Windows 10 BitLocker enable Encryption Method

BitLocker may be a full volume encryption method feature introduced with Microsoft Windows versions beginning with Windows Vista. it’s designed to guard data by providing encryption method for entire volumes.

when you store sensitive data on your computer, it’s crucial that you simply take the required steps to guard that data (especially if you employ a laptop or tablet).
This is often not just to prevent the NSA from accessing your files, but it’s more about preventing your private data from falling into the incorrect hands within the slightest change you lose your device, or it gets stolen.
One way you’ll protect your data is by using the Windows 10 BitLocker encryption method. Briefly, encryption is essentially the method of creating any sort of data unreadable by anyone without proper authorization.
If you employ encryption to scramble your data, it’ll still be unreadable even after sharing it with people. In other words, only you with the proper encryption key can make the info readable again.
Windows 10 BitLocker, almost like previous versions, includes BitLocker Drive Encryption, a feature that permits you to use encryption on your PC’s disk drive and on removable drives to stop prying eyes from snooping into your sensitive data.

Things you should know before diving into windows 10 BitLocker

  1. BitLocker Drive Encryption only works on Windows 10 Pro and Windows 10 Enterprise.
  2. For best results, your computer must be implemented with a Trusted Platform Module (TPM) chip. This is a unique microchip that allows your device to maintain advanced security features.
  3. You can use BitLocker without a TPM chip by applying software-based encryption, but it needs some extra steps for additional authentication.
  4. Your computer’s BIOS must support TPM or USB devices while startup. If this isn’t the case, you’ll need to verify your PC manufacturer’s support website to perceive the latest firmware update for your BIOS before attempting to set up BitLocker.
  5. Your PC’s hard drive must carry two partitions: a system partition, which carries the necessary files to start Windows, and the partition with the operating system. If your computer doesn’t satisfy the requirements, BitLocker will produce them for you. Additionally, the hard drive partitions must be formatted with the NTFS file system.
  6. The process to encrypt a whole hard drive isn’t difficult, but it’s time-absorbing. Depending on the amount of data and size of the drive, it can take a very long time.
  7. Make sure to retain your computer connected to a continuous power supply during the whole process.
