     * and then creating a signature with a secret key. The token is assembled in the format:
     * `{header}.{payload}.{signature}`.
     * * @example
     * const token = authCrypto.jwt.generate({
     *      iss: 'auth.nasriya.net',
     *      exp: Math.floor(Date.now() / 1000) + 60 * 60 * 24  // 24 hours from now in seconds
     * })
     * @param payload The payload to include in the JWT. This must be an object that can be serialized to JSON.
     * @returns {string} The generated JWT token.
     * @throws {TypeError} If payload is not an object or is null.
     * @throws {Error} If the payload contains invalid or unexpected data.

     * optional message and the decoded payload if valid.

     * @param token - The JWT token to verify. It must be in the format: `JWT.{header}.{payload}.{signature}`.

     * of the verification:
     * - `valid` (boolean): `true` if the token is valid, `false` otherwise.
     * - `payload` (optional): The decoded payload if the token is valid.
     * - `message` (optional): A description of why the token is invalid, if applicable.
