Hello, On gitgub they tell us: Support AWS Signature Version 2 (Version 4 is not ready) But in changelog they tell that they support v4: Amazon S3 Signature V4 support I tried to use aws java s3 client and mino java client to send requests to swift but without success. Both show either 403 or 400 error.. When I use command line tool (s3curl.pl) it works. Does Swift3 support v4? What can be wrong?
