Setting Bucket Encryption

Feature description

This API is used to set the default server-side encryption configuration for a bucket. To call this API, you must have the PutBucketEncryption permission. By default, the bucket owner has permission to use this API and can grant such permission to other users.

Method prototype

put_bucket_encryption(Bucket, ServerSideEncryptionConfiguration={}, **kwargs)

Sample request

# -*- coding=utf-8
from qcloud_cos import CosConfig
from qcloud_cos import CosS3Client
import sys
import os
import logging

# In most cases, set the log level to INFO. If you need to debug, you can set it to DEBUG and the SDK will print information about the communication with the server.
logging.basicConfig(level=logging.INFO, stream=sys.stdout)

# 1. Set user attributes such as secret_id, secret_key, and region. Appid has been removed from CosConfig and thus needs to be specified in Bucket, which is formatted as BucketName-Appid.
secret_id = os.environ['COS_SECRET_ID']     #  User `SecretId`. We recommend you use a sub-account key and follow the principle of least privilege to reduce risks. For information about how to obtain a sub-account key, visit https://www.tencentcloud.com/document/product/598/32675.
secret_key = os.environ['COS_SECRET_KEY']   # User `SecretKey`. We recommend you use a sub-account key and follow the principle of least privilege to reduce risks. For information about how to obtain a sub-account key, visit https://www.tencentcloud.com/document/product/598/32675.
region = 'ap-beijing'      # Replace it with the actual region, which can be viewed in the console at https://console.cloud.tencent.com/cos5/bucket.
                           # For the list of regions supported by COS, visit https://www.tencentcloud.com/document/product/436/6224.
token = None               # Token is required for temporary keys but not permanent keys. For more information about how to generate and use a temporary key, visit https://www.tencentcloud.com/document/product/436/14048.
scheme = 'https'           # Specify whether to use HTTP or HTTPS protocol to access COS. This field is optional and is `https` by default.

config = CosConfig(Region=region, SecretId=secret_id, SecretKey=secret_key, Token=token, Scheme=scheme)
client = CosS3Client(config)

config_dict = {
    'Rule': [
        {
            'ApplySideEncryptionConfiguration': {
                'SSEAlgorithm': 'AES256',
            }
        },
    ]
}
client.put_bucket_encryption(Bucket='examplebucket-1250000000', ServerSideEncryptionConfiguration=config_dict)

Querying Bucket Encryption Configuration

Feature description

This API is used to query the default server-side encryption configuration for a bucket. To call this API, you must have the GetBucketEncryption permission. By default, the bucket owner has permission to use this API and can grant such permission to other users.
