What is Encryption and Decryption?

In this world, the valuable information is our personal data. Nobody is going to share with others but sometimes it will take by hackers also, thus they can control our whole activities and easily earn money from us so that stopping these kinds of things technology introduced a new method for saving our data called Encryption and Decryption.

Frome above image you can easily understand. Now I am going to explain what image trying to tell

Consider the file have plain text(Important data) and I want to share with my friends so that I am encrypting my files. After encrypting, file Text will change to cipher Text.

(Note: whenever you going to encrypting you must have decrypting password )
Decrypting password will ask when you going to encrypting the files.

WITHOUT ENCRYPTING

Without encrypting, hackers can access and take our data so that they can threat and easily earn money from us

WITH ENCRYPTING

There are many methods using for encrypting our data even though consistently using some methods

• Public Key(Mostly this key using)
• Private Key()

Each and every person can have a unique public key and private key. If you are going to encrypt files with your public key at the same time can decrypt with your private key only.

Same as like  If you are going to encrypt files with your private key same time can decrypt with your public key only.

From above image, you can easily understand(Note: you never share your private key with others)

Hope this will help you lot. Please command if you don't understand.
