Question

How do you set up server-side encryption for an S3 bucket?

Answer 1

You can configure server-side encryption (SSE) using Boto3. 

Here’s an example:

import boto3

s3 = boto3.client('s3')

bucket_name = 'my-bucket-name'

# Set up server-side encryption
encryption_configuration = {
    'Rules': [
        {
            'ApplyServerSideEncryptionByDefault': {
                'SSEAlgorithm': 'AES256'
            }
        }
    ]
}

s3.put_bucket_encryption(
    Bucket=bucket_name,
    ServerSideEncryptionConfiguration=encryption_configuration
)

This script sets up SSE with AES-256 encryption for the bucket.
