Create password breaker for iPhone backup files

I lost all my photos and contacts in my iPhone, when I had to do a recovery, after I did an update. When trying to restore my old data from backup file, it prompted me for password. I have tried all passwords I normally use, but to no availe.

I have tried programs like Elcomsofts password breaker. The problem is that they only allow you to search for either words from a dictionary, or the letters/numbers you tell it. But you can not (not that I have found at least) create some kind of regular expression to limit the search.

I have am pretty sure I know the structure of my lost password = A combination of words and random letters/numbers. So I think that a regular expression could make it realistic to get the password. So this is why I turn to you.

I am trying to create a simple program in .NET, C#. A console application, or a basic MVC-application. An application where I would loop through all the combinations my regular expression would come up with. That part I think I know how to do. The problem is:

How can I test the backup file/folder with the passwords? I have tried to open the file using Process.Start(filepath), but when I point to the plist file, it says there is no program to open the file with. And even if I manage to open the file with say Notepad, how do I test the password? Is it a parameter to send in? And what kind of reply will I get back? I mean how do I know if a password is a match or not?

In short: I need to create a program (or find one that works), that can loop through a regular expression limited list of passwords, and try if they match the one in my iPhone backup file.

I am sorry that my question is long and a bit untechnical. I am a bit new to this. I have done webbpro开发者_StackOverflow社区gramming, but not much windows/file related programming. Any help you might be able to give would be highly appreciated, as I am a bit desperate to get photos of my daughter and contact info back.

See if Elcomsoft allows you to wipe out the dictionary and provide your own. Then, generate all of the possibilities and make that your dictionary.
