Hi, this is my first release of anything. (Not my first app, but release) So go easy on me!
Any way it is called Locked Out! V1.0 which is a non-bricking, simple to use security app coded in lua.
Usage of this app will not brick your psp, but the installation requires luaplayer hm 8 drivers to be installed, which writes to flash, and the risk with writing to flash

... but if done right, should not brick!
The actual program will not brick. Just be sure to back up Flash1! Everything you need will be in the detailed readme that is included.
The starting password is "password".
From the readme:
This is meant to be a simple, non bricking security app.
NOTE: This will not protect from people who are seriously determined to get into your psp, and/or just know what they are doing. It is meant to protect from those people who just pick up your psp without permission and play it, or change setting exc. This will annoy them and above that, simply make them put it down and give up....
If this recieves enough intrest, I can make future versions of it, which may include:
Changing password manually through the psp.
Sounds, pics, anything like that.
Higher security.
And many other things.
Please try and give feedback, and suggestions.
Thanks,
Coolbeans.
