Hello!
Could you help, please?
I want create a file structure as the "estructura.jpg".
I want to create a file DF and when I try to access to it, it requests
me the PIN that there is in the file PIN.
I want that the file of PIN is a code. I want that the file of PIN one
cannot read. Only to verify. Also, I want that the
file of PIN can only be modified starting from a secret key.
My question is: How do I have to define the access conditions and the
file of PIN?
Thanks
