What does ‘encryption’ primarily aim to achieve?

Encryption primarily aims to achieve data privacy and security. This process involves converting plaintext into cipher text, making it unreadable to unauthorized users or entities. By encrypting sensitive information, such as personal identification numbers, credit card details, or confidential communications, organizations can protect themselves against data breaches and cyber threats.

When encryption is implemented successfully, even if data is intercepted during transmission, it remains secure because it cannot be understood without the correct decryption key. This is essential in ensuring the confidentiality of data, which is vital in today's digital landscape where data privacy is a top concern for individuals and businesses alike.

Other options do not align with the primary function of encryption. For instance, error correction during transmission relates to ensuring data integrity rather than confidentiality. Similarly, while speed and enhanced network bandwidth are important aspects of networking, they are not direct objectives of encryption.
