Data encryption is a method of hiding the original meaning of a document or message, which ensures that its original appearance is distorted. In simple words, this method is also called coding, since with the help of special programs or manually your text is translated into code that is incomprehensible to an outsider. The procedure itself depends on the sequence of changes. Such a sequence is usually called an algorithm.

Data encryption is referred to as cryptography. This science is being carefully studied by the world's intelligence organizations, and new cryptographic algorithms are being solved and created every day.

Encryption methods were known in ancient times, when Roman military leaders sent important letters in encrypted form with messengers. The algorithms were primitive back then, but they successfully confused enemies.

Unlike those times, we are not military leaders, but we have enemies. They are scammers who are eager to get our hands on data that is important to us. These are the ones that should be protected in any way.

The flash drive has become the most popular storage device today. Even huge corporations transfer important, confidential data on this type of media. The demand for flash drives has led scientists to the issue of protecting data on them. For this purpose, programs were invented that encrypt information on the media using a secret key known only to the real owner. This encryption of data on a flash drive is very reliable and will help protect important information from prying eyes.

Experts consider TrueCrypt to be the most popular data encryption program. It was created on the basis of E4M (Encryption for the Masses), the first version of which was released back in 1997. The author is considered to be the Frenchman Paul Rox. Today, the program is used by millions of people and many businesses to encrypt data.

In addition to protecting information on flash media, many are also interested in encrypting data on disk. After all, people often want to “hide” some documents from prying eyes. Queries in search engines confirm this, so many companies have begun to develop special programs. Today there are many different programs that encrypt data. They use various cryptographic algorithms, the most famous are DES, AES, Brute Force and others.

Data encryption not only helps protect information, it also acts as a “compressor.” Many archivers save disk space using encryption. For example, the well-known WinRAR uses AES with a key length of 128. Many users store data on their computer only in archived form, and each archive is protected with a password. This guarantees them not only more free space, but also protection of important data from scammers.

With the development of the Internet, it is not difficult for a well-trained hacker to hack into an unprotected computer and get the information he needs. Therefore, experts recommend encrypting all data that is important to you.
