to transact just doesn't do it for me.

click on the red dot. enable auto-connect. click OK
480  Bitcoin / Electrum / Re: Zeroed balances after restoring wallet on: November 05, 2013, 09:51:15 AM
if you are in trouble, restore from seed.
