A hacker has decrypted the iPhone's security chip, but your data is still safe

In order to make Touch ID on the iPhone 5s an onward secure, Apple introduced a fairly opaque piece of technology to its devices — the so-called Secure Enclave Processor (or SEP in short). This, in simple terms, is a piece of hardware found in almost every Apple-made device since the 5s which is used to keep users' private data (think passwords, fingerprints, and everything else that requires cryptography) secure, taking the form of a tiny coprocessor kept completely isolated from the rest of the device.
