Hi, I have devices that I can configure using encrypted XML files. Basically, these devices browse a web server to get specific file.
We can create a plain text xml file on our web server like the following: <myxml> <param1>xxxx</param1> <param2>yyyy</param2> <param3>zzzz</param3> </myxml> Then we can use openssl to encrypt this file on our Apache+PHP web server with the following command: openssl aes-256-cbc -e -in plain_file.xml -out encrypt_file.xml -k 1234123412341234 So I'm trying to figure out how to do this "on the fly" using PHP. I see that PHP has support for openssl (http://us2.php.net/openssl) but all the examples/docs show file operations and we don't want to touch the file system. Would somebody have a sample PHP script to help with this? Or the equivalent command to take data from stdin and write the encrypted data to stdout? I have the following test code, but it returns different encrypted data every time. My devices accept this data every 10 to 15 tries which I don't understand. <?php // test.xml is just a plaintext xml file $output = shell_exec("openssl aes-256-cbc -e -in test.xml -k 1234123412341234"); echo "$output\n"; ?> I would like to get rid of the shell_exec all together or at the least figure out how to make the openssl command NOT use the test.xml file and return the same encrypted data all the time. Thanks a bunch, Shanon ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager [EMAIL PROTECTED]
