The protection of personal and professional data is becoming increasingly important, and one of the ways to achieve this is by encrypting data on the hard disk.
The encryption process turns any information into incomprehensible gibberish, except for the one who has the access key
According to the dictionary of the Real Academia Española de la Lengua encrypting means transcribing with letters, numbers or signs an information or content to be protected, but in practice it means a process by which by means of a method or tool the information is converted into an unreadable data set. (without knowing the decryption key, of course).
There are several software solutions on the market to encrypt and decrypt (only by authorized persons) information. Something that can be applied to messages or emails but in this case is going to be applied to user-selected folders (or even the entirety) of a hard disk.
One of the steps in these cases involves carrying out a partition on the hard disk. so as to generate an area that can be encrypted, protecting all the data stored in it, but without affecting the entire storage space.
The best software to encrypt the hard disk.
Some of the best existing tools are as follows:
-AxCrypt: This open source tool is free and allows you not only to encrypt files but also to compress, decompress and send files. As a distinctive feature it is compatible with cloud data storage platforms such as Google Drive, Dropbox and Skydrive, allowing you to encrypt your files easily. Additionally, its installer does not exceed one megabyte, being one of the lightest on the market.
-BitLocker: Uses a powerful algorithm capable of encrypting data contained in a folder or hard drive (all or part of it, whatever the user selects).
-Diskcryptor: Allows to encrypt hard disks but also external storage drives such as CDs and DVDs. It uses different encryption algorithms (AES, Twofish, Serpent…).
-HTTPS Everywhere: In this case it is not even necessary to install a program since it allows sending encrypted information through the browser (at the moment it is only available for use with Chrome and Firefox). It is able to encrypt all data transfers made from the Internet browser.
-VeraCrypt: With up to 5 levels of encryption, it is the successor to TrueCrypt. It works on Mac, Windows, Linux and Mac OS operating systems, being an open source program. It is able to encrypt even the part of the hard disk where the operating system is installed, as well as, of course, external hard disks and USB drives.
