Question

我尝试用python加密文本然后执行我的代码我得到一个错误：

import base64

import boto3
from Crypto.Cipher import AES


PAD = lambda s: s + (32 - len(s) % 32) * ' '


def get_arn(aws_data):
    return 'arn:aws:kms:{region}:{account_number}:key/{key_id}'.format(**aws_data)


def encrypt_data(aws_data, plaintext_message):
    kms_client = boto3.client(
        'kms',
        region_name=aws_data['region'])

    data_key = kms_client.generate_data_key(
        KeyId=aws_data['key_id'],
        KeySpec='AES_256')

    cipher_text_blob = data_key.get('CiphertextBlob')
    plaintext_key = data_key.get('Plaintext')

    # Note, does not use IV or specify mode... for demo purposes only.
    cypher = AES.new(plaintext_key, AES.MODE_ECB)
    encrypted_data = base64.b64encode(cypher.encrypt(PAD(plaintext_message)))

    # Need to preserve both of these data elements
    return encrypted_data, cipher_text_blob



def main():
    # Add your account number / region / KMS Key ID here.
    aws_data = {
        'region': 'eu-west-1',
        'account_number': '701177775058',
        'key_id': 'd67e033d-83ac-4b5e-93d4-aa6cdc3e292e',
    }

    # And your super secret message to envelope encrypt...
    plaintext = PAD('Hello, World!')

    # Store encrypted_data & cipher_text_blob in your persistent storage. You will need them both later.
    encrypted_data, cipher_text_blob = encrypt_data(aws_data, plaintext)
    print(encrypted_data)


if __name__ == '__main__':
    main()

我得到：提出TypeError（“只有字节字符串可以传递给C代码”） TypeError：只能将字节字符串传递给C代码也许谁知道为什么？我该如何解决？请建议！

Answer 1

在这里写@Jeronimo的评论作为答案，我也遇到了同样的问题而且这有帮助。

将.encode("utf-8")附加到您传递给cypher.encrypt()函数的任何内容。

cypher.encrypt(PAD(plaintext_message).encode("utf-8"))

注意：这似乎是针对python 3.x.对于2.x，这个相同的解决方案可能无效。

使用AES加密获取引发TypeError（“只有字节字符串可以传递给C代码”）
