How does encryption protect data?

Encryption is a process in which a message or data is transformed in a confidential manner so that only its intended recipients can read it. In this process, the original message is converted into an indecipherable form by combining it with a special key (code). When this confidential message is sent to another person or system, it cannot be read or understood without a pre-determined key.

Types of data Encryption ?

There are two main types of encryption: symmetric and asymmetric. In symmetric encryption, the same key is used to transform the message into a confidential form. This means that the same key is used to convert the message into a confidential form and to read it. In asymmetric encryption, two different keys are used – one key to convert the message into a confidential form and the other key to read the message.

The use of encryption is very important from the point of view of security and privacy. This protects the data from unauthorized access and allows access only to those who have the correct keys. Without this, the security of confidential data may be at risk and may fall into the hands of unauthorized persons.
