Extend File Upload to utilize mcrypt

[eluser]dionysus[/eluser]
Is there a way to enable/modify the file upload class to utilize mcrypt to encrypt files that are being uploaded to the system? Not just the filename, but the file itself?

thanks!

You can extend base Upload class to add this function, CodeIgniter has class for encrypting data (defaults to mcrypt) - http://ellislab.com/codeigniter/user-gui...ption.html

I decided to forgo modifying the upload class. What I did was after the file was uploaded, open the file, encrypt it, and write it out again.

Code:

$f=file_get_contents(BASE_PATH.$fileFullPath) or die ('no gfc');
$encf=$this->encrypt->encode($f,$this->e_key) or die ('no encrypt');
$nf=fopen(BASE_PATH.$fileFullPath,"r+") or die ('no open ');
$fw=fwrite($nf,$encf) or die ('no fwrite');
fclose($nf);

That works too. Also, when you upload a file using CodeIgniter's File Upload class, instead of file_get_contents(BASE_PATH.$fileFullPath), you can do this:

Code:

$file_data = $this->upload->data();
$file_contents = file_get_contents($file_data['full_path']);
