Update 2013-11-30: Bounty claimed. Thanks everyone. Another day, another lost password. The code I've pasted below is my (very crude) attempt at modifying bitaddress.org (v 2.4) to help me recover a password in a particular way. In my particular case, I know the exact length of my password, and pretty much know what every letter is, however I'm stuck on the case of some of the letters. Example: I don't know if my password is appLe or aPple or ApplE. In this case, there are 2^X possible combinations, where X is the number of characters whose case I'm unsure of. If you save the below code as .html and check out the brainwallet tab, you'll see I've modified this page to take each character as a separate input. Example: a p p l e I've set it up so that for each character, I can type all the different possible combinations for that character, and then the script will check all the possible combinations of the password. Example, I input: a pP pP l e And it will check: apple apPle aPple aPPle What it's checking against, is the 'target' address. I paste in that target address input box the bitcoin address that I'm trying to find the key for. When the script finds a match, it will output the passphrase that resulted in the address, and output the private key for it too. Now the part I'm stuck on, and what the bounty is for:Any more than about 20 combinations makes my browser hang, because of the horrible way I've done all this in nested while loops. What I need is for this whole thing to be modified so that the browser doesn't hang, and constantly outputs where it's up to. Example: Checking combination 75 out of 8192 I'd like it to kind of act like how the 'bulk wallet' generator tab works, when you generate a huge amount of addresses (say 1000). You can see it working, and doesn't hang the browser.

Your link isn't much help as it's thousands of lines of code (why don't you just paste your relevant function rather than the whole of the bitaddress.org webpage that presumably includes your code "somewhere" inside) - but basically you will want to use a timer function for your looping. Here is a simple timer example: var auto_refresh_seconds = 30;
function auto_refresh( )
{
if( auto_refresh_seconds == 1 )
window.location.replace( window.location );
else if( auto_refresh_seconds > 0 )
{
auto_refresh_seconds -= 1;
setTimeout( "auto_refresh( )", 1000 );
}
}
function load( )
{
auto_refresh( );
}

Good idea, although I'm so embarrassed by my lack of array usage  OP updated.As far as timer usage goes, you're very likely correct that it needs some kind of setTimeout(), however I can't get my own head around how to do it yet. Willing to pay some Javascript guru for the help. |

I think the main issue is that you are using iteration instead of recursion. If I have time I'll post up a sample that'll help you fix it.

As schalk said, your main issue is using iteration instead of recursion. Here's a much better approach. First, you'll need some understanding of what is meant by a "graph" in CS. A graph is an organization of nodes and edges. The nodes contain data or represent state, and the edges represent connections between pieces of data or transitions between states. (Apologies if you knew this already, but I figured you were looking for a full explanation.) For our purposes, think of each letter in the word as a node, and the edges connect in the obvious way, from the first letter to the second, etc. We're going to search the graph for the correct sequence. For simplicity, let's say that our starting node is empty. Let's pretend your password is some upper/lower combo of abcde, in that order. So our blank node has two edges, leading to a and A. a has two edges, leading to b and B A has two edges, leading to b and B We'll be using a concept known as depth first search. Essentially, we're going to dive down to the bottom of the graph, because those are the only valid solutions in our case. Assuming you're familiar with how recursion works, you'd have a function that takes a string and a position, where the position refers to the index of the next character to be appended to the string. When the index is past the end of the string, you have a possible password and you should try it. If not, you return from the function and it unwinds up the stack. A third parameter would be helpful - a boolean representing whether it should be upper or lower. So you call your search function from the implicit blank node, pass in an empty string, 0, and true - then call it again with an empty string, 0, and false. That will search the entire graph of upper and lower combinations. Let me know if this is the kind of advice you were looking for! |

Here is some code that will allow you too check using recursion:
function test(target, current, characters, index)
{
if (index == characters.length)
{
if (current == target)
{
console.log("found");
}
return;
}
var currentLetters = characters[index];
for(var i = 0; i < currentLetters.length; i++)
{
test(target, current + currentLetters[i], characters, index + 1);
}
}
// get pass character elements
var characters = [];
var index = 1;
while ($("input[type=text][tabindex='" + index + "']") !== null) {
var value = $("input[type=text][tabindex='" + index + "']").value.toString().replace(/^\s+|\s+$/g, "");
if (value != "") {
characters.push(value);
}
index++;
}
console.log(characters);
var target = document.getElementById("targetaddress").value.toString().replace(/^\s+|\s+$/g, "");
var current = "";
console.log(target);
test(target, current, characters, 0);

