Title: Need C/C++ code for brain wallet function: any suggestions? Post by: Fizpok on June 04, 2013, 08:55:03 AM Hi,
I am looking for C/C++ code for brain wallet function. What it should look like: 1. C/C++ 2. No dependencies, all code should be in that function or its sub-functions. Alternatively I need a sample project for MSVC 2005 or before (I don't have licence for later versions). The reason is simple: I am not good enough with C++ to handle installation of 10 mutually dependent libraries as it usually happens in Unix :) What it should do: Take ASCII text and produce a private key (the 51 char one, starting with "5"). Technically, this functionality is in pywallet, but it uses Python-specific libraries. Title: Re: Need C/C++ code for brain wallet function: any suggestions?

It's not really that difficult to get OpenSSL integrated (CIYAM Open uses it) so if you don't mind using just the *one* 3rd party library then I would recommend using it to help you to complete your project.

So the important question is: Do you just want to generate a private key based on the user chosen text, or do you want the software to also output the bitcoin address? Generating private key only won't be too bad, but you should really consider using OpenSSL if you want your brain wallet generator to compute the bitcoin address as well.

That's why I asked for a sample project, not just a code snippet... It is a large and complex library, and I don't need 99% of it...

Python bindings too (see main page). Title: Re: Need C/C++ code for brain wallet function: any suggestions?

But htanks for the CYAM, I will try to study it. Title: Re: Need C/C++ code for brain wallet function: any suggestions?
