MinIO supports two different types of server-side encryption ([SSE](#sse)):

- **SSE-C**: The MinIO server en/decrypts an object with a secret key provided by the S3 client as part of the HTTP request headers. Therefore, [SSE-C](#ssec) requires TLS/HTTPS.
- **SSE-S3**: The MinIO server en/decrypts an object with a secret key managed by a KMS. Therefore, MinIO requires a valid KMS configuration for [SSE-S3](#sses3).
