So it’s been a while since I’ve talked about bitcoin and I’ve recently gotten more interested now that the prices have grown significantly. So I started explaining it to some friends at school and have gotten them interested as well. So of course I wanted a nice and custom key to show off, and it’s really quite easy with tools like vanitygen by samr7 over on the bitcoin forums which is the tool that we will be using for this post.
Because it’s actually doing alot of math to figure out (or more correctly guess) at the key, the longer you want your custom key to be, the longer you will have to crunch these numbers so don’t get too crazy with it.
The tool has several options but most of them won’t be used, in fact I only use one of the possible flags below, but there are more, you can view them by running vanitygen.exe with the “-h” flag, or just save this as something like help.bat in the same folder as vanitygen.exe and double-click the .bat file to run the help command for you.
Now that you have read the options the batch file below might make more sense, we are going to ask you for the pattern you want your custom key to have, and decided if you want it case-sensitive which takes MUCH longer, and might have strings that are not allowed, but it’ll error out if it does so you can try something different.
So save this file as something like vanity.bat in the same folder as vanitygen and run it. (Change the highlighted lines 19 and 23 to reflect the executable you are going to use for your system. (ie: if on a 64 bit system you would use vanitygen64.exe, on a gpu you would use oclvanitygen.exe)
echo You can always press ctrl+c to stop this script from running.
set /p Name=Enter your desiered pattern (The leading 1 has been added for you): 1
set /p ConfirmName=Your pattern will be 1%name% Is this correct [y/n]?:
if "%ConfirmName%"=="" (GOTO GETINPUT)
if "%ConfirmName%"=="y" (GOTO STRICTNESS) else (GOTO EXIT)
set /p Eieye=Do you require your pattern to be CaSe SenSitvE [y/n]?
if "%Eieye%"=="y" (GOTO CASEYES)
if "%Eieye%"=="n" (GOTO CASENO) else (GOTO EXIT)
Here is what the output of the script does (note, I’ve highlighted the user input for clarity, there is no color in the actual script results, and No this key should NOT be used!):
Then create a shortcut on your desktop for vanity.bat and change the icon to something that you prefer, I’ve added the image I use below for fun, and then just run this anytime you (or a friend) want a custom wallet key!
As for wallet’s, I use the Armory wallet but for most users I would recommend multibit as it’s much faster, and much smaller, but you do give up some freedom and security relying on others where armory can offer a true TNO security standpoint, just my 2 bitcents on that topic, now get mining!
