使用更加安全的加密模式，例如CBC模式或CTR模式。

示例代码（Python实现AES CBC模式加密解密）：

import os from Crypto.Cipher import AES

class AESCipher:

def __init__(self, key):
    self.key = key

def encrypt(self, raw):
    """
    Encrypts the raw data using AES CBC mode
    :param raw: The data to encrypt
    :return: The encrypted data
    """
    raw = self._pad(raw)
    iv = os.urandom(AES.block_size)
    cipher = AES.new(self.key, AES.MODE_CBC, iv)
    return iv + cipher.encrypt(raw)

def decrypt(self, enc):
    """
    Decrypts the encrypted data using AES CBC mode
    :param enc: The encrypted data
    :return: The decrypted data
    """
    iv = enc[:AES.block_size]
    cipher = AES.new(self.key, AES.MODE_CBC, iv)
    raw = cipher.decrypt(enc[AES.block_size:])
    return self._unpad(raw).decode('utf-8')

def _pad(self, s):
    """
    Pads the given string to be a multiple of 16 bytes
    :param s: The string to pad
    :return: The padded string
    """
    return s + (AES.block_size - len(s) % AES.block_size) * chr(AES.block_size - len(s) % AES.block_size)

@staticmethod
def _unpad(s):
    """
    Removes padding from a given string
    :param s: The string to remove padding from
    :return: The unpadded string
    """
    return s[:-ord(s[len(s) - 1:])]

key = b"super_secret_key" cipher = AESCipher(key) enc = cipher.encrypt("hello world") print(enc) dec = cipher.decrypt(enc) print(dec)
