Who is Kevin Mitnick:Kevin David Mitnick is an American computer hacker and computer security consultant.

The other key which can be used for any type of message as anything in general is called public key. The private key is used to encrypt messages personally and will not be seen or shared by any other user. While the public key is again used for the same reason as encryption, but it is hidden from others except ourselves. Data encryption via public key can also be decrypted via private key.
