使用私钥在python中简单加密/解密lib [英] simple encrypt/decrypt lib in python with private key

问题描述

有没有一种简单的方法可以用密钥对字符串进行加密/解密?

Is there a simple way to encrypt/decrypt a string with a key?

类似的东西:

key = '1234'
string =  'hello world'
encrypted_string = encrypt(key, string)
decrypt(key, encrypted_string)

我找不到任何简单的方法.

I couldn't find anything simple to do that.

来自他们的文档页面.

>>> from Crypto.Cipher import DES
>>> obj=DES.new('abcdefgh', DES.MODE_ECB)
>>> plain="Guido van Rossum is a space alien."
>>> len(plain)
34
>>> obj.encrypt(plain)
Traceback (innermost last):
  File "<stdin>", line 1, in ?
ValueError: Strings for DES must be a multiple of 8 in length
>>> ciph=obj.encrypt(plain+'XXXXXX')
>>> ciph
'\021,\343Nq\214DY\337T\342pA\372\255\311s\210\363,\300j\330\250\312\347\342I\3215w\03561\303dgb/\006'
>>> obj.decrypt(ciph)
'Guido van Rossum is a space alien.XXXXXX'
