RSA加密一般使用RSA/ECB/PKCS1Padding(算法/工作模式/填充方式)，AES加密一般使用AES/ECB/PKCS5Padding。但python中的补码需要自己进行填充。
生产RSA的公钥和私钥
代码语言：javascript复制# -*- coding: utf-8 -*-
import rsa
# 先生成一对密钥，然后保存.pem格式文件，当然也可以直接使用
(pubkey, privkey) = rsa.newkeys(1024)
pub = pubkey.save_pkcs1()
pubfile = open('public.pem','w ')
pubfile.write(pub)
pubfile.close()
pri = privkey.save_pkcs1()
prifile = open('privateKey.pem','w ')
prifile.write(pri)
prifile.close()RSA加解密
代码语言：javascript复制# rsa加密
def rsa_encrypt(message):
with open('pubkey.pem') as f:
key = f.read()
rsakey = RSA.importKey(key)
cipher = Cipher_pkcs1_v1_5.new(rsakey)
cipher_text = base64.b64encode(cipher.encrypt(message))
return cipher_text
# rsa解密
def rsa_decrypt(message):
with open('privateKey.pem') as f:
key = f.read()
rsakey = RSA.importKey(key)
cipher = Cipher_pkcs1_v1_5.new(rsakey)
message = message.encode("ascii")
byte_msg = base64.b64decode(message)
random_generator = Random.new().read
return cipher.decrypt(byte_msg, random_generator)AES加密
代码语言：javascript复制BLOCK_SIZE = 16 # Bytes
# 填充补码，不足16*N个字节，填充字符为chr(填充个数)
pad = lambda s: s (BLOCK_SIZE - len(s) % BLOCK_SIZE) *
chr(BLOCK_SIZE - len(s) % BLOCK_SIZE)
# 去掉填充的补码
unpad = lambda s: s[:-ord(s[len(s) - 1:])]
def aes_encrpty(key, message):
message = pad(message)
cipher = AES.new(key, AES.MODE_ECB)
aessource = cipher.encrypt(message)
return base64.b64encode(aessource)
def aes_decrpty(key, message):
cipher = AES.new(key, AES.MODE_ECB)
aessource = cipher.decrypt(base64.b64decode(message))
return unpad(aessource).decode('utf8')文章到这里就全部讲述完啦，若有其他需要交流的可以留言哦！！
