python进行AES加密

from Crypto.Cipher import AES
from Crypto import Random


#补齐16字节，必须是16的倍数
def fill_text(msg):
    to_add = 0
    if len(msg) % 16 != 0:
        to_add = 16 - len(msg) % 16
        return msg + b'\0'*to_add


#AES的key必须是16、24、32位长度
key = b'12345678'
iv = Random.new().read(AES.block_size)
cipher = AES.new(fill_text(key), AES.MODE_ECB)
plaintext = '红红火火恍恍惚惚'
print('原文:', plaintext)
msg = cipher.encrypt(fill_text(plaintext.encode()))
print('加密后的字节码：', msg)

text = cipher.decrypt(msg)
print('解密后的文本：', text.decode())
