Encryption and Decryption - Overview

Encrypting and decrypting data are crucial steps to safeguard sensitive information during transmission.

Encryption transforms data into a secure, unreadable format using algorithms such as AES (Advanced Encryption Standard). This ensures that only authorized parties with the appropriate decryption key can access the original data.

Decryption reverses this transformation, restoring the data to its original form so it can be read and used as intended. These processes ensure the confidentiality and integrity of the data throughout its journey.

To better understand these processes, the following flow diagram illustrates the general steps involved in both encryption and decryption.
