What do encryption and decryption processes accomplish?

The encryption and decryption processes primarily serve to secure data by converting it into an unreadable format, which is accomplished through encryption, and then converting it back into a readable format through decryption. When data is encrypted, it is transformed using algorithms and cryptographic keys, rendering it inaccessible to unauthorized users even if they gain physical access to the data. This process ensures that sensitive information, such as financial records or personal information, remains confidential and protected from unauthorized access during storage or transmission.

In practical terms, any data that is intended to be kept secure, whether it's a message, a file, or even data in transit across networks, can be protected through these processes. The ability to reverse this transformation through decryption ensures that only authorized users, who possess the correct keys or credentials, can access the original, understandable data.

The other aspects mentioned, such as data processing speed, readability, or facilitating data sharing, are secondary implications or outcomes of secure data practices, but they are not the primary purpose of encryption and decryption.
