I've faced the error

Warning: gnupg_import(): import failed " while importing the public key and I did not have any luck solving this issue , when use (iis server-win8 - php version 5.5.12) with (php-5.5-windows-extensions/php_gnupg-1.3.3-5.5-vc11-x86/).

The question is, can i use php_gnupg (PGP (Pretty Good Privacy)) with IIS server to encrypted file ?

php_gnupg is a compatible with iis server !!!!

NOTE:

This problem does not appear when use XAMPP sever.

Test script:
---------------
$res = gnupg_init();
$public_key_sender = file_get_contents('public_key_sender.asc', true);
$private_key_sender = file_get_contents('public_key_sender.asc', true);
$private_key_sender_ = gnupg_import($res,$private_key_sender);
$public_key_sender_ = gnupg_import($res,$public_key_sender);

Expected result:
----------------
when use iis server (php version 5.5.12)
( ! ) Warning: gnupg_import(): import failed in C:\inetpub\wwwroot\index.php on line 18

Actual result:
--------------
when use xampp server (php version 5.5.12)
