Questions and Answers

What is the primary purpose of a hash function in cryptography?

  • To generate random numbers for cryptographic operations
  • To encrypt data for secure transmission
  • To compress data for efficient storage
  • To map data of arbitrary size to fixed-size values (correct)

    • What does a hash function produce as output?

  • Fixed-size result called a hash value (correct)
  • Encrypted message
  • Random set of characters
  • Variable-length block of data

    • What property should a 'good' hash function have?

  • Always generate the same output for a given input
  • Produce outputs that are evenly distributed and apparently random (correct)
  • Produce outputs that are predictable
  • Have a variable-size result

    • What is the hash value also known as?
