python简单实现AES加密和解密

import base64from Crypto.Cipher import AES# 密钥（key）, 密斯偏移量（iv） CBC模式加密 def AES_Encrypt(key, data):  vi = '0102030405060708'  pad = lambda s: s + (16 - len(s)%16) * chr(16 - len(s)%16)  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 = '0102030405060708'  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)  unpad = lambda s: s[0:-s[-1]]  text_decrypted = unpad(text_decrypted)  # 去补位  text_decrypted = text_decrypted.decode('utf8')  return text_decrypted  key = '0CoJUm6Qyw8W8jud'data = 'sdadsdsdsfd'AES_Encrypt(key, data)enctext = AES_Encrypt(key, data)print(enctext)text_decrypted = AES_Decrypt(key, enctext)print(text_decrypted)
