PHP安装gpg扩展

1.首先我们去下载gpg的源码包：

http://pecl.php.com/package/gnupg

我下载的是：gnupg-1.3.6.tgz

解压之后，cd到目录中phpize，然后./configure。

2.

andy@AndyMacBookPro:~/Downloads/gnupg-1.3.6$ phpize

----------------------------------------------------------------------
Libraries have been installed in:
   /Users/andy/Downloads/gnupg-1.3.6/modules

If you ever happen to want tolink against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `DYLD_LIBRARY_PATH' environment variable
     during execution

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------

Build complete.
Don't forget to run 'make test'.andy@AndyMacBookPro:~/Downloads/gnupg-1.3.6$

4.我们可以看到so文件已经生成，我们把so文件移动到php的扩展目录中：

andy@AndyMacBookPro:/usr/lib/php/extensions/no-debug-non-zts-20100525$ sudo cp /Users/andy/Downloads/gnupg-1.3.6/modules/gnupg.so ./

之后我们到php.ini中添加此扩展：

extension = gnupg.so

之后我们就可以在php中使用gunpg扩展了：

$url = 'http://192.168.2.85/2015/09/20/加密文件.csv';
$data = file_get_contents($url);
$data = mb_convert_encoding($data, 'UTF-8', 'GBK');

$encrypted_text = $data;
$res = gnupg_init();
gnupg_adddecryptkey($res,"ABCFA237F71C57CA2042439F93704A63BCC8A2F","12345678");
$plain = gnupg_decrypt($res,$encrypted_text);
var_dump($plain);exit;
