Python Crypto module implements AES encryption instance code, cryptoaes

This article mainly explores the python Crypto module to implement AES encryption and shares the specific implementation code. The following describes the specific content.

I learned how to use the AES of the Crypto module to encrypt files. Now I can record the files for later viewing.

When I first got to know this module, it took a lot of time to install the basic Crypto module, and I didn't know what the problem was. It took a long time to install it, remember to install the package, but always prompts that Crypto cannot be found during use. cipher module. How can this problem be solved?

I. I changed my python to a 64-bit version. The computer was originally 64-bit and I don't know what it was like to install it into a 32-bit version. (O (worker _ worker) O Haha ~)
Ii. Install VCForPython27.msi
3. Run the following command in cmd:

pip install pycrypto -i http://mirrors.aliyun.com/pypi/simple/

After several steps above, I can successfully execute

from Crypto.Cipher import AES

The code of the previous instance is as follows:

# !/usr/bin/env python# coding: utf-8''''''from Crypto.Cipher import AESfrom binascii import b2a_hex, a2b_hexclass MyCrypt():  def __init__(self, key):    self.key = key    self.mode = AES.MODE_CBC  def myencrypt(self, text):    length = 16    count = len(text)    print count    if count < length:      add = length - count      text= text + ('\0' * add)    elif count > length:      add = (length -(count % length))      text= text + ('\0' * add)    # print len(text)    cryptor = AES.new(self.key, self.mode, b'0000000000000000')    self.ciphertext = cryptor.encrypt(text)    return b2a_hex(self.ciphertext)  def mydecrypt(self, text):    cryptor = AES.new(self.key, self.mode, b'0000000000000000')    plain_text = cryptor.decrypt(a2b_hex(text))    return plain_text.rstrip('\0')if __name__ == '__main__':  mycrypt = MyCrypt('abcdefghjklmnopq')  e = mycrypt.myencrypt('hello,world!')  d = mycrypt.mydecrypt(e)  print e  print d

Run the following command in cmd:
