When using platforms and/or consuming their services, it is common to come across messages that our information is being encrypted. Most companies adopt the practice of encryption on their digital platforms – where customer data is collected. After all, what is encryption, who has access to it and how does it work?
Cryptography, in short, is a set of techniques and protocol structures to be used to prevent “third parties” – people not involved in the conversation and unwanted – from having access to a private message. The word “crypto”, in Greek, means “secret”
How did data encryption come about?
Historically, encryption is not something exclusive to the internet, although its technical development has been intensified by software email data in digital security. The encryption format has been recognized since the Second World War. At the time, the German “Enigma” machine was created, which was used to encrypt and decrypt war codes throughout Europe.
Even though they are in different times, the goal is the same: to keep information safe. For digital security , having a data encryption system is having as an ally a mechanism that always seeks to eliminate the chances of any third party having access to the data. It is done through a data conversion, which goes from a readable format to an encrypted one. Once encrypted, they can only be readable again when they go through the opposite process, decryption.
Cryptography and Cryptocurrency
It is important to highlight the role of revolutionizing small businesses in digital media, as well as data encryption. One example is cryptocurrency. Cryptography, as the name suggests, is also used in cryptocurrencies, the so-called digital currencies, to ensure that transfers occur securely, without fraud or risks of cyberattacks. Bitcoin, for example, uses a technology involving public and private keys.
Common means of encryption:
Symmetric key : Symmetric b2b reviews uses a single private key. Which is between the sender (the person sending the message) and the recipient of the content, the person receiving the encrypted message. The same key is used to encode and decode. The method is performed more quickly. However, with the sharing of the symmetric key, in a unique way, there is a greater risk compared to the asymmetric encryption key, as is the case with Bitcoin.
