如何纠正TypeError:散列之前必须对Unicode对象进行编码? [英] How to correct TypeError: Unicode-objects must be encoded before hashing?

问题描述

我有此错误:

Traceback (most recent call last):
  File "python_md5_cracker.py", line 27, in <module>
  m.update(line)
TypeError: Unicode-objects must be encoded before hashing

当我尝试在 Python 3.2.2 中执行此代码时:

when I try to execute this code in Python 3.2.2:

import hashlib, sys
m = hashlib.md5()
hash = ""
hash_file = input("What is the file name in which the hash resides?  ")
wordlist = input("What is your wordlist?  (Enter the file name)  ")
try:
  hashdocument = open(hash_file, "r")
except IOError:
  print("Invalid file.")
  raw_input()
  sys.exit()
else:
  hash = hashdocument.readline()
  hash = hash.replace("\n", "")

try:
  wordlistfile = open(wordlist, "r")
except IOError:
  print("Invalid file.")
  raw_input()
  sys.exit()
else:
  pass
for line in wordlistfile:
  # Flush the buffer (this caused a massive problem when placed 
  # at the beginning of the script, because the buffer kept getting
  # overwritten, thus comparing incorrect hashes)
  m = hashlib.md5()
  line = line.replace("\n", "")
  m.update(line)
  word_hash = m.hexdigest()
  if word_hash == hash:
    print("Collision! The word corresponding to the given hash is", line)
    input()
    sys.exit()

print("The hash given does not correspond to any supplied word in the wordlist.")
input()
sys.exit()

推荐答案

它可能正在寻找wordlistfile中的字符编码.

It is probably looking for a character encoding from wordlistfile.

wordlistfile = open(wordlist,"r",encoding='utf-8')

或者，如果您是逐行工作:

Or, if you're working on a line-by-line basis:

line.encode('utf-8')
