Я попытался сделать демо-версию с использованием python 3.6 и boto3 с AWS KMS, но в нем отсутствует режим работы AES.Интересно, вы можете указать мне, как это сделать?Вот код:
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'],
aws_access_key_id='your_key_id',
aws_secret_access_key='your_secred_key_id')
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_CBC)
encrypted_data = base64.b64encode(cypher.encrypt(PAD(plaintext_message)))
# Need to preserve both of these data elements
return encrypted_data, cipher_text_blob
def decrypt_data(aws_data, encrypted_data, cipher_text_blob):
kms_client = boto3.client(
'kms',
region_name=aws_data['region'])
decrypted_key = kms_client.decrypt(CiphertextBlob=cipher_text_blob).get('Plaintext')
cypher = AES.new(decrypted_key)
return cypher.decrypt(base64.b64decode(encrypted_data)).rstrip()
def main():
# Add your account number / region / KMS Key ID here.
aws_data = {
'region': 'us-east-1',
'account_number': 'your_account',
'key_id': 'your_key_id',
}
# And your super secret message to envelope encrypt...
plaintext = 'Superduper and the mighty Scoop!'
# 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)
# # Later on when you need to decrypt, get these from your persistent storage.
decrypted_data = decrypt_data(aws_data, encrypted_data, cipher_text_blob)
print(decrypted_data)
if __name__ == '__main__':
main()
