phpseclib不适用于来自终端的php5-cli [英] phpseclib not works with php5-cli from terminal

问题描述

我在raspbian（debian操作系统）上安装了php5-cli软件包，并下载了 phpseclib 在/ cli /目录中。
我通过以下方式创建了一个测试文件，以使用公共密钥（在我具有相同库的apache服务器中生成）对文本进行加密：

I installed php5-cli package on my raspbian (debian OS) and I downloaded phpseclib in /cli/ directory. I created a test file to encrypt text with a public key (generated within my apache server on which I have the same library) in this way:

    include('libs/Crypt/RSA.php');
    $rsa = new Crypt_RSA();
    $rsa->loadKey($myPublicKey);
    $encrypted = $rsa->encrypt("my text");
    echo "result: " .$encrypted;
    

如果我尝试输入 php test.php ，则结果变量为空。为什么？这是由于我使用php5-cli而不是php5从终端e执行文件吗？
如何获得此加密操作的结果？
谢谢。

If I try to type php test.php the result variable is empty. Why? It's due to the fact I execute the file from terminal e with php5-cli instead of php5 ? How Can I obtain the result of this encrypting operation? Thanks.

推荐答案

您提供的源代码正确。如果 $ encrypted 的值为空，则可能是由于 loadKey 中提供的密钥不正确。

The source code you have provided is correct. If the value of $encrypted is empty, it's possible due to an incorrect key supplied in loadKey.

根据文件 RSA.php 中的注释，该命令将返回 false 如果密钥无效：

According to the comments in the file RSA.php, then the command will return false if the key is invalid:

/**
 * Loads a public or private key
 *
 * Returns true on success and false on failure (ie. an incorrect password was provided or the key was malformed)
 *
 * @access public
 * @param String $key
 * @param Integer $type optional
 */
function loadKey($key, $type = false){
    ... 
}