Thank you for your reply schalk and KieranJones1. Yes, the above was a quick and dirty copy/paste job. I'm familiar with recursion but just feel like paying someone else to do this at the moment rather than spend time on it. As the issue involves my own personal money, I feel too emotionally involved to want to code this myself right now. I've tried 2048 combinations with no luck, but need a more solid solution that will help me test about 8 or 16m. Again, anyone able to provide me with a complete solution (rather than just coding help) will be well rewarded. |

You never explicitly asked for code, just "help"  No problem, though, I hope my explanation helped rather than confused things. |

http://pastebin.com/P2ghHZrg# full solution Please tip 18xavJxp7Wxs3vjQvLAsfpTyt9RDBin4RB if you are satisfied with the solution EDIT: Sorry just read your previous post about it needing to have the ability to do 16million combinations. I'm unsure if my solution is capable of that. I think you'd be better off with a desktop application solution as opposed to a javascript one if you're planning on generating upto 16 million bitcoin addresses.

I think you'd be better off with a desktop application solution as opposed to a javascript one if you're planning on generating upto 16 million bitcoin addresses. Why would it be incapable of a particular number? The main point is that I should be able to see it's progress without the browser hanging. If I have no success with 16m, I may even have to go back and try doing a 64m or 128m run... depending on how things go. I'll take a look at your code now anyway, thank you so much for your efforts. |

Here's my solution http://pastebin.com/NWc2rWWrDoes what you asked for, it does not cause the browser to hang. Updates the combinations, it won't show every increase in text area, due to the code seemingly going to fast for JS to actually constantly update the text area value, but i added code so the progress shows up in your console, in real time. So if you go to web developer tools, and console, you'll see realtime data. |

I'm doing 6M combos at the moment, note, it will take about 30 seconds for it to start up, when doing this many combos. More for 16M ofc. EDIT: Something odd happened lol, once I passed 5000, the textarea actually updates in realtime now, and console is lagging lol. So you might even wanna consider commenting out the console.log code I added. EDIT2: What happened was my console window actually got too full, once i closed and reopened it, it was showing realtime too. Browser does not hang . |

Hi schalk, The only thing yours is doing for me, is posting a javascript alert() saying 'done', at the end of it's run. It is not updating me on the progress of how many have been checked as they're being checked. Did you take a look at how the 'bulk wallet' generate tab works, as suggested in the OP? I will now take a look at tubbyjr's solution. Thanks. |

Hi Tubby, Your progress alert is working how I'd expect, however your code doesn't seem to be actually checking each address against the target. Once the target address is found, it should stop processing and show what phrase generated that address. I tried your code with the following phrase: abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuv The real bitaddress.org says the address for that is 1KVGuANp3HyH4m6xQYhUV9EWhq6tUVypAG So, in your html, I input: a b c d e f g h i j k l m n o p q r s t u v w x y z a b c d e f g h i j k l m n o p q r s t u abcdefghijklmnopqrstuvwxyz 1KVGuANp3HyH4m6xQYhUV9EWhq6tUVypAG There are 26 combinations in the above, but your code tries all 26 of them with no 'success', whereas it should have found success on the 23rd 22nd attempt. My originally supplied code in the OP does properly check the target address and stop processing at that point, so this is functionality that you have broken or removed in your version. If you can put that functionality back in, the bounty would be yours. Thanks very much. |

Ugh, yes unfortunately I just noticed that :S. I'm trying some workarounds right now to fix it, it's 4:30 am here :p, may be going to sleep soon, but if it's still up for tomorrow, I'll definitely jump on it.

EDIT2: What happened was my console window actually got too full, once i closed and reopened it, it was showing realtime too. Browser does not hang . I can reproduce that experience It would be cool if this console (on Chrome at least) could be set to only display a certain number of lines and discard the earlier lines! Limiting the console window to 1000 lines or something would be handy. p.s. On my i7 2600k, doing 8m in Javascript should take about 39 hours. Not great, but at least it's not 39 years. If it turns out I need to check more than 8m, I'll probably start hunting for a c++ (and gpu) solution. |
