The Problem With Disk Encryption

Full disk encryption provides incredible data protection for personal devices. If you haven’t enabled FileVault on your Mac, Windows Device Encryption on your PC, or Android Device Encryption on your phone, please go do it now (iOS encrypts storage by default). It’s easy, efficient, and secure. You will likely never notice the difference in usage or performance. Seriously. This is a no-brainer.

How a quantum computer could break 2048-bit RSA encryption in 8 hours

Many people worry that quantum computers will be able to crack certain codes used to send secure messages. The codes in question encrypt data using “trapdoor” mathematical functions that work easily in one direction but not in the other. That makes encrypting data easy but decoding it hugely difficult without the help of a special key.

What is a side channel attack? How these end-runs around encryption put everyone at risk

Brute force attacks on cryptography could take billions of years, which no one has to spare. Maybe you live in a country where rubber hose cryptography is, shall we say, frowned upon. Hacking a target's endpoint is an option, but what if you get caught? Better to use an attack that leaves no forensic traces behind.
