Editor’s Assessment

Amazon S3 has become a widely used and reliable platform for storing large datasets, however, when transferring particularly large datasets there is a risk that changes to the original data can occur during transmission. To address this the authors have developed aws-s3-integrity-check, a user-friendly, lightweight and reliable bash tool to verify the integrity of a dataset stored within an Amazon S3 bucket. The testing and review process fixed a few bugs, and limitations on multipart datasets are now clearly presented. So based on this the work provides a useful open-source option to allow verifying the integrity of uploaded datasets.
