GnuPG returns false in PHP

Navigation

I'm using the GnuPG module in PHP and tested it exactly with this code: 

$keydata = '-----BEGIN PGP PRIVATE KEY BLOCK-----
Version: BCPG C# v1.6.1.0

-----END PGP PRIVATE KEY BLOCK-----';

$res = gnupg_init();
$info = gnupg_import($res,$keydata);
var_dump($info);
  

This private key was generated for testing!

Result: 

bool(false)

I tested with this key above and also with the "original" key, both have $info as false , which is not expected. Second the documentation (and the comment 9 years ago) on link was to be displayed information about the key that was imported.

No error is reported in the logs and the module is installed properly and with all the necessary dependencies, apparently.

Does this extension no longer work or is something wrong?

I have found a solution. : D

Problem Cause:

PHP / NGINX was not able to access the folder where the file was imported and so false was displayed.

Try running the same script as root using PHP-CLI and you probably will not have the problem.

Solution:

Enter a folder outside the web access: 

cd /usr

Create a folder for example: 

mkdir .nomelegal

Give NGINX permission: 

chown -R nginx .nomelegal
chgrp -R nginx .nomelegal

If you're using Apache, change nginx to www-data , I believe that's it.

Then determine the location in PHP by adding this: 

<?php

putenv("GNUPGHOME=/usr/.nomelegal");


$keydata = '...';

$res = gnupg_init();
$info = gnupg_import($res,$keydata);
var_dump($info);

If everything is right now PHP is able to read and write inside the folder so you can import public and private keys!

Note:

I do not know if it is necessary, but Centos does not run gpg-agent automatically, so you should run: 

gpg-agent --daemon --use-standard-socket

This was used to generate keys, I do not know if it's necessary for GnuPG in PHP.
