我正在尝试在win10上使用pycrypto for python 3.5.1 使用这段简单的代码:
from Crypto.Hash import SHA256
SHA256.new('abc').hexdigest()
导致此错误:
Traceback (most recent call last):
File "E:/Python/C.py", line 2, in <module>
SHA256.new('abc').hexdigest()
File "E:\Python\lib\site-packages\Crypto\Hash\SHA256.py", line 88, in new
return SHA256Hash().new(data)
File "E:\Python\lib\site-packages\Crypto\Hash\SHA256.py", line 75, in new
return SHA256Hash(data)
File "E:\Python\lib\site-packages\Crypto\Hash\SHA256.py", line 72, in __init__
HashAlgo.__init__(self, hashFactory, data)

self.update(data)
File "E:\Python\lib\site-packages\Crypto\Hash\hashalgo.py", line 69, in update
return self._hash.update(data)
TypeError: Unicode-objects must be encoded before hashing
任何人都知道问题是什么?
答案 0 :(得分:0)
使用&#39; abc&#39;上的.encode()
功能运行散列函数之前的字符串。
例如,如果您希望使用 Unicode 编码:
'abc'.encode('utf-8')
答案 1 :(得分:0)
TypeError:必须在散列之前对Unicode对象进行编码
意味着你应该这样做:
from Crypto.Hash import SHA256
print(SHA256.new('abc'.encode('utf-8')).hexdigest())
