Understanding Hash Functions

What is the primary purpose of hash functions in a company's security strategy?

• To encrypt data

• To ensure data integrity and authenticity

• To compress data

• To increase data storage

What is a key characteristic of a hash function?

• It can be easily decrypted

• It produces a unique value for any input

• It increases the size of the data

• It requires a password to function

What is the process called when a plaintext document is converted into hashed text?

• Encryption

• Decryption

• Hashing

• Encoding

What was the original purpose of hash functions in computing?

• To encrypt sensitive information

• To quickly search for data

• To compress files

• To create digital signatures

What is a hash table?

• A type of encryption algorithm

• A data structure used to store key-value pairs

• A method for compressing data

• A tool for decrypting hash values

Which of the following is NOT a use of hash functions?

• Authentication

• Non-repudiation

• Data compression

• Data integrity verification

What does non-repudiation mean in the context of hash functions?

• The ability to deny the authenticity of information

• The inability to deny the authenticity of information

• The process of encrypting data

• The process of decrypting data

How do hash functions represent data of any size?

• As large, variable-size values

• As small, fixed-size values

• As encrypted text

• As compressed files

Which of the following best describes a hashing algorithm?

• A reversible process

• A one-way function

• A data compression tool

• A decryption method

Why can't hash codes be decrypted?

• Because they are encrypted with a key

• Because they are designed to be irreversible

• Because they are stored in a secure database

• Because they are too complex
