| Aug 25, 2016 at 14:41 | comment | added | Yorick de Wid | This is not going to fit in an comment; BitLocker encrypts the drive with AES-128-CBC by default. CBC (but also XTS since Windows 10) allows for random IO, so individual files can be accessed per sector. All the blocks within a sector use the same master key, a password hashed version of your BitLocker password. For a private key, the process goes slightly different. This explains why the entire drive needs to be decrypted first, before you can re-encrypt again. I'd understand why you asked the question, and however it is in theory possible to setup encryption in such a way that you can easily | |
