The beauty of this process is that all those private keys you generated for the Neo Paper Wallet public key generator by snowypowers via bitcoin private keys.
These can be regenerated with just the 12 or 13 words from the bitcoin Electrum wallet which YOU can generate with dice rolls.
It creates a simple generation and management of Neo Private keys and no disclosure of the private key until you want to transfer NEO back to an exchange.
I’m on Linux which is good but I did get hacked via Teamviewer once and actually saw the person on my PC. I had recycled a password in the dim and distant past from the linkedin hack…
What saved me even if I hadn’t been in the office was 2FA on all my accounts… Live and learn fast!
However as far as I know the official Neo Web Wallet @ https://neowallet.cn/ allows you to send without re-entering your password like say electron. This is a real over sight.
Now I’ve gone over to the Neon City of Zion wallet and use kde-connect to securely pass my private key I scan as a paper QR code on my phone to pc clipboard, which I then paste into the Neon City of Zion wallet.
What would be cool for both wallets is allow you to enter either a 12 word passphrase which you could generate in electrum for example OR your private key.
You can for example user electrum to generate your 12 word passphrase and use one of the private keys generated from your addresses as a Neo/Neon private key.
Part One Installation bitcoin Electrum
On the “official installation page”
sudo apt-get install python-qt4 python-pip
sudo apt-get install python-qt4 python-pip python-setuptools
I have contacted the maintainers of this page and got nowhere, so I have no idea how the average Joe succeeds in installing it at the moment.
Step TWO Generate your passphrase
Follow the instructions below or just create a new wallet with Electrum which will generate a 12 word passphrase for you
Rolling the dice
wget -O dice2key.zip https://github.com/swansontec/dice2key/archive/master.zip unzip dice2key.zip cd dice2key-master
51 dice rolls – the dice2key software will now warn you it’s not 100, but we’re not using it for the actual key, just the entropy, but more than 51 rolls in Electrum v2.4 creates a seed phrase greater than 13 words.
mark@asrock:~/dice2key-master$ ./dice2key.sh 123456123456123456123456123456123456123456123456123 warning: The input has less than 100 dice rolls4. Download Neon Wallet by CoZ 91D89C79009852800BFFCCDC406B1BA0
Next we need the number for Electrum as a decimal not hex, which we can do from the command line:
mark@asrock:~/dice2key-master$ echo "ibase=16; 91D89C79009852800BFFCCDC406B1BA0"|bc 193862769152946304546066490817889639328
Go to the command line, NOT the console within electrum and run
electrum make_seed --entropy=193862769152946304546066490817889639328
It will generate a SEED PHRASE with thirteen words like:
useless welcome frame safe door scrap lock swear frame height hotel endless depth
[Or you can remove a few numbers from the end IE 39328 and get a standard 12 word passphrase
electrum make_seed --entropy=1938627691529463045460664908178896 must student hungry bike parade boring frown sell detail agent tiny matter
Having spoken with Thomas Vögtlin Electrum’s author on IRC, more entropy does not result in a more randomly generated private key:
< > Hullo anyone, electrum make_seed –entropy=XXXXXXX can generate a seed of MORE than 13 words, will this cause a problem in the future? or does it not matter – Cheers> m1bxd: notes<
Then you can run electrum
-> Give the wallet a name 2017-08-19 NEO1
-> Standard Wallet
-> “I already have seed”
must student hungry bike parade boring frown sell detail agent tiny matter
Go to “View”->”addresses”
-> choose a bitcoin public key
-> Right click
Pick a key pair and use the private key as you Neo / Neon private key.
Now do a couple of things click on the QR link above close
Go to go Copy – go into LibreOffice Writer paste it into a new document
Then go back and copy the private key IE
Next head over to https://github.com/CityOfZion/neon-wallet/releases
And grab you Neon wallet, if you are on Linux/Ubuntu don’t forget to make the
Linux.Neon-X.X.X-x86_64.AppImage – EXECUTABLE
And paste in the private key we derived from the bitcoin key pair because we can use this in Neon Wallet by CoZ or the official wallets.
We can use this to optionally double check
Now the Neon CoZ wallet has generated the NEO public key
From the bitcoin private key which you now regenerate from the 12 word passphrase electrum. In fact off the bat you could have generated 20 NEO private keys.
Paste this public key on your LibreOffice Writer page. As well as the NEO public key, print it a few times along with the public key & private key QR codes and12/13 word electrum passphrase.
At the end DO NOT SAVE this page. Only print it ou.
