[ceph-users] Multisite sync: is metadata transferred in plain text?

Hi, We have a multisite Ceph configuration, with http (not https) sync endpoints. Are all sync traffic in plain text? We have concerns about metadata. For example, when syncing a newly created user and its access key and secret key from the Master zone to a secondary zone, is this traffic in plain text? If so, what are options to encrypt it? Thank you, Mary
