![]() ![]() ![]() Because of this some software uses drivers to accomplish tasks other than talking to devices, such as Belarc Advisor's BANTEXT driver. Truecrypt sticks itself between the filesystem driver and the controller driver, intercepting blocks of data and encrypting/decrypting them before they are passed to the lower/upper layer.ĭrivers operate in kernel mode with full access to the machine. This is a Good Thing(tm) because an operating system can use the same filesystem software on any storage device. This filesystem driver translates those high-level operations to read/write requests for specific block numbers by invoking a lower-level "controller driver" that actually sends/receives commands to the controller of that specific device. So, you'll have a "filesystem driver" that understands the specific filesystem being used, whether it's NTFS, FAT, ext4, or whatever. Application programs deal with files in terms of opening, reading, writing, and closing specific files. This is the highest block number for that drive.)Ĭonsequently, there is a small software stack with regard to filesystems on most, if not all, operating systems. (Most modern hard drives have an "LBA" number on the sticker. The "block level" is required because mass storage devices do not understand anything about files, they only understand reading and writing blocks of 512 or 4096 bytes. He loves long walks on virtual beaches, playing worker placement board games with inconsequential themes, and spending time with his family and menagerie of pets and plants.Truecrypt requires drivers because it operates on the block level. ![]() If you're looking for him after hours, he's probably four search queries and twenty obscenities deep in a DIY project or entranced by the limitless exploration possibilities of some open-world game or another. While his days of steering students toward greatness are behind him, his lifelong desire to delight, entertain, and inform lives on in his work at How-To Geek. In addition to the long run as a tech writer and editor, Jason spent over a decade as a college instructor doing his best to teach a generation of English students that there's more to success than putting your pants on one leg at a time and writing five-paragraph essays. In 2023, he assumed the role of Editor-in-Chief. In 2022, he returned to How-To Geek to focus on one of his biggest tech passions: smart home and home automation. In 2019, he stepped back from his role at Review Geek to focus all his energy on LifeSavvy. With years of awesome fun, writing, and hardware-modding antics at How-To Geek under his belt, Jason helped launch How-To Geek's sister site Review Geek in 2017. After cutting his teeth on tech writing at Lifehacker and working his way up, he left as Weekend Editor and transferred over to How-To Geek in 2010. He's been in love with technology since his earliest memories of writing simple computer programs with his grandfather, but his tech writing career took shape back in 2007 when he joined the Lifehacker team as their very first intern. Jason has over a decade of experience in publishing and has penned thousands of articles during his time at LifeSavvy, Review Geek, How-To Geek, and Lifehacker. Prior to that, he was the Founding Editor of Review Geek. ![]() Prior to his current role, Jason spent several years as Editor-in-Chief of LifeSavvy, How-To Geek's sister site focused on tips, tricks, and advice on everything from kitchen gadgets to home improvement. He oversees the day-to-day operations of the site to ensure readers have the most up-to-date information on everything from operating systems to gadgets. Jason Fitzpatrick is the Editor-in-Chief of How-To Geek. VeraCrypt takes care of everything, keeping the files temporarily in the RAM, sweeping up after itself, and ensuring your files remain uncompromised. When you're done working with them, you can just unmount the volume. All the files within the container are encrypted, and you can mount it as a normal drive with VeraCrypt to view and edit the files. With VeraCrypt's on-the-fly system, you can create an encrypted container (or even an entirely encrypted system drive). Related: How to Set Up BitLocker Encryption on Windows TrueCrypt is now discontinued, but the project has been continued by a new team under a new name: VeraCrypt. Without on-the-fly encryption, actively working with encrypted files is an enormous pain and the outcome is usually either that people simply do not encrypt their files or they engage in poor security practices with their encrypted files because of the hassle of decrypting and encrypting them. TrueCrypt was a popular open source, on-the-fly encryption application that allowed you to work with encrypted files as you would work on files located on a regular drive. ![]()
