Title: Is there minimal cpp code which can generate bitcoin WIF and address from sha256 Post by: btctousd81 on December 03, 2017, 10:19:10 AM Is there minimal cpp code which can generate bitcoin WIF and address from sha256 private key?
I am trying to generate Bitcoin WIF key Bitcoin Addresses from sha256 HEX private key. but all i see there are bulky libraries and software packages. I am looking for lightweight small, fast, cpp code which can generate I need this Code: WIF KEY : 5HpHagT65TZzG1PH3CSu63k8DbpvD8s5ip4nEB3kEsreAnchuDf i have this Code: sha256 HEX key : 0000000000000000000000000000000000000000000000000000000000000001 Thanks for your time.

You could try to convert it to C. :) I have also edited that and made my own version, that can do addresses with compressed public keys. I can post it here if you are interested.

I can post it here if you are interested. please do , i am really interested., thanks i am specifically looking for c,cpp because of performance issue., i have php code and it takes around 34 seconds to generate 128 pairs of private key and btc address., and if i add compressed address generaton too, then it takes 67 seconds., its very slow., so i am looking for fastest method out there., i am even looking at how can i use secp256k1 for the same., Title: Re: Is there minimal cpp code which can generate bitcoin WIF and address from sha256 Post by: aplistir on December 03, 2017, 12:00:03 PM I just re-read my comment and realized that it can be understood that I have made my own c++ implementation. BUT I meant I have just edited the python code, not converted it to c++.
Here is a link with some c++ code: https://stackoverflow.com/questions/17672696/generating-bitcoin-address-from-ecdsa-public-key (https://stackoverflow.com/questions/17672696/generating-bitcoin-address-from-ecdsa-public-key) Edit: Also tried to post my version of the python code, but the forum prevented me from posting it. Quite surprising. But doesnt matter, because you were not looking for python code anyway. Code: This website is using a security service to protect itself from online attacks.

My Python version is 2.7.13 It generates 10 Addresses every time it is run. For the first address it also displays the 256 bit random number and public key In the end there is some commented code, to make an uncompressed address, and where you can manually add your own random number and it makes address form that Title: Re: Is there minimal cpp code which can generate bitcoin WIF and address from sha256 Post by: btctousd81 on December 03, 2017, 01:54:39 PM Here is my version of the python code: https://pastebin.com/19y9pUg5 (https://pastebin.com/19y9pUg5) It works for me.

Of course I don't mind, just a pity that I didn't write "python 2.7" to the comments in the beginning of the code. But I guess it is obivious, because the print commands do not have parentheses in them... |
