Actually, it's harder than breaking the enigma code. . . by quite a few orders of magnitude. We're talking several decades of advancement in encryption, Dr. Ursus. This is not any mere substitution code or even anything linear. The iPhone is protected by a 256bit Advanced Encryption Standard encryption. The new iPhones passcodes are not stored on the devices at all. Instead, the passcodes are stored as a one-way hash inside an unreadable Secure Enclave that cannot be read from outside the device by any known means and that one-way hash is stored in a buried EEPROM that will be destroyed by any attempt to reach it.
Thanks,I didn’t make myself clear. I meant the info that was derived.
