Encrypted the file from S3 side. Need to decrypt the file from EFS side

Question

Hi I have a file that upload on AWS S3 bucket where we enable KMS encryption . With AWS Datasync we will be transfering my file from s3 to EFS. How we can decrypt the file.

Answer 1

You do not have to do anything. AWS will decrypt the S3 file automatically whenever you read it if you are using encryption at rest.
