Explanation:

: Talk about asymmetric encryption is the same as talk about Public / Private key encryption, in
this method of encryption we use 2 keys, one to encrypt the data, and another to decrypt it. In this
model of encryption, the users have a public and a private key, the public key is of free distribution
and is usually published in a directory, while the private keys must be keep secure. This kind of
encryption is like a thousand times slower than symmetric one. Asymmetric encryption usually use
certificates to validate the key.
