This is an article about a malicious program, which is called Cryp1. It is a virus that enters a person's computer, encrypts every one of the files that it could, and requirements a ransom for decryption. Such viruses are classified as ransomware, and they are considered probably the most dangerous varieties of viruses. Their danger is in the belief that they pursue a certain goal so when desire to is achieved - an individual is a a disadvantage: the guy can either accept give the money, or lose his data, which can be very valuable. Cryp1 virus encrypts files with all the RSA algorithm. This algorithm is one of probably the most complex on the planet, and it is used not only by hackers, but additionally through the governments and also the military forces of several countries, such as United States. The code is indeed complex, that it is difficult to crack it with no key. More precisely, it will be possible, but requires enormously powerful computer plus an immense period of time. Of course, a normal user can?t decrypt your data, and, frequently decides to cover a ransom.
