![]() ![]() Using brute-force methods-say, a supercomputer trying one key after another in an effort to decrypt it-could take an average of many trillions of years to break it-far longer than the current age of the universe. It takes the data through multiple permutation rounds in the encryption process. Even the standard 256-bit AES encryption (which uses a 256-bit key) is essentially uncrackable. Most mainstream encrypted SSDs and hard drives provide what's known as AES 256-bit hardware-based encryption, while most hyper-secure keypad-accessible drives utilize XTS-AES 256-bit hardware-based encryption.įor good reason, AES is considered the gold standard in drive encryption. A Guide to Hardware-Based EncryptionĮncryption is the process of taking readable text or data and encoding it using a key-a random string of bits, generated by an encryption algorithm-so that only someone in possession of the key can decrypt it. Read on for our lab-tested favorites, followed by information about the different types of secure and encrypted drives you might encounter and their features. ![]() We've outlined below our top picks among the encrypted hard drives we've tested.
