# KMS IAM/Config Encryption

MinIO supports encrypting config, IAM assets with KMS provided keys. If the KMS is not enabled, MinIO will store the config, IAM data as plain text erasure coded in its backend.

## MinIO KMS Quick Start

MinIO supports two ways of encrypting IAM and configuration data.
You can either use KES - together with an external KMS - or, much simpler,

package kms

// Top level config constants for KMS
const (
	EnvKMSSecretKey        = "MINIO_KMS_SECRET_KEY"
	EnvKMSSecretKeyFile    = "MINIO_KMS_SECRET_KEY_FILE"
	EnvKESEndpoint         = "MINIO_KMS_KES_ENDPOINT"       // One or multiple KES endpoints, separated by ','

// and checks whether they are well-formed. It returns the sealed object key
// on success. If the metadata contains both, a KMS master key ID and a sealed
// KMS data key it returns both. If the metadata does not contain neither a
// KMS master key ID nor a sealed KMS data key it returns an empty keyID and
// KMS data key. Otherwise, it returns an error.
