python_rsa加密解密

使用python进行rsa加密与加密,包括公钥加密私钥解密,私钥加密公钥解密。(需要安装M2Crypto库)。

#!/usr/bin/env python
#encoding=utf-8

from M2Crypto import RSA 
msg = 'aaaa-aaaa'
rsa_pub = RSA.load_pub_key('rsa_pub.pem')
rsa_pri = RSA.load_key('rsa_pri.pem')
print '*************************************************************'
print '公钥加密,私钥解密'
ctxt = rsa_pub.public_encrypt(msg, RSA.pkcs1_padding)
ctxt64 = ctxt.encode('base64')
print ('密文:%s'% ctxt64)
rsa_pri = RSA.load_key('rsa_pri.pem')
txt = rsa_pri.private_decrypt(ctxt, RSA.pkcs1_padding)
print('明文:%s'% txt)
print '*************************************************************'
print '私钥加密,公钥解密'
ctxt_pri = rsa_pri.private_encrypt(msg, RSA.pkcs1_padding)
ctxt64_pri = ctxt.encode('base64')
print ('密文:%s'% ctxt64_pri)
txt_pri = rsa_pub.public_decrypt(ctxt_pri, RSA.pkcs1_padding)
print('明文:%s'% txt_pri)
