# Verify JWT

JWT (JSON Web Token) is an open standard that defines a compact and self-contained way for securely transmitting information between parties as a JSON object. To transmit information (send and receive), **VerifyJWT** is used in conjunction with **CreateJWT**.

***

## Properties

### Token

The encoded token. (See the [CreateJWT function](/reference/plugins/overview/content/createjwt.md) for details on how to create a token.)

### Algorithm

The algorithm used to encode the token.

#### HS256, HS384, HS512

**Secret Key**

Available only when the selected Algorithm is HS256, HS384, or HS512.

The secret key as a List or Base64 to decode the payload with.

***

#### RS256, RS384, RS512

The following properties are available only when the selected Algorithm is RS256, RS384, or RS512.

**Validate using**

The type of item to validate the token with.

Options:

* Certificate
* Public key

**Certificate**

The following properties are available when the *Validate using* property is set to 'Certificate':

**Certificate file path**

The file path to load the RSA key from.

**Certificate password**

The password protecting the key file.

**Public key**

The following properties are available when the *Validate using* property is set to 'Public key':

**Modulus**

The modulus as List or Base64 used for the public key.

**Exponent**

The exponent as List or Base64 used for the public key.

***

#### ES256, ES384, ES512

Available only when the selected Algorithm is ES256, ES384, or ES512.

**Load certificate from file**

Select to load the ECDSA key from a file.

**Private key**

Available only when the *Load certificate from file* property is *not* selected.

The private key as List or Base64 to encode the payload with.

**Certificate file path**

Available only when the *Load certificate from file* property is selected.

The file path to load the ECDSA key from.

**Certificate password**

Available only when the *Load certificate from file* property is selected.

The password protecting the key file.
