AWS Signature V4 for new S3 regions supported
3 years ago, Amazon Web Service announced in their forum a new signature algorithm called AWS Signature Version 4 for even more security. Existing regions are still compatible with V2, whereas the new ones launched after January 30, 2014 only support V4 like the Frankfurt and Beijing regions.
So today, we added support for AWS Signature V4 which is now the default algorithm used by the Coconut platform. There is nothing to do on your side when providing the S3
output_url, we automatically retrieve the bucket location which is an essential part in the signature Version 4.
