Tai vis tik mes apie bootrom'a snekame? 4S bootrom'e kazkokia skyle turi? Galima kazkur apie tai 
paskaityti?

Kas lauze sake.

Padarysiu copy paste del taves, aisku as ne ant edge.

However these protection mechanisms are not applicable at kernel level (AppleKeyStore method) and it 
leads to bruteforce attacks. To make brute force attacks less practical, passcode key derived from 
the user passcode is tied to hardware UID key. So the brute force can only be performed on the 
device and it is not possible to prepare pre compute values (like rainbow tables) offline.

Detalesnes info noresi ir turesi laiko - susirasi.
