Encryption secures information by converting readable data (plaintext) into an unreadable format (ciphertext) so that only someone with the proper decryption key can return it to its original form. This protects confidentiality and prevents unauthorized access. The other choices describe performance, backup, or sharing functions, which are not the main purpose of encryption.
