#### Rationale

- SSE-C requires application to remember the keys for all GET/PUT operations, any unfortunate loss of keys would automatically mean the objects cannot be accessed anymore.
- SSE-C is hardly adopted by most widely used applications, applications prefer server to manage the keys via SSE-KMS or SSE-S3.
- MinIO recommends applications to use SSE-KMS, SSE-S3 for simpler, safer and robust encryption mechanism for replicated buckets.
