【py加解密】linux pyCrypto模块安装

环境：

centos 7.5+Python 2.7.5

1.下载pyCrypto安装包（https://www.dlitz.net/software/pycrypto/）

wget https://ftp.dlitz.net/pub/dlitz/crypto/pycrypto/pycrypto-2.7a1.tar.gz
wget https://ftp.dlitz.net/pub/dlitz/crypto/pycrypto/pycrypto-2.6.1.tar.gz

2.解压安装

tar zxf pycrypto-2.6.1.tar.gz

./configure

python setup.py build

　　build报错：src/MD2.c:31:20: fatal error: Python.h: No such file or directory (缺少devel包)

　　报错解决：yum install python-devel

python setup.py install

python setup.py test

　　测试可能失败，忽略

3.写一个简单demo（AES加解密）

#!/usr/bin/python
# -*- coding: utf-8 -*-

from Crypto.Cipher import AES

obj = AES.new(b'Sixteen byte key', AES.MODE_CBC, 'iv12345678901234')#密钥，模式，iv
plainMsg = "1234567890123456"
#加密
cipherMsg = obj.encrypt(plainMsg)
#print cipherMsg

obj1 = AES.new(b'Sixteen byte key', AES.MODE_CBC, 'iv12345678901234')#密钥，模式，iv
#解密
decMsg = obj1.decrypt(cipherMsg)
print decMsg
