使用AWS S3 SDK在S3和我的数据中心之间传输数据是否安全？

Question

I want to use AWS SDK to upload/download files from a private S3 bucket using Java to our data center.

I am planning to use following code

AmazonS3 s3Client = new AmazonS3Client(credentials);
s3Client.putObject(new PutObjectRequest(bucket, key, fileToUpload));
S3Object s3object = s3Client.getObject(new GetObjectRequest(bucket, key));

Will the data be traveling between S3 and our Datacenter in plain text or will it use some form of secure transport like SSL?

Answer 1

The default for communication is SSL. While HTTP is available, you would have to specifically use it. For example, from this page , you would have to do something like:

AmazonS3 s3Client = new AmazonS3Client(credentials); 
s3Client.setEndpoint("http://s3-us-west-1.amazonaws.com");

with the endpoints taken from this page .

Since you're using the defaults, your communication is via SSL/HTTPS.
