openssl不是由pycrypto加密的解密文件

我在python中加密文件:

from Crypto.Cipher import AES
from Crypto import Random
key = Random.new().read(16)
iv = Random.new().read(AES.block_size)
encryptor = AES.new(key, AES.MODE_CBC, iv)
with open(in_file, 'rb') as fin, open(out_file, 'wb') as fout:
    fout.write(iv)
    while True:
        chunk = fin.read(16*1024)
        if len(chunk) == 0:
             break
        elif len(chunk) % 16 != 0:
             chunk += b' ' * (16 - len(chunk) % 16)
        fout.write(encryptor.encrypt(chunk)
print base64.b32encode(key)

但是当我尝试用openssl解密它之后: openssl aes-256-cbc -d -in enc -out new.zip 它返回魔术袋号码 我做错了什么?

答案 0 :(得分:0)

程序使用128位AES密钥进行加密,如下所示:

key = Random.new().read(16)

所以,而不是使用

openssl aes-256-cbc -d -in enc -out new.zip

使用此

openssl aes-128-cbc -d -in enc -out new.zip
