Check/compare password on infield update

program check for compatibilty and security reasons:
I search for a method to check if a password protected compiled mf-project (hex) to load has the correct password.
Is there a way to realize such operation before mf-ghi g400 in field update?

Crate your own file format that is encrypted and then your app will decrypt and load properly.

@ Gus - very good idea.
is there any lock on the device to permit any upload operations by net mf deployment tool?

No but this is the most requested feature. We need to take a serious look into it.
