Problem Statement
What is the main purpose of encryption?
Explanation
Encryption protects sensitive information by converting it into a coded format that cannot be understood without the correct key.
For example, when you send data over the internet, encryption ensures that even if someone intercepts it, they cannot read or modify it. Only the recipient with the decryption key can access the original information.
Modern encryption standards such as AES and RSA are essential for secure online transactions, cloud storage, and communication systems.
