This code is something you can actually use in your application, save the password hashes in your database, etc.

We are going to start from where we left in the previous chapter and increment it.

## About JWT { #about-jwt }

JWT means "JSON Web Tokens".

It's a standard to codify a JSON object in a long dense string without spaces. It looks like this:

```

	pathutil "path"
	"strings"
	"sync"
	"time"

	"github.com/minio/minio/internal/grid"
	xioutil "github.com/minio/minio/internal/ioutil"
)

func renameAllBucketMetacache(epPath string) error {
	// Rename all previous `.minio.sys/buckets/<bucketname>/.metacache` to
	// to `.minio.sys/tmp/` for deletion.
	return readDirFn(pathJoin(epPath, minioMetaBucket, bucketMetaPrefix), func(name string, typ os.FileMode) error {
		if typ == os.ModeDir {

        Smb2SessionSetupRequest request = new Smb2SessionSetupRequest(context, 0x03, // SMB2_NEGOTIATE_SIGNING_ENABLED | SMB2_NEGOTIATE_SIGNING_REQUIRED
                0, // Capabilities
                0L, // Previous session ID (0 for binding)
                bindingHash // Security buffer contains the binding information
        );

        // Set the session ID of the existing session
        request.setSessionId(getSessionId());

	// value captured in current cycle
	Current float64

	// Used when system provides cumulative (since uptime) values
	// helps in calculating the current value by comparing the new
	// cumulative value with previous one
	Cumulative float64

	Max   float64
	Avg   float64
	Sum   float64
	Count uint64
}

func init() {
	interval := fmt.Sprintf("%ds", int(resourceMetricsCollectionInterval.Seconds()))

This could be especially useful during testing, as it's very easy to override a dependency with your own custom settings.

### The config file { #the-config-file }

Coming from the previous example, your `config.py` file could look like:

{* ../../docs_src/settings/app02/config.py hl[10] *}

Notice that now we don't create a default instance `settings = Settings()`.
