WebNov 6, 2024 · Randomness in Cryptography As we’ve discussed in the past, cryptography relies on the ability to generate random numbers that are both unpredictable and kept secret from any adversary. But “random” is a pretty tricky term; it’s used in many different fields to mean slightly different things. WebJul 29, 2024 · Encryption relies on passcodes Passcodes and the data protection feature are inextricably tied in iOS because a user's passcode is linked with the device's UID. An attacker cannot access data in the protected classes without the passcode, which is why organizations should always require passcodes on their managed iOS devices.
