What is encryption?

Encryption is the process of making data unreadable to unauthorized users. This is achieved through algorithms that convert the original data, known as plaintext, into a scrambled format called ciphertext. Only those with the appropriate decryption key can revert the ciphertext back into its original form, thereby ensuring that sensitive information is protected from unauthorized access.

The significance of encryption lies in its role in securing communications, protecting personal and financial information, and maintaining privacy in various applications—from online transactions to storing confidential data. By transforming data into an unreadable format, encryption helps to safeguard against data breaches and cyber threats, ensuring that only authorized parties can access and understand the information.

In contrast, the other options address unrelated processes. Organizing data pertains to data management practices, storing data in the cloud refers to using online storage solutions without necessarily involving security measures like encryption, and analyzing data focuses on interpreting and finding insights within data rather than protecting it.
