She write her message in a box and lock her message by using the padlock and send it. Now this message is encrypted and at the other side the shiny receive the message and open it from the key that he already have and this key is identical to cristina&#8217;s key. Shiny got this key before sometime from any physical medium. So shiny applied this key which is identical and read the message. Also shiny can send the reply of this message from his padlock.<\/p>\n\n\n\n<p>There are two parts of this encryption algorithm<\/p>\n\n\n\n<p>stream ciphers<\/p>\n\n\n\n<p>Block ciphers<\/p>\n\n\n\n<p>stream ciphers encrypt the bit of the message at a time while block ciphers as its name indicates it encrypt the message bits in the blocks.<\/p>\n\n\n\n<p><strong>(2) Asymmetric Algorithm<\/strong><\/p>\n\n\n\n<p>There are two different keys are available in the asymmetric algorithm.

The shiny send his open padlock and cristina receive it then she type her secret message in it then she lock is by using her public key. Then she send the message that is encrypted to the shiny. The shiny use his private key and read the message.<\/p>\n\n\n\n<p>The advantage of asymmetric algorithm is that we do not need to share our private key on the network so your key is safe.
