使用php curl用私钥连接到sftp

使用php curl用私钥连接到sftp

• php

I need to write a php script that can connect to a sftp server, get the list of the directories and files in the server, and later download a specific file. I was given the ppk file (I assume this is the private key authentication file) for the authentication part.

I read in a few places that curl can do this.. but I'm not entirely sure how to do it. I tried copy pasting the code from here but my understanding was the code utilizes public keyfile instead of private key.

So here's what I tried to connect to the sftp server

1.  
   $ch = curl_init();
2.  
   curl_setopt($ch, CURLOPT_VERBOSE, TRUE);
3.  
   curl_setopt($ch, CURLOPT_URL, 'sftp://233.42.20.115/');
4.  
   curl_setopt($ch, CURLOPT_PROTOCOLS, CURLPROTO_SFTP);
5.  
   curl_setopt($ch, CURLOPT_SSH_PRIVATE_KEYFILE,'megpxl_private.ppk');
6.  
   curl_setopt($ch, CURLOPT_SSH_AUTH_TYPES,CURLSSH_AUTH_AGENT);
7.  
   $output = curl_exec ($ch);
8.  
   print_r($output);

The output prints nothing.. so what should I do to actually connect to this sftp properly?

====Update==== Now I'm trying to use phpseclib. Here's my code:

1.  
   require_once 'phpseclib/Net/SSH2.php';
2.  
   require_once 'phpseclib/Net/SFTP.php';
3.  
   require_once 'phpseclib/Crypt/RSA.php';
4.  
   require_once 'phpseclib/Crypt/RC2.php';
5.  
   require_once 'phpseclib/Crypt/RC4.php';
6.  
   require_once 'phpseclib/Math/BigInteger.php';
7.  
    
8.  
   set_include_path('phpseclib/Net/');
9.  
    
10.  
    $privatekey = file_get_contents('sftp_private.txt');
11.  
     
12.  
    $rsa = new Crypt_RSA();
13.  
    $rsa->loadKey(file_get_contents("private.ppk"));
14.  
    $sftp = new Net_SFTP('233.12.20.225', 22);
15.  
    if (!$sftp->login("myUserName", $rsa)) {
16.  
    exit('Login Failed');
17.  
    }
18.  
    print_r($sftp);

But all I got was this message:

No compatible server to client encryption algorithms found in /var/www/html/phpseclib/Net/SSH2.php on line 1375

=============Update: This works!=================

1.  
   require_once 'phpseclib/Net/SSH2.php';
2.  
   require_once 'phpseclib/Net/SFTP.php';
3.  
   require_once 'phpseclib/Crypt/RSA.php';
4.  
   require_once 'phpseclib/Math/BigInteger.php';
5.  
    
6.  
   set_include_path(get_include_path() . PATH_SEPARATOR . 'phpseclib');
7.  
    
8.  
   $privatekey = file_get_contents('sftp_private.txt');
9.  
    
10.  
    $rsa = new Crypt_RSA();
11.  
    $rsa->loadKey(file_get_contents(mykey.ppk"));
12.  
    $sftp = new Net_SFTP('223.22.20.122', 22);
13.  
    if (!$sftp->login("usrPMEGPXLtxn", $rsa)) {
14.  
    exit('Login Failed');
15.  
    }
16.  
     
17.  
    print_r($sftp->nlist()); // == $sftp->nlist('.')
18.  
    print_r($sftp->rawlist()); // == $sftp->rawlist('.')
19.
