15 Cryptography and Code Breaking Trivia Questions and Answers

1. Question: What is cryptography?
   Answer: Cryptography is the practice and study of techniques for securing communication and data from unauthorized access.
2. Question: Who is known as the “father of modern cryptography”?
   Answer: Claude Shannon
3. Question: What was the Enigma machine used for during World War II?
   Answer: The Enigma machine was used by the Germans to encrypt military communications during World War II.
4. Question: Which British mathematician and cryptanalyst is famous for breaking the Enigma code?
   Answer: Alan Turing
5. Question: What is the difference between symmetric and asymmetric encryption?
   Answer: Symmetric encryption uses the same key for both encryption and decryption, while asymmetric encryption uses a pair of keys (public and private) for encryption and decryption.
6. Question: What is a Caesar cipher?
   Answer: A Caesar cipher is a substitution cipher in which each letter in the plaintext is shifted a certain number of places down the alphabet.
7. Question: What does the acronym RSA stand for in cryptography?
   Answer: RSA stands for Rivest-Shamir-Adleman, the surnames of the algorithm’s inventors.
8. Question: What is a one-time pad and why is it considered secure?
   Answer: A one-time pad is an encryption technique that uses a random key that is as long as the message itself and is used only once, making it theoretically unbreakable if used correctly.
9. Question: What is steganography?
   Answer: Steganography is the practice of hiding messages or information within other non-secret text or data.
10. Question: What is a hash function in cryptography?
    Answer: A hash function is a function that converts an input (or ‘message’) into a fixed-size string of bytes, typically a hash value, which appears to be random.
11. Question: Who invented the Data Encryption Standard (DES)?
    Answer: The Data Encryption Standard (DES) was developed by IBM and adopted by the National Institute of Standards and Technology (NIST).
12. Question: What is the purpose of a digital signature?
    Answer: A digital signature is used to verify the authenticity and integrity of a message, software, or digital document.
13. Question: What does the term “public key infrastructure” (PKI) refer to?
    Answer: Public key infrastructure (PKI) refers to the set of hardware, software, policies, and standards needed to manage digital certificates and public-key encryption.
14. Question: What is quantum cryptography?
    Answer: Quantum cryptography is a type of cryptography that uses principles of quantum mechanics to secure data, making it potentially immune to quantum computer-based attacks.
15. Question: What historical document is known as one of the earliest uses of cryptography in written form?
    Answer: The “Caesar Cipher” used by Julius Caesar is one of the earliest known uses of cryptography in written form.
