Like a options for protection (if software and hardware support it) - Encrypted block protection. Entry ID: 45632073. Best regards, Hristo Mihalev

There are possibilities eithe to steal MMC or someone to 'find' the way to know the password. If someone knows the way to find the password he does't care about your program because can write own one. best regards, Hristo Mihalev
