That should give you an idea of how ironclad AES encryption is, at least in the face of a brute-force attack.Įncrypted mainstream external drives often let users create a password-protected vault into which they can drop files or folders to be encrypted (by AES or other methods). 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. Best Hosted Endpoint Protection and Security Software.
