Encryption️ Intermediate Quiz 3
1. Why is "MD5" no longer recommended for cryptographic security?
It is too slow to process modern data streams efficiently
It only functions correctly on legacy Linux distributions
It is vulnerable to collisions where different inputs share a hash
2. What is "HMAC" (Hash-based Message Authentication Code)?
A MAC type involving a cryptographic hash and a secret key
A compression method used for high-definition video files
A hardware tool used to monitor the temperature of a server
3. What is "SHA-3"?
A specific version of a browser designed for secure web access
The latest hash standard, based on the Keccak algorithm design
A specialized encryption protocol used for corporate email systems
4. What is a "Rainbow Table"?
A precomputed table used to reverse hashes for cracking passwords
A colorful list of administrative keys stored in a database file
A software tool used to organize and index large relational tables
5. What does the "Avalanche Effect" in hashing mean?
A sudden server crash caused by processing too much incoming data
A hash that grows longer in size as the original file becomes larger
A small input change causes a massive, unpredictable output change
6. Which algorithm is used for file integrity but is weak for security?
SHA-512
CRC32-X
BCRYPT
7. What is "bcrypt"?
A hashing function designed to be slow and expensive to compute
A secure method used to encrypt credit card numbers in a database
A fast indexing algorithm used to search for files on local drives
8. What is "Argon2"?
A noble gas used to cool high-performance servers in datacenters
A protocol designed for low-latency satellite communication links
A modern hashing standard highly resistant to GPU-based attacks
9. What is "Key Derivation Function" (KDF)?
A security script used to delete old encryption keys from a server
A function that derives secret keys from a master key or password
A master list used to keep track of all active keys within a system
10. What is "Pre-image Resistance"?
The difficulty of finding an original input given only its hash output
A mechanism that prevents image files from being encrypted by the OS
