Data encryption is the method of hiding the originalthe meaning of the document or message, which provides a distortion of its original appearance. 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 converted into an incomprehensible code for a stranger. The procedure itself depends on the sequence of changes in the type of data. Such a sequence is 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 solved and created.
Encryption methods were known in antiquity, when Roman commanders handed important letters with messengers in encrypted form. The algorithms were then primitive, but successfully entangled enemies.
Unlike those times we are not military leaders, but we have enemies. They are fraudsters who are eager to get important data for us. Here they also should be protected in any way.
USB flash drive today has become the most popular storage.information. Even huge corporations transmit important, confidential data on this kind of media. The demand for flash drives led scientists to the issue of data protection on them. For this purpose, programs have been invented that encrypt information on the media using a secret key known only to the real owner. Such data encryption on a flash drive is very reliable and will help protect important information from prying eyes.
The most popular data encryption programExperts believe TrueCrypt. It was created based on E4M (Encryption for the Masses), the first version of which was released back in 1997. The author is considered a Frenchman Paul Rocks. 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" any documents from prying eyes. Requests in search engines confirm this, so many companies have begun to develop special programs. Today, there are many different programs that are engaged in data encryption. They use various cryptographic algorithms, the most famous are DES, AES, Brute Force and others.
Data encryption helps not only protectinformation, it also acts as a “constrictor”. 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 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 the protection of important data from fraudsters.
With the development of the Internet well prepareda hacker is not worth the effort to hack an unprotected computer and get the information he needs. Therefore, experts recommend encrypting all the important data for you.
