如何纠正TypeError: unicode对象必须编码哈希之前?

我有这样的错误:

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中执行这段代码时:

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()

存储密码(PY3):

import hashlib, os
password_salt = os.urandom(32).hex()
password = '12345'

hash = hashlib.sha512()
hash.update(('%s%s' % (password_salt, password)).encode('utf-8'))
password_hash = hash.hexdigest()

错误已经告诉了你要做什么。MD5操作在字节上，所以你必须将Unicode字符串编码成字节，例如line.encode('utf-8')。

你必须定义编码格式，比如utf-8，试试这个简单的方法，

使用SHA256算法生成一个随机数:

>>> import hashlib
>>> hashlib.sha256(str(random.getrandbits(256)).encode('utf-8')).hexdigest()
'cd183a211ed2434eac4f31b317c573c50e6c24e3a28b82ddcb0bf8bedf387a9f'

存储密码(PY3):

import hashlib, os
password_salt = os.urandom(32).hex()
password = '12345'

hash = hashlib.sha512()
hash.update(('%s%s' % (password_salt, password)).encode('utf-8'))
password_hash = hash.hexdigest()

如果是单行字符串。用b或b把它包起来。

variable = b"This is a variable"

variable2 = B"This is also a variable"

该程序是上述MD5破解程序的免费和增强版本，它读取包含散列密码列表的文件，并从英语字典单词列表中检查散列单词。希望对大家有所帮助。

我从下面的链接下载了英语词典 https://github.com/dwyl/english-words

import hashlib, sys

hash_file = 'exercise\hashed.txt'
wordlist = 'data_sets\english_dictionary\words.txt'

try:
    hashdocument = open(hash_file,'r')
except IOError:
    print('Invalid file.')
    sys.exit()
else:
    count = 0
    for hash in hashdocument:
        hash = hash.rstrip('\n')
        print(hash)
        i = 0
        with open(wordlist,'r') as wordlistfile:
            for word in wordlistfile:
                m = hashlib.md5()
                word = word.rstrip('\n')            
                m.update(word.encode('utf-8'))
                word_hash = m.hexdigest()
                if word_hash==hash:
                    print('The word, hash combination is ' + word + ',' + hash)
                    count += 1
                    break
                i += 1
        print('Itiration is ' + str(i))
    if count == 0:
        print('The hash given does not correspond to any supplied word in the wordlist.')
    else:
        print('Total passwords identified is: ' + str(count))
sys.exit()
