Question

所以我需要对唯一用户进行身份验证，因此每个用户都有自己的priv / pub密钥对。我试图创建一个可以生成密钥对的轻量级类，然后加密或解密数据。

这是我到目前为止所做的：

class RSA
{
    public $pubkey = '';
    public $privkey = '';

    public function genKeys()
    {
        /* Create the private and public key */
        $res = openssl_pkey_new();

        /* Extract the private key from $res to $privKey */
        openssl_pkey_export($res, $privKey);
        $this->privkey = $privKey;

        /* Extract the public key from $res to $pubKey */
        $pubKey = openssl_pkey_get_details($res);
        $pubKey = $pubKey["key"];

        $this->pubkey = $pubKey;
    }

    public function encrypt($data)
    {
        $data = '';
        if (openssl_private_encrypt($data, $encrypted, $this->privkey))
            $data = base64_encode($encrypted);
        return $data;
    }

    public function decrypt($data)
    {
        $data = '';
        if (openssl_public_decrypt(base64_decode($data), $decrypted, $this->pubkey))
            $data = $decrypted;
        return $data;
    }
}

我正在加密数据，然后解密和回显纯文本，但它总是返回空白？

$RSA = new RSA();
$RSA->genKeys();

$text = "Hello World.";

$e = $RSA->encrypt($text);
$m = $RSA->decrypt($e);

echo "Encrypted: $e <br />";
echo "Decrypted: $m <br />";

有什么想法吗？而且我不想使用繁重的库。尽可能轻量级是完美的。

我删除了基本编码并让它工作：

class RSA
{
    public $privKey = '';
    public $pubKey = '';

    public function genKeys()
    {
        $res = openssl_pkey_new();

        // Get private key
        openssl_pkey_export($res, $priv);
        $this->privKey = $priv;

        // Get public key
        $pubkey = openssl_pkey_get_details($res);
        $this->pubKey = $pubkey["key"];
    }

    public function private_encrypt( $tocrypt )
    {
        $output = "";
        openssl_private_encrypt($tocrypt, $output, $this->privKey);
        return $output;
    }

    public function public_decrypt( $tocrypt )
    {
        $output = "";
        openssl_public_decrypt($tocrypt, $output, $this->pubKey);
        return $output;
    }
}

$RSA = new RSA();
$RSA->genKeys();

$m = "hi";

$e = $RSA->private_encrypt( $m );

echo $RSA->public_decrypt( $e );
