*  非对称加密RSA在项目中比较常用，需要公钥和私钥，这里就进行一对钥匙的生成

# RSA公钥私钥生成 #

*  载入拓展包

> composer require phpseclib/phpseclib

*  项目引入

<?php
    require __DIR__ . '/vendor/autoload.php';
    use phpseclib\Crypt\RSA;
    $rsa = new RSA();
    extract($rsa->createKey()); 
    echo $privatekey;
    echo $publickey;

*  F12打开浏览器的控制台的`Network`的`Response`，就能看到我们所需要的，复制进行保存

 *  私钥

*  公钥

# RAS验证 #

*  这里我们利用jwt进行验证

> composer require firebase/php-jwt

<?php
    use \Firebase\JWT\JWT;

*  在jwt中能够正常的加密解密证明我们RSA密匙已经正确的生成了
