Object Storage supports secure client-server data exchange via the Transport Layer Security (TLS) protocol. To ensure robust protection of your data exchange, use TLS version 1.2 or higher.
Object Storage continues to support TLS versions 1.0 and 1.1 at the moment, but plans to deprecate them, although no issues or vulnerabilities are known.
Most of Amazon S3-compatible Object Storage clients don't let you explicitly select the TLS version, using the version specified at the system level.
To learn how to configure your clients for TLS version 1.2, see the documentation:
