[Qt-interest] Strict Plugin Loading with -buildkey

[Jason Todd Slack-Moehrle]

Hi All,

I am developing an application that is plugin based.

Can anyone explain why I might want to configure using -buildkey  
<key>? I understand that my app would only load plugins that match  
keys. But why do this? Security reasons?

What do I use as a key? do I make it up? Can I use anything? What  
about something like: abcderg999xyz? (just trying to get what I can  
and cannot use, any specific format, etc)

Thoughts are appreciated.

-Jason
