Bitcoin Tool Kit (or BTK) is a Live Linux (bootable from USB Stick or CD-Rom) which proivides different Tools to manage your Bitcoins in an secured enviroment. It tries to only use stock-software and I provide the step-by-step guide, how to build it on your own, so you don't have to trust me, that I didn't backdoor it.
- Based on Debian (NetInstall)
- Graphical Interface: LXDE
- Browser: midori
- gpg/gpa
- tor
- Electrum Wallet (Lightweight Desktop Bitcoin-Client - http://electrum.org)
- Armory (Bitcoin-Client, able to sign offline transactions - )
- BitAddress.html (Tools for generating Paperwallets, working with Private/Public Keys - http://www.bitaddress.org)
- Blockchain.info Backup Decrypt Tool (https://blockchain.info/DecryptWallet.html)
- ZBar (Scan QR Codes with a WebCam - http://zbar.sourceforge.net/)
- SX (Commandline Tools for lowlevel Bitcoin Actions, experts-only - http://sx.dyne.org/)
I can't vouch for any software I recommend here to be secure and backdoor-free.
Further I can't guarantee for the proposed setup to be the most secure and/or
robust. I tried to be as cautious as possible.
This is only a guideline to help you getting started - everything happens on your own risk.
host#> command specifies a command which gets executed in the build-environment
btk#> command specifies a command which gets executed in the bitcoin-tool-kit environment (inside virtualbox)
If there is a multiline-command, I only write the shell-token once, so you can easily copy-paste it
-
A working Linux Distro (I use Ubuntu 13.10)
-
Connection to the internet, while installing the different tools
-
VirtualBox, wget, other tools
host#> sudo aptitude install virtualbox wget -
An USB-Stick, a CD-Rom or any other bootable medium to install BTK to
-
BKT should be able to run on any linux-compatible platform. Any PC, Notebook or Netbook. Maybe later I will try to bring it to RasperryPie
Here follows a step-by-step guide, how to build your own BTK-bootable Linux from scratch, so you can be sure to get an untempered install.
If you want to take a shortcut, you can download prebuild images from here: PUT_URL_HERE...
Step 1) Invent the universe (should be already done)
Step 2)
Create a working directory
host#> mkdir ~/btk; cd ~/btk
Step 3) Download Debian NetInst http://cdimage.debian.org/debian-cd/7.2.0/i386/iso-cd/
host#> wget http://cdimage.debian.org/debian-cd/7.2.0/i386/iso-cd/debian-7.2.0-i386-netinst.iso
Step 4) Create a new Virtual Image in virtualbox
host#>
VBoxManage createvm --name "btk" --register
VBoxManage modifyvm "btk" --memory 1024 --acpi on --boot1 dvd
VBoxManage modifyvm "btk" --nic1 bridged --bridgeadapter1 eth0
VBoxManage modifyvm "btk" --ostype Debian
VBoxManage createhd --filename ./btk.vdi --size 10000
VBoxManage storagectl "btk" --name "IDE" --add ide
VBoxManage storageattach "btk" --storagectl "IDE" \
--port 0 --device 0 --type hdd --medium ./btk.vdi
VBoxManage storageattach "btk" --storagectl "IDE" \
--port 1 --device 0 --type dvddrive --medium debian-7.2.0-i386-netinst.iso
#Start the VM
VBoxManage startvm btk
Step 5) Follow the Debian-Install (I used the Text-Based one) with defaults to install the Debian NetImg inside the new VirtualBox Image.
Some notes on settings:
*) Language/KeyMap: As you like
*) Hostname: btk
*) Domain: btk
*) Root-Password: As you like, but remember it (not really security relevant)
*) User: btk
*) User password: As you like, but remember it (not really security relevant)
*) Timezone: As you like
*) Partition: <Guided, Use entire disk>, <All files in one partition>
*) Wait for the install to finish
*) Mirror: As you like
*) At the "Choose Software to install" step, only select following points:
"Laptop" and "Standard system utilities"
Step 6) Reboot the new virtual machine and login as root
Initialize the base system with LXDE and other tools
root@btk#>
apt-get update
apt-get upgrade
apt-get install lxde wget midori git dpkg-sig gpa
# set LXDE as default GUI, check that "startlxde" is selected
update-alternatives --config x-session-manager
# and start it at boot
update-rc.d lightdm defaults
# LXDE starten
/etc/init.d/lightdm start
Step 7) (optional) Install VirtualBox ClientExtensions (for better Performance inside the VM)
In the VirtualBox Window, click on "Devices" > "Install Guest Additions"
Open a root-terminal
root@btk#>
apt-get install build-essential module-assistant
m-a prepare
mount /media/cdrom
sh /media/cdrom/VBoxLinuxAdditions.run
Step 8) Bitcoin related Tools/Programs
Open a normal terminal - basefolder
btk#>
cd ~/Desktop
mkdir BitcoinTools; cd BitcoinTools
Open a root terminal - general tools
root@btk#>
apt-get install qrencode zbar-tools
Step 8.1) BitAdress.org
Open a normal terminal
btk#>
cd ~/Desktop/BitcoinTools
wget https://raw.github.com/pointbiz/bitaddress.org/master/bitaddress.org.html
# check if the checksum is in the changelog:
wget -o/dev/null -O- http://www.bitaddress.org/pgpsignedmsg.txt | \
grep -P2 `sha1sum bitaddress.org.html` - || echo CHECKSUM FAIL
Step 8.2) Blockchain.info Wallet Recovery Tool
Open a normal terminal
btk#>
cd ~/Desktop/BitcoinTools/
wget https://blockchain.info/DecryptWallet.html
mv DecryptWallet.html Decrypt_BlockchainInfo_Wallet.html
sha1sum Decrypt_BlockchainInfo_Wallet.html | grep 50451490e0e5ac571b5ff0c6c52cb5c47440fbd5 || echo CHECKSUM FAIL
Step 8.3) SX
Open a root terminal - install/compile the sx-toolset
root@btk#>
cd /tmp
wget http://sx.dyne.org/install-sx.sh
bash ./install-sx.sh
Open a normal terminal - install a nice offline copy of the documentation (optional)
btk#>
mkdir ~/Desktop/BitcoinTools/doc; cd ~/Desktop/BitcoinTools/doc
wget -m http://sx.dyne.org/index.html
mv sx.dyne.org/ sx_doc
Step 8.4) Electrum
Open a root terminal
root@btk#>
apt-get install python-qt4 python-pip
pip install http://download.electrum.org/Electrum-1.9.2.tar.gz#md5=0666168901b7aa2c0d7cf42947966ceb
Step 8.5) Armory
Open a root terminal
root@btk#>
cd /tmp
wget "https://bitcoinarmory.googlecode.com/files/armory_0.88.1-beta_OfflineBundle_Ubuntu-10.04-32bit.tar.gz"
tar xf armory_*
cd Armo*
gpg --recv-keys --keyserver keyserver.ubuntu.com 98832223
dpkg-sig --verify *.deb
./Install_DblClick_RunInTerminal.sh
# some dependencies are unmet - force install of missing packages
apt-get install -f
Step X) Generate a Live-Enviroment via Linux Live Kit (http://www.linux-live.org/)
Open a root terminal
root@btk#>
apt-get install squashfs-tools
cd
git clone https://github.com/Tomas-M/linux-live.git
cd linux-live
#edit config -> set name to "btk"
#(todo, provide own config)
# LIVEKITNAME="btk"
# VMLINUZ=/boot/vmlinuz-3.2.0-4-486
nano .config
./build
