Encrypting a file or other information stored in a computer means converting it into a secret code and it can’t be used or understood until it is decoded or decrypted. you might want to encrypt the files that contained a secret formula for a new invention, or some financial plans that your competitors would love to know about them in advance. When you encrypt something then the computer asks you to create a password. After that, no one will be able to know about the information unless they have the same password. Encryption hides your data from unauthorized third-party users. This is the process of encoding data which prevents the data from viewing or modifying by an unauthorized person.
