使用AES对压缩文件里的文件加密的python代码

以下是一个使用AES对压缩文件里的文件加密的Python代码示例：

import os
import zipfile
from Crypto.Cipher import AES

def encrypt_file(key, in_filename, out_filename=None, chunksize=64*1024):
    if not out_filename:
        out_filename = in_filename + '.enc'

    iv = os.urandom(16)
    encryptor = AES.new(key, AES.MODE_CBC, iv)

    with open(in_filename, 'rb') as infile:
        with open(out_filename, 'wb') as outfile:
            outfile.write(iv)

            while True:
                chunk = infile.read(chunksize)
                if len(chunk) == 0:
                    break
                elif len(chunk) % 16 != 0:
                    chunk += b' ' * (16 - len(chunk) % 16)

                outfile.write(encryptor.encrypt(chunk))

def encrypt_zipfile(key, in_filename, out_filename=None, chunksize=64*1024):
    if not out_filename:
        out_filename = in_filename + '.enc'

    iv = os.urandom(16)
    encryptor = AES.new(key, AES.MODE_CBC, iv)

    with zipfile.ZipFile(in_filename, 'r') as inzip:
        with zipfile.ZipFile(out_filename, 'w') as outzip:
            for filename in inzip.namelist():
                with inzip.open(filename, 'r') as infile:
                    with outzip.open(filename, 'w') as outfile:
                        outfile.write(iv)

                        while True:
                            chunk = infile.read(chunksize)
                            if len(chunk) == 0:
                                break
                            elif len(chunk) % 16 != 0:
                                chunk += b' ' * (16 - len(chunk) % 16)

                            outfile.write(encryptor.encrypt(chunk))

# Example usage
key = b'mysecretkey12345'
encrypt_file(key, 'mydata.txt', 'mydata.txt.enc')
encrypt_zipfile(key, 'mydata.zip', 'mydata.zip.enc')

该代码使用了PyCrypto库中的AES模块进行加密，同时使用了Python内置的zipfile模块来处理压缩文件。加密过程中，每个文件都会使用一个随机的初始化向量（IV）来增加安全性。加密后的文件会在原文件名后加上“.enc”后缀。注意，这里只是对文件进行了加密，如果需要对整个压缩文件进行加密，则需要先解压缩文件，然后对每个文件进行加密，最后再进行压缩。
