Python3的AES加密和解密

此加密和解密的秘钥的长度必须是16位、24位或者32位

import base64
import os
from Crypto.Cipher import AES

# AES key must be either 16, 24, or 32 bytes long
aes_key = "12345678901234567890123456789012"

# 加密
def aes_encrypt(data): 
    key=aes_key  #加密时使用的key，只能是长度16,24和32的字符串
    BS = AES.block_size
    pad = lambda s: s + (BS - len(s) % BS) * chr(BS - len(s) % BS)
    cipher = AES.new(key)
    encrypted = cipher.encrypt(pad(data))  #aes加密
    result = base64.b64encode(encrypted)  #base64 encode
    return result  

# 解密
def aes_decrypt(data):
    key=aes_key 
    unpad = lambda s : s[0:-s[-1]]
    cipher = AES.new(key)
    result2 = base64.b64decode(data)
    decrypted = unpad(cipher.decrypt(result2))
    return  decrypted

encrypted_text = aes_encrypt("{'token':'123456', 'name':'Victor','age':1, 'gender':1, 'id':123, 'company':'injiajia.com'}")
print("加密输出：")
print(encrypted_text)

decrypted_text = aes_decrypt(encrypted_text)
print("解密输出：")
print(decrypted_text)
