"Class name must be a valid object or a string" 在没有 Composer 的情况下安装 PHPSecLib
"Class name must be a valid object or a string" When Installing PHPSecLib Without Composer
我正在尝试使用 PHPSecLib 通过手动安装（即不使用 Composer）进行 RSA 加密。
我正在按照我在此处找到的这些手动安装说明进行操作：
https://davescripts.com/manual-installation-of-phpseclib
并尝试执行我位于此处的示例：
到目前为止我的步数：
在此处访问了 GitHub 存储库：https://github.com/phpseclib/phpseclib/tree/3.0
在 'Code' 下选择了 'Download ZIP'。
在本地解压缩文件并将整个 'phpseclib' 目录上传到服务器。
创建了一个测试脚本，并解决了使其工作所需的多层包含和使用问题。
但是，目前，我收到一个新错误 - “Class 名称必须是一个有效的对象或字符串”，我不明白也不能似乎解决了。
我现在的测试脚本如下：

如果有帮助，请注意测试脚本位于单独的目录中，如下所示：
inc
-> phpseclib (the PHPSecLib library with all subdirectories)
main
-> phpseclibtest.php (my test script)
PHP 版本是 7.0.33，如果这有什么不同的话。
我真的很想知道如何让 PHPSecLib 工作。如果有人能帮我弄清楚发生了什么，那就太好了。
您正在尝试使用 phpseclib v2 的说明安装 phpseclib v3。有两种选择：
选项 1：将 PHPSecLib V3 与 Composer 一起使用
此选项需要在服务器上进行 SSH 访问。
要安装 phpseclib v3，您需要 Composer。安装完成后，您可以执行 composer init 然后 composer require phpseclib/phpseclib:~3.0.
通过这样做你可以替换这个：
ini_set('display_errors', 1); ini_set('display_startup_errors', 1); error_reporting(E_ALL);
header("Content-Type: text/plain");
$sIncludePath = get_include_path() . PATH_SEPARATOR . '../inc/phpseclib';
echo $sIncludePath."\n";
set_include_path($sIncludePath);
include('Crypt/Common/AsymmetricKey.php');
include('Math/BigInteger.php');
include('Crypt/EC.php');
include('Crypt/PublicKeyLoader.php');
include('Crypt/RSA.php');
有了这个：
require __DIR__ . '/vendor/autoload.php';
一旦你这样做了，phpseclib v3 应该可以顺利运行。您遇到的问题是因为 phpseclib v3 正在尝试自动加载引擎，但它不能这样做，因为没有自动加载器。
请注意，一旦您生成的代码开始工作，就不需要 SSH 来使用它。要让 PHPSecLib v3 为没有 SSH 的人工作，你可以做的是在本地执行 composer init 然后 composer require phpseclib/phpseclib:3.0 然后获取你的供应商目录和你的 composer.json 和 composer.lock文件并将其放入您想要的任何项目中。 IE。最终用户不会成为 运行 作曲家——您将成为 运行 作曲家。您将下载依赖项，而他们只会使用您下载的依赖项！
选项 2：手动使用 PHPSecLib2
此选项不需要 SSH。 PHPSecLib2 的功能比 PHPSecLib3 少，但它仍在积极维护。 （甚至 PHPSecLib1 也会收到定期更新。）
PHPSecLib2 没有 PublicKeyLoader class，因此您可以使用 RSA class，如下所示：
<?php
ini_set('display_errors', 1); ini_set('display_startup_errors', 1); error_reporting(E_ALL);
header("Content-Type: text/plain");
$sIncludePath = get_include_path() . PATH_SEPARATOR . '../s/phpseclib';
echo $sIncludePath."\n";
set_include_path($sIncludePath);
include('Math/BigInteger.php');
include('Crypt/RSA.php');
include('Crypt/Hash.php');
include('Crypt/Random.php');
use phpseclib\Crypt\RSA;
use phpseclib\Crypt\Hash;
use phpseclib\Crypt\Random;
function rsaEncryptionOaepSha256 ($publicKey, $plaintext) {
$rsa = new RSA;
$rsa->loadKey($publicKey);
$rsa->setHash('sha256');
$rsa->setMGFHash('sha256');
return $rsa->encrypt($plaintext);
}
function rsaDecryptionOaepSha256 ($privateKey, $ciphertext) {
$rsa = new RSA;
$rsa->loadKey($privateKey);
$rsa->setHash('sha256');
$rsa->setMGFHash('sha256');
return $rsa->decrypt($ciphertext);
}

如果有帮助，请注意测试脚本位于单独的目录中，如下所示：
inc
-> phpseclib (the PHPSecLib library with all subdirectories)
main
-> phpseclibtest.php (my test script)
PHP 版本是 7.0.33，如果这有什么不同的话。
我真的很想知道如何让 PHPSecLib 工作。如果有人能帮我弄清楚发生了什么，那就太好了。
您正在尝试使用 phpseclib v2 的说明安装 phpseclib v3。有两种选择：
选项 1：将 PHPSecLib V3 与 Composer 一起使用
此选项需要在服务器上进行 SSH 访问。
要安装 phpseclib v3，您需要 Composer。安装完成后，您可以执行 composer init 然后 composer require phpseclib/phpseclib:~3.0.
通过这样做你可以替换这个：
ini_set('display_errors', 1); ini_set('display_startup_errors', 1); error_reporting(E_ALL);
header("Content-Type: text/plain");
$sIncludePath = get_include_path() . PATH_SEPARATOR . '../inc/phpseclib';
echo $sIncludePath."\n";
set_include_path($sIncludePath);
include('Crypt/Common/AsymmetricKey.php');
include('Math/BigInteger.php');
include('Crypt/EC.php');
include('Crypt/PublicKeyLoader.php');
include('Crypt/RSA.php');
有了这个：
require __DIR__ . '/vendor/autoload.php';
一旦你这样做了，phpseclib v3 应该可以顺利运行。您遇到的问题是因为 phpseclib v3 正在尝试自动加载引擎，但它不能这样做，因为没有自动加载器。
请注意，一旦您生成的代码开始工作，就不需要 SSH 来使用它。要让 PHPSecLib v3 为没有 SSH 的人工作，你可以做的是在本地执行 composer init 然后 composer require phpseclib/phpseclib:3.0 然后获取你的供应商目录和你的 composer.json 和 composer.lock文件并将其放入您想要的任何项目中。 IE。最终用户不会成为 运行 作曲家——您将成为 运行 作曲家。您将下载依赖项，而他们只会使用您下载的依赖项！
选项 2：手动使用 PHPSecLib2
此选项不需要 SSH。 PHPSecLib2 的功能比 PHPSecLib3 少，但它仍在积极维护。 （甚至 PHPSecLib1 也会收到定期更新。）
PHPSecLib2 没有 PublicKeyLoader class，因此您可以使用 RSA class，如下所示：
<?php
ini_set('display_errors', 1); ini_set('display_startup_errors', 1); error_reporting(E_ALL);
header("Content-Type: text/plain");
$sIncludePath = get_include_path() . PATH_SEPARATOR . '../s/phpseclib';
echo $sIncludePath."\n";
set_include_path($sIncludePath);
include('Math/BigInteger.php');
include('Crypt/RSA.php');
include('Crypt/Hash.php');
include('Crypt/Random.php');

要手动降级到 PHPSecLib2 并使上述代码正常工作，您需要将 phpseclib 目录替换为位于此处 GitHub 的文件：https://github.com/phpseclib/phpseclib/tree/2.0
