Explain the difference between asymmetric and symmetric encryption.

There are four main differences between symmetric and asymmetric encryption.

Explanation:

Encryption is the process of locking up information using cryptography; it means that the information locked in that way is encrypted. There are two types of encryption: symmetric and asymmetric encryption; they have four main differences. First of all, symmetric encryption uses a single key that needs to be shared among the people who need to receive the message; however, asymmetric encryption uses a pair of public key and a private key to encrypt and decrypt messages. Another difference is that symmetric encryption is an old technique, while asymmetric encryption is new. The third difference is that asymmetric encryption was introduced to solve problems of symmetric encryption (eliminated the need to share the key). Lastly, the fourth difference is that asymmetric encryption takes more time than de symmetric one.
