 ### HMAC Algorithms
 
-HMAC algorithms use symmetric keys, the same key can both sign and verify JWTs. This package supports HS256, HS384, and HS512 of HMAC algorithms. The example mentioned above demonstrates how to use an HMAC algorithm (HS256) to sign and verify a JWT.

 ### RSA Algorithms
 
-RSA algorithms are asymmetric. A paired key is needed to sign and verify tokens. To sign a JWT, we use a private key, and to verify it, we use the related public key. These algorithms are useful when the authentication server cannot trust resource owners. Take a look at the following example:

 ### Validation
 
-In default, the package verifies the JWT signature, validate some of the public claims if they exist (using `DefaultValidator`), and parse the claims. If you have your custom claims, you can add their validation rules, as well. See this example:

The `DefaultValidator` is a subclass of the `BaseValidator`. You can also use the `BaseValidator` for your validations, but you will lose the built-in rules, and you have to add all the rules yourself.

 #### Rules
 
-Validators use the rules to validate the claims. Each rule determines eligible values for a claim. These are the built-in rules you can find under the namespace `MiladRahimi\Jwt\Validator\Rules`:
