   to use a memory-hard function (Argon2) that (on purpose) consumes a lot of memory and CPU.
   The new KMS-based approach can use a key derivation function that is orders of magnitudes
   cheaper w.r.t. memory and CPU.
- Root credentials can now be changed easily. Before, a two-step process was required to
   change the cluster root credentials since they were used to en/decrypt the IAM data.

	// Get credential.
	credentials := globalActiveCred
	if !globalReplicationPool.IsSet() {
		globalReplicationPool.Set(nil)
	}
	testServer.Obj = objLayer
	testServer.rawDiskPaths = disks
	testServer.Disks = mustGetPoolEndpoints(0, disks...)
	testServer.AccessKey = credentials.AccessKey
	testServer.SecretKey = credentials.SecretKey

/home/user1/.minio
└─ certs
   ├─ CAs
   ├─ private.key
   └─ public.crt
```

You can provide a custom certs directory using `--certs-dir` command line option.

#### Credentials

On MinIO admin credentials or root credentials are only allowed to be changed using ENVs namely `MINIO_ROOT_USER` and `MINIO_ROOT_PASSWORD`.

```sh
export MINIO_ROOT_USER=minio
export MINIO_ROOT_PASSWORD=minio13
minio server /data
```

			if u.Credentials.IsTemp() {
				// We should delete such that the client can re-request
				// for the expiring credentials.
				deleteKeyEtcd(ctx, ies.client, getUserIdentityPath(user, userType))
				deleteKeyEtcd(ctx, ies.client, getMappedPolicyPath(user, userType, false))
			}
			return nil
		}
		u.Credentials.Claims = jwtClaims.Map()
	}
	if u.Credentials.Description == "" {

Use `Response.challenges()` to get the schemes and realms of any authentication challenges. When fulfilling a `Basic` challenge, use `Credentials.basic(username, password)` to encode the request header.

        System.arraycopy(clientChallenge, 0, response, 16, 8);
        return response;
    }

    /**
     * Generate the Unicode MD4 hash for the password associated with these credentials.
     *
     * @param password the password to hash
     * @param challenge the server challenge bytes
     * @return the calculated response
     * @throws GeneralSecurityException if a cryptographic error occurs

**Note**: On distributed systems, root credentials are recommend to be defined by exporting the `MINIO_ROOT_USER` and  `MINIO_ROOT_PASSWORD` environment variables. If no value is set MinIO setup will assume `minioadmin/minioadmin` as default credentials. If a domain is required, it must be specified by defining and exporting the `MINIO_DOMAIN` environment variable.
