Dongle is a commonly used item in computer security, so what exactly is a dongle?

1. When your computer is threatened by security, you generally need to use a dongle for protection. However, many friends do not know what a dongle is. I will tell you next.

2. A dongle is actually an encryption lock. It is an encryption product that combines software and hardware and is plugged into the parallel port of a computer. The encryption lock has a strong software protection function and is designed to prevent intellectual property rights from being illegally used.

3. The security factor of the dongle is very high, it has the ability to judge and analyze, and it also has enhanced active anti-decryption capabilities. Therefore, if the software that needs to be protected is written into the microcontroller, it is guaranteed that the encryption lock hardware cannot be copied.

4. However, with the continuous development of decryption technology, the single-chip dongle algorithm is too simple, and the storage space is very small, and it is easy to be copied by hardware, so it is gradually eliminated. The latest "smart card" dongles are on the rise.

The above is the explanation of what the dongle is that the editor has compiled for you. If you need to improve the dongle, hurry up and buy it.
