openssl_pkcs7_sign() error creating PKCS7 structure!

[CarbonCopy]

I am building my own shopping cart that has to work in a situation where all shell functions are disabled and Apache is in a chroot environment (Created with mod_chroot). Everything works great for PHP and the shopping cart EXCEPT for the encryption standards. I found a really nice script that had been working before the chroot jail, and now it is broken. I do not know what the error means or how to fix it. Any ideas people?

The nice script for encryption i am using can be found at the below link:

Either the temporary dir used by the script or /dev/{u,}random, are not available within the jail.

Well open_basedir has restricted access outside of the website directory, but I moved the tmp folder to /chroot/www/domain.tld/.tmp which is owned by apache:apache and chmod'd to 700. No idea about the dev thing, I definitely didn't create it. How could i do it?

Fixed the problem, for any further googlers, I used mknod /chroot/dev/random c 1 8 to recreate the required files in my chroot jail.

I've created urandom and random, but this problem still occurs. But only randomly. It works the majority of times but if I keep refreshing the page I get the error every now and then

When the error occurs the following "debug" code produces no output

 

ini_set("display_errors","on");
error_reporting( E_ALL );

for ($i = 0; $i < 100; $i++) {
openssl_public_encrypt ("BBBBBBBBBBBBBBBBBBBBBB",$strong,file_get_contents($MY_CERT_FILE));	
openssl_private_decrypt($strong,$dec,file_get_contents($MY_KEY_FILE));
echo $dec . "<br />";
}
