从文件文本转换比特币私钥-逐行 [英] Convert Bitcoin private key from file text - line by line

问题描述

我开始学习Python以使下面的项目成功，但是我需要帮助.

i started learning Python to succeed my project below, but i need help.

我有一些旧钱包的比特币/莱特币私钥.我很确定这些地址是空的，但是在删除此旧文件之前，我想将这些不同的私钥转换为公用地址，以检查是否全部为空.我会使用在线服务一次检查所有这些地址(有些可以控制多达50个地址).

I have some Bitcoin/Litecoin private key of some old wallets. I'm pretty sure those addresses are empty, but before I erase this old file, I would like to convert these different private key to public address to check if all is empty. I would use an online service to check these addresses all at once (some allow control of up to 50 addresses).

我知道，我可以在钱包中一个一个地导入每个私钥，但是我的计算机上没有更多的比特币核，并且我不想安装新的私钥来检查我的地址.

I know, I could import each private key one by one in wallet but I don't have any more Bitcoin-core on my computer, and I don't want to install a new one just to check my addresses.

经过大量研究，我有以下功能代码:

After a lot of research, i have this functional code :

import ecdsa
import hashlib
import base58


with open("my_private_key.txt", "r") as f:    #Input file path
      data = f.readline()
      for line in data:

                  #Convert hex private key to bytes
         private_key = bytes.fromhex(data)      

                  #Derivation of the private key
         signing_key = ecdsa.SigningKey.from_string(private_key, curve=ecdsa.SECP256k1)
         verifying_key = signing_key.get_verifying_key()

         public_key = bytes.fromhex("04") + verifying_key.to_string()

                 #Hashes of public key
         sha256_1 = hashlib.sha256(public_key)
         ripemd160 = hashlib.new("ripemd160")
         ripemd160.update(sha256_1.digest())

                 #Adding prefix to identify Network
         hashed_public_key = bytes.fromhex("00") + ripemd160.digest()

                 #Checksum calculation
         checksum_full = hashlib.sha256(hashlib.sha256(hashed_public_key).digest()).digest()
         checksum = checksum_full[:4]

                 #Adding checksum to hashpubkey         
         bin_addr = hashed_public_key + checksum

                 #Encoding to address
         address = str(base58.b58encode(bin_addr))
         final_address = address[2:-1]

         print(final_address)

         with open("my_addresses.txt", "a") as i:
            i.write(final_address)

我有两个问题:

1. 计算私钥->地址工作正常，但仅处理输入文本文件的第一行.
2. 第一行处理了65次，因此我的输出文件包含65次从我的第一个私钥生成的相同地址.在Python解释器中，也会出现65次.

我了解 f.readline()逐行读取文件，并且我认为 for数据行:会逐行读取此文件以处理每个文件线.

I understood f.readline() read a file line by line, and I thought the for line in data: would read this file line by line to process each line.

我试图移动变量 data 的位置，但这一次，仅第二行正在处理.

I tried to move the location of my variable data but this time, only my second text line is processing.

with open("my_private_key.txt", "r") as f:    #Input file path
      for line in data:
          data = f.readline()
                         .....

我已经做了很多测试，但是我不知道出了什么问题.我哪里出问题了?

I've done a lot of tests, but I can't figure out what's wrong. Where do I go wrong ??

预先感谢您的帮助.

推荐答案

您在滥用readline()，这只会返回一行.

You are misusing readline() this will only return one line.

不过，您可以仅使用for循环遍历文件中的行，

You can however iterate over lines in a file just with a for loop,

import ecdsa
import hashlib
import base58


with open("my_private_key.txt", "r") as f:    #Input file path
      for line in f:

                  #Convert hex private key to bytes
         private_key = bytes.fromhex(line)      

                  #Derivation of the private key
         signing_key = ecdsa.SigningKey.from_string(private_key, curve=ecdsa.SECP256k1)
         verifying_key = signing_key.get_verifying_key()

         public_key = bytes.fromhex("04") + verifying_key.to_string()

                 #Hashes of public key
         sha256_1 = hashlib.sha256(public_key)
         ripemd160 = hashlib.new("ripemd160")
         ripemd160.update(sha256_1.digest())

                 #Adding prefix to identify Network
         hashed_public_key = bytes.fromhex("00") + ripemd160.digest()

                 #Checksum calculation
         checksum_full = hashlib.sha256(hashlib.sha256(hashed_public_key).digest()).digest()
         checksum = checksum_full[:4]

                 #Adding checksum to hashpubkey         
         bin_addr = hashed_public_key + checksum

                 #Encoding to address
         address = str(base58.b58encode(bin_addr))
         final_address = address[2:-1]

         print(final_address)

         with open("my_addresses.txt", "a") as i:
            i.write(final_address)
