The SSE schemes described in [Secret Keys](#Secret-Keys) and [Content Encryption](#Content-Encryption) are generic over the cryptographic primitives. However, the MinIO server uses the following cryptographic primitive implementations:

- [PRF](#prf): HMAC-SHA-256
- [AEAD](#aead): AES-256-GCM if the CPU supports AES-NI, ChaCha20-Poly1305 otherwise. More specifically AES-256-GCM is only selected for X86-64 CPUs with AES-NI extension.

// produces an incorrect checksum it fails with a hard error.

	// GetObjectNInfo returns a GetObjectReader that satisfies the

	// function MUST NOT return a non-nil ReadCloser.
