Data encryption is a method of hiding the original meaning of a document or message, which ensures the distortion of its original form. In simple words, this is a way to protect information. This method is also called coding, because with the help of special programs or manually, your text is translated into a code incomprehensible to an outsider. The procedure itself depends on the sequence of data type changes . Such a sequence is usually called an algorithm.
Data encryption is referred to as cryptography. This science is carefully studied by world intelligence organizations, and every day new cryptographic algorithms are unraveled and created.
Encryption methods were known in antiquity, when the Roman military commanders transmitted important letters in encrypted form with messengers. Algorithms were then primitive, but successfully confused enemies.
Unlike those times, we are not military leaders, but we have enemies. They are scammers who are eager to get data that is important to us. Here they should be protected in any way.
A flash drive today has become the most popular repository of information. Even large corporations transmit important, confidential data on this type of media. The demand for a flash drive has led scientists to the issue of protecting data on them. For this, programs were invented that encrypt information on the medium using a secret key known only to the real owner. Such encryption of data on a USB 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, based on E4M (Encryption for the Masses), the first version of which was released back in 1997. The author is considered a Frenchman Paul Rox. Today, the program is used by millions of people and many enterprises 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. Inquiries in search engines confirm this, therefore many companies began to develop special programs. Today, there are many different programs that deal with data encryption. They use various cryptographic algorithms, the most famous ones are DES, AES, Brute Force and others.
Data encryption helps not only protect information, it also acts as a “squeezer”. Many archivers save disk space with encryption. For example, the well-known WinRAR uses the AES encryption algorithm with a key length of 128. Many users only store data on their computer in archived form, and each archive is password protected. This guarantees them not only more free space, but also the protection of important data from scammers.
With the development of the Internet, a well-trained hacker should not hack an unprotected computer and get the information he needs. Therefore, experts recommend encrypting all the data important to you.
