The procedure of creating information unreadable by computers or other people with the objective from getting use of its contents of avoiding others.

Protected data is produced utilizing an encryption system for example perhaps a basic encryption key, security device, or PGP and seems as trash until it’s decrypted.

Utilize or to be able to study the information, it should be decrypted, and just those individuals who have decryption key or the right code can create the data readable.

Encryption is also used to protect data in transit, for example data being transferred via networks (e.g. the Internet, e-commerce), mobile telephones, wireless microphones, wireless intercom systems, Bluetooth devices and bank automatic teller machines. There have been numerous reports of data in transit being intercepted in recent years.[15] Data should also be encrypted when transmitted across networks in order to protect against eavesdropping of network traffic by unauthorized users.
