python——rsa和aes加解密 _PyThon

案头见蠹鱼，犹胜凡俦侣。这篇文章主要讲述python——rsa和aes加解密相关的知识，希望能为你提供帮助。
python操作rsa和aes加解密
封装了一个python的操作rsa和aes的加解密类
首先pip装库
pip install pycrypto
由于pycrypto多年未更新维护，也可以安装 PyCryptodome
【python——rsa和aes加解密】代码：
-- coding:utf-8 --import base64
from Crypto import Random
from Crypto.Hash import SHA
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
from Crypto.Cipher import AES
from binascii import b2a_hex, a2b_hex
#AES加解密,用于本地加密数据库密码和rsa private key
aes_salt = " opquweoijuqowieh"
class Aes():

def __init__(self, key=aes_salt): self.key = key self.mode = AES.MODE_CBCdef encrypt(self, text): cryptor = AES.new(self.key, self.mode, b\'0000000000000000\') length = 16 count = len(text) if count < length: add = (length-count) text = text + (\'\\0\' * add) elif count > length: add = (length-(count % length)) text = text + (\'\\0\' * add) self.ciphertext = cryptor.encrypt(text) return b2a_hex(self.ciphertext)def decrypt(self, text): cryptor = AES.new(self.key, self.mode, b\'0000000000000000\') plain_text = cryptor.decrypt(a2b_hex(text)) return plain_text.rstrip(\'\\0\')

#rsa加解密,用于cookie的加解密
class Rsa():

def __init__(self): self.random_generator = Random.new().readdef gen_rsa_keys(self): rsa = RSA.generate(1024, self.random_generator) private_pem = rsa.exportKey() public_pem = rsa.publickey().exportKey() return (private_pem, public_pem)def crypto(self, public_key, text): rsakey = RSA.importKey(public_key) cipher = Cipher_pkcs1_v1_5.new(rsakey) crypto_text = base64.b64encode(cipher.encrypt(text)) return crypto_textdef decrypt(self, private_key, text): rsakey = RSA.importKey(private_key) cipher = Cipher_pkcs1_v1_5.new(rsakey) decrypt_text = cipher.decrypt(base64.b64decode( text), self.random_generator) return decrypt_text

if name == \'main\':
rsa = Rsa()
aes = Aes()
(pri,pub)=rsa.gen_rsa_keys()
jm = rsa.crypto(pub, " fsagjdak***1343129" )
print rsa.decrypt(pri, jm)
