Encryption
What is Encryption-
Encryption is a conversion of data into another form called ciphertext which is not understandable by anyone easily except authorized person.
Why we need Encryption
We need encryption because - our personal data (accounting information, personal pictures,documents) and confidential information is needed to be secure. There is a mechanism which is provided by the encryption to secure our data and information by converting them to another form.
How Encryption Works
There are many algorithm works behind the Encryption .The basic idea behind Encryption is to convert plaintext(i.e easily understandable form )to ciphertext.
For example Hello is a plaintext that can be changed into ciphertext like gfmmp by shifting index of alphabet that is called Caesar cipher.
