Correct option is B
Encryption is the process of converting plain text into a secure, unreadable format (cipher text) to ensure the confidentiality of data. It is widely used for secure communication and data protection.
Important Key Points:
1. Encryption uses algorithms like AES, RSA, and DES for secure data transformation.
2. It is a critical component in ensuring data privacy and integrity.
3. Encrypted data can only be accessed by users with the correct decryption key.
Knowledge Booster:
• Decryption: The process of converting encrypted data back into its original readable form.
• Hacking: Unauthorized access to data or systems, which encryption aims to prevent.
• Encoding: Converts data into a specific format for transmission, but it is not secure.
• Compression: Reduces the size of data without focusing on security.
