Encryption is a method of converting readable data into an encoded format using algorithms. Only those with the appropriate decryption key can convert the data back into its original, usable form. It is a primary method for protecting data confidentiality in storage and transmission.
Distraction (A), Disgruntling (B), and Falsification (C) are unrelated to data protection techniques.
