[CLOSED] Java coder to generate a Bitcoin Address using Bouncy Castle

[Xenland]

Please PM me how much something like this might cost, I need a working java code that generates a Bitcoin address that is commented very well. I already understand how it all works as far as cryptogophy goes I just can't figure out java yet

Im' guessing you'll need to use Bouncy castle but not sure if its absolutely required.

I just looked around and found:

https://github.com/jim618/multibit/blob/master/src/main/java/org/multibit/action/CreateNewWalletSubmitAction.java

(Look at line 69.)

Here the actual ECKey class:

Maybe that helps you already...

Thank you for taking the time to check into that for me!

That's just way to much information for me to know "what exactly is required at a minimum to create a Bitcoin address"
Not to mention, It uses a library called Bouncy Castle so every time I write my own implementations, I can't even test it because it no compiles.

Hmmh...but the problem is, that you would get a lot _more_ information, if you comment this code properly.

I checked the algorithm to create the addresses

https://en.bitcoin.it/wiki/Technical_background_of_version_1_Bitcoin_addresses

and I guess the problem is simply, that it's complicated... :-)

So no matter how much comments you add, it's still complicated... :-)

I could walk someone through creating a bitcoin address they just need to write java code. It sound counter intutive but some programmers have the know how just not the bitcoin know how. Im actually doing this for my pseudoclient documentation and so i fully understand how everything works i just need it converted to code and scince im not a pro java programmer i can not accomplish this on my own

(awaiting response from a pm)

Job is still up for grabs tho

There is working javaSCRIPT code to do this in the homepage at bitaddress.org, and it depends on no external code.

It might be a start.

Now there is an idea.....!

Things like

Code:

//This is the base58 function

//We are now sha256(sha256()) hashing now

//RFIMID186 is happening here

Thats all i require.... I don't require "documentation" inside the comments...

Still need a coder

Not java but check out https://github.com/weex/addrgen

^--- Aims to be a minimal single address generator and outputs random {"address","privkey"} pair with commented options to generate from a passphrase, existing privkey, and more.

Thanks Python is usually straight forward. I could always use a python example in my Pseudocode Client Documentation.

I can code Java,  but don't understand the Python code well, so I can't  port it for you ...
