What does encryption primarily aim to achieve?

Encryption primarily aims to make information unreadable without a key, ensuring that only authorized users can access and interpret the data. This process transforms readable data, known as plaintext, into an encoded format, called ciphertext, which looks like a jumble of characters and is meaningless without the corresponding decryption key.

The main goal of encryption is to protect sensitive information from unauthorized access, thereby enhancing security and privacy. This is crucial in various contexts, such as protecting personal data, safeguarding communications, and securing financial transactions.

Other options do not align with the primary objective of encryption. For example, while data access speed and visibility might be important in data management, they are not the focus of encryption, which prioritizes confidentiality and integrity. Similarly, while encryption may facilitate secure data sharing between parties with the proper keys, the simplicity of data sharing is not an inherent goal of the encryption process itself.
