What is data encryption?

In the digital world, encryption is the conversion of data from a readable format to an encrypted format that can only be read or processed after decryption.

Encryption is the basic building block of data security and the simplest and most important way to ensure that information in the computer system cannot be stolen and read by someone who wants to use it for malicious purposes.

Used by both individual users and large corporations, encryption is widely used on the Internet to ensure the inviolability of user information transmitted between a browser and a server.

This information may include any type of information, from payment data to personal information. Companies of all sizes generally use encryption to protect sensitive data on their servers and databases.

The need for encryption

Beyond the obvious utility of protecting private information against theft or threat, encryption also makes it possible to prove that the information is authentic and from the source from which it claims to come. It can be used to check the origin of a message and to confirm that it has not been modified during transmission.

The key to the door

The principles of encryption are based on the notion of encryption algorithms and “keys”. When the information is sent, it is encrypted using an algorithm and can only be decrypted using the appropriate key. A key can be stored on the receiving system, or can be transmitted with the encrypted data.

Methods of operation

Several methods are used to code and decode information. These methods are developing in parallel with the constant evolution of computer software and methods for intercepting and stealing information. Here are some of these methods:

– Symmetric Encryption Key: Also known as a secret key algorithm, it is a unique decoding method that must be provided to the recipient before the message can be decrypted. The key used to encode is the same as the one used to decode, which is perfectly suitable for individual users and closed systems. Otherwise, the key must be sent to the recipient, which increases the risk of compromise if it is intercepted by a third party (a hacker for example). The advantage of this method is that it is much faster than the asymmetric method.

– Asymmetric cryptography: this method uses two different keys (public and private) mathematically linked. In practice, keys consist only of large numbers that have been coupled together but are not identical, hence the asymmetric term. The public key can be shared with everyone, but the private key must remain secret. Both can be used to encrypt a message, and the key opposite to the one originally used to encrypt that message is then used to decrypt it.
