Documented steps

  1. Ensure the deployment is configured for SSE-KMS with the target key present (root encrypted with key minio-encryption-key in the example).
  2. Set SSE-KMS with an explicit key: mc encrypt set sse-kms KMSKEY ALIAS/BUCKET. Example: mc encrypt set sse-kms minio-encryption-key myaistor/mydata
  3. To use the server's default key instead, omit KMSKEY: mc encrypt set sse-kms ALIAS/BUCKET (falls back to MINIO_KMS_KES_KEY_NAME).
  4. Confirm with mc encrypt info ALIAS/BUCKET.
