PHP

It is not uncommon to want your site users to be able to download files, but only the specific ones you want them to. To make this possible, you need to store the files somewhere offline, where there isn't a direct URL to them, and you have to be able to insert security.

Sometimes, you need to generate a temporary password for a new user. Something that meets your security requirements, and is painful enough to make the user change it as soon as they log on. I've got just the ticket.
