Its downside is slowness and ease of decrypting and leaking data, since it uses shorter block lengths. Represents the triple data encryption standard, and is a symmetric key encryption system that uses three individual 56-bit keys, which ends up encrypting data three times, ultimately turning into a 168-bit key. Its advantage is to not be a patented technology, which greatly lowers the cost for those who will use it. Unlike AES, the number of rounds in Twofish is always 16 rounds. It is a symmetric block cipher of 128-bit to 256-bit that implements rounds of encryption to turn plaintext into ciphertext. Represents the acronym Advanced Encryption Standard and it is a symmetric encryption algorithm, using a block cipher, which encrypts data one fixed-size block at a time rather than bit-by-bit, and being considered one of the most secure in the world, to the point that it is used by the US government to protect their confidential information. There are four other encryption systems that deserve a quick mention: However, encryption is not limited to Bitlocker, although this is possibly the best known and most widespread encryption system in the corporate world, due to the use of Windows platform. Select Turn on BitLocker and then follow the instructions. It is not available on Windows 10 Home edition.ģ. Note: you will only see this option if BitLocker is available for your device. In Control Panel, select System and Security, and then under BitLocker Drive Encryption, select Manage BitLocker. Or you can select the Start button, and then under Windows system, select Control Panel. In the search box on the taskbar, type Manage BitLocker and then select it from the list of results. Sign in to your Windows device with an administrator account (you may have to sign out and back in to switch accounts).Ģ. TO TURN ON STANDARD BITLOCKER ENCRYPTIONġ. If device encryption is turned off, select Turn on. You may be able to turn on standard BitLocker encryption instead.ģ. If Device Encryption does not appear, it is not available. Select the Start button, then select Settings > Update & Security > Device Encryption. Sign in to Windows with an administrator account (you may have to sign out and back in to switch accounts).Ģ. With Bitlocker it is possible to enable encryption of a device or enable Bitlocker’s default encryption, as shown below:ġ. However, considering that we are in the Windows 10 era, it is important to note that Windows 10 Home Edition does not have Bitlocker. It has been available since Windows Vista and, afterwards, through Windows 7, 8, and 10. Surely, Windows system users are unaware that it has an encryption system called Bitlocker. However, with the exception of information technology professionals, encryption is ignored by most people who barely even hear anyone mention it in a conversation or article. Therefore, encryption turns out to be a great ally in information security, as it protects any kind of data from undue access, especially personal data of an organization’s internal as well as external data subjects. The result of this process is encrypted information, also known as ciphertext. Encryption is the process of turning information into text by using an algorithm (called a cipher) in order to enable anyone to read it except those with a particular identification, usually referred to as a key.
