This doesn't mean there won't be exploits, but it means that the chances that Shamir or one of the other hotshot cryptanalysts is going to bring out a paper tomorrow that invalidates all your work are very small. Moreover, there are known exploits against 3DES (even if they aren't terribly helpful), whereas massive scrutiny by cryptanalysis worldwide (while Rijndael was becoming AES) has turned up nothing so far. Brute-forcing a 128-bit keyspace would take several centuries, even taking into account Moore's law, so the difference between it and 3DES's 168 bits isn't relevant. (To those who still believe the NSA weakened DES, go read your Schneier.)ĪES-128 is a new algorithm, but feels good. In the case of DES, it was refined by the oft-maligned NSA to resist differential cryptanalysis, leaving it resistant against all but brute-force until linear cryptanalysis was 'discovered' in the mid-90s.

It's only relevant if brute force is the fastest way to crack the cipher, which is very rarely the case.
However, the keyspace of an algorithm is only one of its strengths. Proper 3DES implementations use three independent keys for an effective keyspace of 2^168. It's also greater than 3DES using two keys (one for the first and third stage, one for the second, so 2^112). Yes, this is a greater range than DES (2^56). When you unmount the disk image, the files will be locked and no one will be able to access them unless they have your encryption password.128-bit AES allows for 128-bit keys, so yes, in decimal, 3.4e38-somethingorother (2^128). The files will be available to use and any files you save to the disk image will be encrypted. Whenever you want to work with your encrypted files just mount the disk image and enter your password. You can encrypt individual files by creating an encrypted file container, or disk image.

#MAC OS X ENCRYPTION PROCESS PASSWORD#
The disk will be encrypted once you enter your password of choice-be sure to use a secure one! You may have to wait several minutes for the contents of your disk to be encrypted, depending on the size of your drive and its speed.ĭon’t lose your password! If you do, you won’t be able to access any files on the encrypted drive. Ctrl+click or right-click the drive in the Finder sidebar and select the Encrypt option. To encrypt a drive, simply open the Finder and connect the drive to your Mac. It functions like BitLocker To Go on Enterprise editions of Windows, but it’s available to all Mac users. The contents of the drive will be encrypted with a passphrase you choose, and no one will be able to access them without that passphrase. With macOS you can also encrypt entire external drives. This can take days, so consider keeping your Mac awake overnight. Once you’re done configuring FileVault, your Mac will begin encrypting your drive in the background. Keep this key somewhere safe, because it’s the only way you can recover your files should you lose access to the local accounts on your Mac with permission to decrypt the drive. If you’d rather not tie your encryption to a (potentially hackable) online account, that’s not a problem: you can opt for a recovery key instead. This allows you to regain access to the drive if you forget the username and password for the local account on your Mac. Click the “Turn On FileVault” option to enable and configure FileVault.īy default, FileVault will ask you for your Apple ID. To enable FileVault, click the Apple icon on the menu at the top of your screen, select System Preferences, and click the Security & Privacy icon. Your drive will be locked again when you shut down your Mac. When you turn on your Mac, you’ll have to sign in with one of those user accounts before your drive is unlocked. You can choose which user accounts have the ability to unlock your disk. (Without FileVault enabled, anyone with physical access to your Mac could remove its hard drive and view your files, because they’re stored in an unencrypted form.) Someone who gains access to your Mac, removes your hard drive, and attempts to view your files won’t be able to see anything without your encryption key. When you enable FileVault, your files are stored on your hard drive in an encrypted, seemingly scrambled format. The FileVault feature allows you to encrypt your Mac’s entire hard disk.
