Description
There is a issue with + in object key name which leads to SignatureDoesNotMatch.
Based on my debug I think that the issue comes from the fact that function aws4_uri_recode is run before the + for %20 replacement as you can see here.
https://github.com/ceph/ceph/blob/main/src/rgw/rgw_auth_s3.h#L521
This means that the + will be recoded to %2b so the replace afterwards will not be applied -> SignatureDoesNotMatch
Because of this there is a AWS s3 and Ceph difference because on s3 the + will be recoded as %20
