Answer 1

The correct answer is Cryptography is for masking message content; Steganography is for hiding the existence of the message itself.

Key Points

Cryptography involves techniques used to secure communication in the presence of third parties by transforming the message into an unreadable format, known as encryption.
The primary goal of cryptography is to ensure confidentiality, integrity, authenticity, and non-repudiation of the message.
Steganography is the practice of concealing a message, image, or file within another message, image, or file so that the presence of the hidden message is not detected.
The main purpose of steganography is to hide the existence of the communication, rather than the content itself.
Both cryptography and steganography are used for information security, but they serve different purposes.

Additional Information

Option A: Cryptography is for translation; Steganography is for dictation
- This statement is incorrect. Cryptography is not about translation but about securing message content through techniques like encryption.
- Steganography is not about dictation but about concealing the existence of messages.
Option B: Cryptography is for masking message content; Steganography is for dictation
- This statement is partially correct but incorrect regarding steganography. While cryptography does mask the message content, steganography is not related to dictation but to hiding the existence of the message.
Option C: Cryptography is for masking message content; Steganography is for hiding the existence of the message itself
- This statement is correct.
- Cryptography focuses on transforming the message so that it is unreadable without the proper decryption key.
- Steganography aims to make the message itself undetectable by embedding it within another medium.
