title: What is the best way to encrypt files in AES-256 with PHP?
body: <p>I found some tutorials online that could help but I am not sure there the best options. I would like to encrypt the file with a highly secure algorithm (I am a bit paranoid) but at the same time I am looking for speed (I know it's a bit of a contradiction)... So I chose AES-256... But what is the best way to use AES-256 with PHP to encrypt files?</p>
