Ceaser Cipher, Atbash Cipher, and Rot13 cipher

Calculate the result of applying a Caesar Cipher with a shift of 3 to the word "HELLO".

• KHOOR

• JEPPS

• KHOORZ

• KHOORX

Analyze why the Atbash Cipher is not suitable for modern encryption needs.

• It is easily deciphered due to its simplicity.

• It uses complex algorithms that are hard to break.

• It requires a key that is difficult to manage.

• It is based on random number generation.

What is the result of applying the Rot13 cipher to the word "HELLO"?

• URYYB

• URYYA

• HELLO

• EBBYY

What is the primary function of a Caesar Cipher?

• To encrypt data by shifting letters a fixed number of places

• To decode messages using a key

• To create random passwords

• To compress data for storage

Which of the following best describes the Atbash Cipher?

• A cipher that shifts letters by a fixed number

• A cipher that substitutes each letter with its opposite in the alphabet

• A cipher that uses a keyword for encryption

• A cipher that uses numbers to represent letters

Explain the historical significance of the Caesar Cipher.

• It was used by Julius Caesar to communicate with his generals.

• It was the first cipher ever created in history.

• It was used by the Romans to encrypt military strategies.

• It was developed during the Renaissance period for secretive communication.

What is a practical use of the Atbash Cipher in modern times?

• Creating simple puzzles and games

• Encrypting sensitive data

• Securing online transactions

• Generating random passwords

Discuss the limitations of using a Caesar Cipher for secure communication.

• It is easily broken with frequency analysis.

• It provides perfect secrecy.

• It requires a complex key exchange.

• It is immune to brute-force attacks.

How does the Rot13 cipher differ from the Caesar Cipher?

• Rot13 shifts letters by 13 places, while Caesar can use any shift.

• Rot13 is a type of Caesar cipher with a shift of 3.

• Both ciphers shift letters by the same number of places.

• Rot13 only works with uppercase letters, while Caesar works with both.

Describe a scenario where the Rot13 cipher might be used today.

• Encoding spoilers or jokes in online forums

• Encrypting sensitive government documents

• Securing online banking transactions

• Hiding personal information in social media posts
