Overview

rsz

Retrieve ECDSA signature R,S,Z values from blockchain rawtx or txid.

Info

The script parse the data of rawtx to fetch all the inputs in the transaction and reconstructs the unsigned message for each of them to find the Z value. The result is given as R,S,Z,Pubkey for each of the inputs present in the rawtx data. [No Internet required]

If txid is given, instead of rawtx then blockchain API is used to fetch the details of rawtx and then R,S,Z calculation starts. [Internet required]

Usage: Python 3

python getz_input.py

Run

usage: getz_input.py [-h] [-txid TXID] [-rawtx RAWTX]

This tool helps to get ECDSA Signature r,s,z values from Bitcoin rawtx or txid

optional arguments:
  -h, --help    show this help message and exit
  -txid TXID    txid of the transaction. Use Internet to fetch rawtx from
                given txid
  -rawtx RAWTX  Raw Transaction on the blockchain. No internet required

Enjoy the program! :) Tips BTC: bc1q39meky2mn5qjq704zz0nnkl0v7kj4uz6r529at
