AWS Signature Version 4 With Wasabi

AWS Signature Version 4 allows you to authenticate your requests to AWS resources. Signature Version 4 can be used with Wasabi by pointing the "Host:" header to Wasabi servers. The Signature generation process is explained in detail Amazon S3 API Reference. Below are the instructions to get Signature version 4 working with Wasabi using Java language:

1. AWS provides a signature calculation example. Download the jar file.

2. Import the jar files to a project in any one of the Java IDEs such as Eclipse, NetBeans, IntelliJ, and so on.

3. The above jar file has examples to upload a file to a bucket, retrieve a file from a bucket, generate a pre-signed URL, and to perform a chunked upload

4. Type in the Wasabi Access Keys, bucket name, and the region name in the "RunAllSamples.java" file:

   

5. Replace s3.amazonaws.com with s3.wasabisys.com" for the endpointURL variable in the following files:

   PutS3ObjectSample.java, GetS3ObjectSample.java, PresignedUrlSample.java, PutS3ObjectChunkedSample.java.

   

6. Save all the files and run the RunAllSamples.java file

   Note that this example uses Wasabi’s us-east-1 storage region. To use other Wasabi storage regions, use the appropriate Wasabi service URL as described in Service URLs for Wasabi’s Storage Regions.
