Documented steps
Confirm the deployment supports the SSE mode you intend to use (SSE-S3 requires a configured KES/KMS-backed encryption setup on the server).
Set SSE-S3 as the bucket's default: mc encrypt set sse-s3 ALIAS/BUCKET. Example: mc encrypt set sse-s3 myaistor/mybucket
Verify the setting: mc encrypt info ALIAS/BUCKET (shows the current default SSE mode).
New objects written to the bucket are automatically encrypted with the configured SSE-S3 key thereafter.
Known gotchas
mc encrypt set supports ONLY SSE-KMS and SSE-S3; SSE-C (customer-provided keys) is not settable as a bucket default.
Setting/changing the default does NOT re-encrypt existing bucket contents - only affects newly written objects. To re-encrypt existing data use mc mv with --enc-s3 / --enc-kms.
If the server cannot support the specified encryption, behavior is undefined - verify server KMS/KES config first.
Requires bucket-level s3:PutEncryptionConfiguration permission. Docs: https://docs.min.io/aistor/reference/cli/ (mc encrypt set)
