Most of the times when we talk about crypto, we refer to the cryptocurrencies as an abbreviation. However, originally relates to cryptography. Few know that this is one of the methods of cyber security more efficient today. This time we will discuss the reason.

What is it?
In fact, while it is a method of cyber-security, what crypto is born in parallel with the same spelling. What we see in the definition that the Royal Spanish Academy provides in this regard: “the Art of writing with a secret key or in an enigmatic manner” The reason for this is because the crypto in practical terms, is a form of writing in secret code, which can only be decrypted by the that know the code. When considering this, people throughout history have been seeking to adapt this form of protection in your information. A famous example is the case of Da Vinci, who wrote as if it were a mirror, so that only those who knew the technique to reflect his writings could be read. With the arrival of the digital age, what crypto has evolved to be more sophisticated and efficient. In this way were born the platforms that encrypt the information.
Procedure
The way that these crypto platforms work is by means of the emission and reception of signals. First noting that all the information that handled the applications are then sent as signals, which are received by a receiver. What crypto does is to transcribe these signals so that they have a secret code. The way that works is that the platform has a unique algorithm that encrypts the information, which can only be read by a platform with the same algorithm.
Key examples
There are two key examples to understand how it works, what crypto, starting with the famous VPN. YouTube is a famous application known as NordVPN, which we will use as an example. The way it works is that when you activate it on the device, all emitted signal is transformed into a secret code. Therefore, if a person fails to catch the signal emitted by the device, will not be able to understand the information that it stores. The importance of having this cyber-security is that in the public networks, all the things, such as pictures or passwords, is accessible to the people. So, what crypto is essential for these cases. It should be noted that there are applications that include the crypto by default without the need of a VPN, as some banks around the world. The second application is famous in cyber security are the Two-Step, the verification processes in some applications. A famous example is Google Authenticator, the security app from Google. The way it works is asking for a code generated by the same algorithm that applies the crypto operations. In this way, that code works like a key, secret and unique, impossible to decipher by an outsider. Even different pages that work with cryptocurrencies recommend to use this application, as Binance or LocalBitcoins. The following two tabs change content below. I am a student of economics, interested in innovation and technological development, always faithful to that tomorrow will be a better day.
