Details

This patch allows you to open any bitmap
backdrop size or smaller and display it.
It wil display a random 2 digit password
before the image. To exit select power
on the sansa and enter the password.
Use select on the sansa to exit without
a password (backdoor)
Just a proof of concept for password protection.
You could make a WPS screen to display.
select a bmp and use open with to set the config file
and then run the plugin.

"Nice" password protection, if I press power it asks for the password but if I press select it quits without asking. (Irony)

yes select is a backdoor.
Easy to lock it down, remove some code, but I forgot the password
so many times while testing I put in the backdoor.
The matrix_pass  FS#7920  screensaver has no backdoor.

Even without a backdoor, what's stopping someone resetting the device to access it? Don't know if the Sansa has a hardware shut down/reset, but many targets do...

This provides as much protection as a win98
password protected screensaver. This is only
to keep honest people from poking where they should not.
