[Apache/PHP] gnupg for php (with apache)

[Tornevall]

Welcome to yet another howto. Those instructions should probably solve stuff that is impossible to find "bundled" at any search engine. There's only questions, questions and questions, but never answers. So here we go!


Bundled installation of gnupg into PHP, step by step. You can probably also build gnupg as an extension, but I chose to bundle the package. You should also be aware of the path to your keys if you start your server with a root account, or if you run apache with suid-users. You may have to give gnupg some information about where it can find the keys, especially if root is involved.

$gnupghome="/home/users/gnupg/.gnupg";
putenv("GNUPGHOME=$gnupghome"); 

Requirements and useful links

Physical access to a webserver or a webhotel that support gnupg.

gnupg (http://www.gnupg.org/)
gpgme (http://www.gnupg.org/gpgme.html)
php gnupg (http://pecl.php.net/package/gnupg)

libs and addons that might be needed
libgpg-error (http://www.gnupg.org/related_software/libgpg-error/)
re2c (http://sourceforge.net/projects/re2c)

PHP Bundling

cd php-source/ext
pecl download gnupg
tar zxvf gnupg-1.3.1.tgz
mv gnupg-1.3.1 gnupg
cd ..
mv configure configure_the_backup_plan
./buildconf --force

A lot of work here

Now let's check if we have the gnupg-switches
./configure --help

At least I have:

--with-gnupg=dir Include gnupg support

configure --with-switches

Now, this shows up

configure:56876: checking for gnupg support
configure:56915: result: yes
configure:56927: checking for gnupg files in default path
configure:56932: result: found in /usr/local/include

make
make install

And phpinfo() says:




Probably, if everything works properly, you could also use this command to make it easier for yourself (if you have access to pear and pecl):

pecl install gnupg
