Question

我想将像下面这样的十六进制文件转换为Binary文件，但出现此错误：我想我需要使用.strip（）方法，但我不太确定！

Traceback (most recent call last):
  File ".\descrypt.py", line 27, in <module>
    main()
  File ".\descrypt.py", line 23, in main
    HexDataBin = HexToBin(HexDataOutput.strip())
  File ".\descrypt.py", line 11, in HexToBin
    binary_string = binascii.unhexlify(HexString)
binascii.Error: Odd-length string

这是十六进制文件：

这是我的代码：

import binascii

def ReplaceHex(HexString, toReplace, newString):
   for elem in toReplace:
      if elem in HexString:
         HexString = HexString.replace(elem, newString)

return HexString

def HexToBin(HexString):
   binary_string = binascii.unhexlify(HexString)
   return HexString

def main():
   with open('target.txt', 'r') as HexFile:
      HexData = HexFile.read()

      print(HexData)

      HexDataOutput = ReplaceHex(HexData, [',', '\\'], " ")
      print(HexDataOutput)

      HexDataBin = HexToBin(HexDataOutput.strip())
      print(HexDataBin)

if __name__ == '__main__':
   main()

您还需要过滤空格符号：

import binascii
from functools import reduce

with open('target.txt', 'r') as text:
    repls = [',','\\','\n',' ']
    # remove all symbols form repls in file content
    hexline = reduce(lambda a, v: a.replace(v,''), repls, text.read())
    binaryline = binascii.unhexlify(hexline) 
    print(binaryline)

十六进制到Bin：binascii.unhexlify的奇数字符串错误
