Some of us want to store a sizable amount of bitcoins as a long-term investment or savings. We need a way to store our keys the pieces of data that give us, and only us, access to our coins that will be safe from both loss and theft; but we do not care about them being easily usable on a daily basis.
A great way to do this is paper wallets — storing our keys on printed pieces of paper. This is essentially a program that allows you to create keys and corresponding Bitcoin addresses in an easily printable form.
Ignore the text you see when visiting the page. All browsers have an option to do this, even if differently named. Disconnect your computer from the internet. This is very important. Your secure, offline paper wallet will be of no use if the generated keys are sent to an attacker by malicious software through an internet connection.
Open the file bitaddress. For this, it is best to download a copy of the page. Preferably, you should disable any addons running on your browser, for example, by running in incognito mode. The site contains many different options for generating paper wallets, but I find this one to be the best.
Choose the number of addresses you wish to print e. Use as many as you can fit in a printed page in big enough letters to be easily readable. Connect a printer with a USB cable. Of course you will need a printer for this. Clear your browser cache. This will decrease the chance that your browser keeps the keys. Instructions on how to do this on various browsers is available at http: Reconnect the computer to the internet.
It is safe to do so now with any trace of the keys erased. Store the paper copies in multiple secure locations — a safe in your house, a relative, a safety deposit box, etc. Keep in mind that if a thief that understands Bitcoin gets his hand on one of the copies, the coins are gone.
If all of the papers are lost or damaged to the point of illegibility, the coins are gone. You could send all of them to one address, but there are several advantages not to store too much on a single address. Split the coins however you see fit. You can always add more coins to any of the addresses. You can save most of the addresses you printed for future use. Keep in mind — once you send from an address, it is no longer secure and you will need to store your funds in the other addresses.
Try this option in your client of choice. The most secure method is to import the key into an offline wallet — for example, using Armory. This is fairly complicated now, but hopefully by the time you want to do it, the software and hardware to make it easier will exist. As the title implies, this procedure will allow you to create a reasonably secure paper wallet.
If you do, however, want a more secure wallet, here are some more things you could do:. In theory, the website from which you download the generation software could be hacked and replaced with malicious content.
Use a Linux live CD. Linux is less vulnerable to malware than Windows. This is true regardless of whether the reason is Linux being inherently more secure or hackers not bothering writing malware for it. For example, you can use Ubuntu for this — burn an Ubuntu live CD, and follow the procedure after booting from it. Use a multi-factor system, such as multisig, SSSS or key encryption. You can encrypt your keys before printing them, so that stealing the paper will be useless without the password.
You can place the pieces in different places knowing that several pieces will need to be stolen to compromise the coins. The security of this, however, still relies on the computer in which the key is generated and split and on which it is combined and used.
Using a multi-signature address is more secure, but also more complicated. Not all fonts are created equal. In some it is difficult to tell capital letters from small ones, which may create problems when you try to import the keys.
Choose a clear font. This is more space-consuming, but allows easier import. Use at your own risk! Even with the best security practices there can be failures; and these suggestions aim to balance security with accessibility rather than maximize security.
