// Creating a token
const token = jwt.sign({ name: 'John Doe', email: 'john.doe@gmail.com' }, 'secret')

// Verifing token
const isValid = jwt.verify(token, secret)

const payload = jwt.decode(token)

```

`algorithm` (optional, default: `HS256`)
The algorithm used to sign the payload, possible values: `HS256`(default) or `HS512`


### `jwt.verify(token, secret, [algorithm])`

Verifies the integrity of the token and returns a boolean value.

`token`
The token string generated by `jwt.sign()`.

`secret`
A string which is used to sign the payload.

`algorithm` (optional, default: `HS256`)
