In symmetric encryption the same key is used to encrypt and decrypt a message. in asymmetric encryption different keys are used to encrypt and decrypt. give at least one reason why asymmetric encryption is useful

Encryption is the process of securing the data or information by storing and even transmitting data with advanced principles of mathematics. in asymmetric encryption there is a concept of public key that is made available to anyone who wants the access and is passed over the internet and a private key which attained by just one person. One reason asymmetric encryption is useful because it is more secure because the ownership of the secure private key is held always with one person and the public key is shared to the associated ones.

A useful advantage of Asymmetric encryption over symmetric encryption is that there is no secret channel necessary for the exchange of the public key, unlike in the symmetric encryption which requires a secret channel to send the secret key.

Another advantage of Asymmetric encryption is that is has increased security. Asymmetric uses two different keys (Public and private) for both encryption and decryption of data while symmetric uses one.
