python实现AES和RSA加解密的方法

from Crypto import Random
from Crypto.Hash import SHA
from Crypto.Cipher import AES
from Crypto.Cipher import PKCS1_v1_5 as Cipher_pkcs1_v1_5
from Crypto.Signature import PKCS1_v1_5 as Signature_pkcs1_v1_5
from Crypto.PublicKey import RSA
import base64


# 秘钥
key = 'chenqichenqi1234'

# 明文
raw = 'sina company11111111111111111111'

# 加密
iv = Random.new().read(AES.block_size)
cipher = AES.new(key, AES.MODE_CFB, iv)
data = iv + cipher.encrypt(raw)


# 解密
iv = data[:16]
cipher = AES.new(key, AES.MODE_CFB, iv)
print cipher.decrypt(data[16:])

# 伪随机数生成器
random_generator = Random.new().read

# rsa算法生成实例
rsa = RSA.generate(1024, random_generator)

# 秘钥对的生成
private_pem = rsa.exportKey()
public_pem = rsa.publickey().exportKey()
message = "chenqi"

# 公钥加密
rsakey = RSA.importKey(public_pem)
cipher = Cipher_pkcs1_v1_5.new(rsakey)
cipher_text = base64.b64encode(cipher.encrypt(message))
print cipher_text


# 私钥解密
rsakey = RSA.importKey(private_pem)
cipher = Cipher_pkcs1_v1_5.new(rsakey)
text = cipher.decrypt(base64.b64decode(cipher_text), random_generator)
print text
