CarbonCopy Posted August 24, 2009 Share Posted August 24, 2009 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?

CarbonCopy Posted August 24, 2009 Author Share Posted August 24, 2009 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?

CarbonCopy Posted August 24, 2009 Author Share Posted August 24, 2009 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.

CarbonCopy Posted August 28, 2009 Author Share Posted August 28, 2009 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 Link to comment https://forums.phpfreaks.com/topic/171636-openssl_pkcs7_sign-error-creating-pkcs7-structure/#findComment-908043 Share on other sites More sharing options...
CarbonCopy Posted August 28, 2009 Author Share Posted August 28, 2009 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 .
