## Adicione headers customizados

Há certas situações em que é bastante útil poder adicionar headers customizados no HTTP error. Exemplo disso seria adicionar headers customizados para tipos de segurança.

Você provavelmente não precisará utilizar esses headers diretamente no seu código.

Mas caso você precise, para um cenário mais complexo, você pode adicionar headers customizados:

```Python hl_lines="14"

			if crypto.SSEC.IsRequested(headers) || crypto.SSECopy.IsRequested(headers) {
				return encrypted, errEncryptedObject
			}
		}

		if crypto.S3KMS.IsEncrypted(info.UserDefined) && r.Header.Get(xhttp.AmzCopySource) == "" {
			if crypto.SSEC.IsRequested(headers) || crypto.SSECopy.IsRequested(headers) {
				return encrypted, errEncryptedObject
			}
		}

	"X-Minio-Replication-Encrypted-Multipart",
	"X-Minio-Replication-Actual-Object-Size",
	ReplicationSsecChecksumHeader,
	// Add more supported headers here.
}

// mapping of internal headers to allowed replication headers
var validSSEReplicationHeaders = map[string]string{
	"X-Minio-Internal-Server-Side-Encryption-Sealed-Key":     "X-Minio-Replication-Server-Side-Encryption-Sealed-Key",

    signatureVersion: 'v4'
});

// List all contents stored in the zip archive
s3.listObjectsV2({Bucket : 'your-bucket', Prefix: 'path/to/file.zip/'}).
    on('build', function(req) { req.httpRequest.headers['X-Minio-Extract'] = 'true'; }).
    send(function(err, data) {
        if (err) {
            console.log("Error", err);
        } else {
            console.log("Success", data);
        }
    });

	_ Type = SSEC
)

// String returns the SSE domain as string. For SSE-C the
// domain is "SSE-C".
func (ssec) String() string { return "SSE-C" }

// IsRequested returns true if the HTTP headers contains
// at least one SSE-C header. SSE-C copy headers are ignored.
func (ssec) IsRequested(h http.Header) bool {
	if _, ok := h[xhttp.AmzServerSideEncryptionCustomerAlgorithm]; ok {
		return true
	}
