AES和DES使用python实现

AES加解密

import base64
如果没有这个模块，建议使用pycryptodomex
from Crypto.Cipher import AES

密钥（key）, 偏移量（vi） CBC模式加密
def AES_Encrypt(key, data):
    vi = 'Cooooooooooooool'
    pad = lambda s: s + (16 - len(s)%16) * chr(0)
    data = pad(data)
    # 字符串补位
    cipher = AES.new(key.encode('utf8'), AES.MODE_CBC, vi.encode('utf8'))
    encryptedbytes = cipher.encrypt(data.encode('utf8'))
    # 加密后得到的是bytes类型的数据
    encodestrs = base64.b64encode(encryptedbytes)
    # 使用Base64进行编码,返回byte字符串
    enctext = encodestrs.decode('utf8')
    # 对byte字符串按utf-8进行解码
    return enctext
 
def AES_Decrypt(key, data):
    vi = 'Cooooooooooooool'
    data = data.encode('utf8')
    encodebytes = base64.decodebytes(data)
    # 将加密数据转换位bytes类型数据
    cipher = AES.new(key.encode('utf8'), AES.MODE_CBC, vi.encode('utf8'))
    text_decrypted = cipher.decrypt(encodebytes)
    text_decrypted=text_decrypted.rstrip(b'\0')  
    # 去补位
    text_decrypted = text_decrypted.decode('utf8')
    return text_decrypted

测试
key = 'Cooooooooooooool'
data = '{"hahahha":"","youyouyou":"","ninini":"uuu"}'
AES_Encrypt(key, data)
enctext = AES_Encrypt(key, data)
print(enctext)
AES_Decrypt(key, enctext)
text_decrypted = AES_Decrypt(key, enctext)
print(text_decrypted)
`

DES加密
`
import base64
import random
import time
from pyDes import des, ECB

def pad(b):
    """
    块填充
    """
    block_size = 8
    while len(b) % block_size:
        b += b'\0'
    return b

def get_encrypt_content(message, key, flag):
    """
    接口参数的加密、解密
    """
    des_obj = des(key.encode(), mode=ECB)
    if flag:
        content = pad(str(message).replace(' ', '').encode())
        return base64.b64encode(des_obj.encrypt(content)).decode('utf-8')
    else:
        return des_obj.decrypt(base64.b64decode(message)).decode('utf-8')
