Fundamentals of Secure Software - Hashing Demo

The video tutorial demonstrates how to generate and verify hashes using OnlineMD5 and PowerShell. It explains the importance of hash consistency for file verification, using the example of a Linux Mint ISO file. The tutorial shows how to use OnlineMD5 for string input and file hashing, and how to use PowerShell's certutil command to generate and compare hashes, ensuring file integrity.

What happens to the hash value when a single character is added to the input string?

• The hash value changes drastically.

• The hash value changes slightly.

• The hash value remains the same.

• The hash value becomes zero.

Why might you want to verify the hash of a downloaded file?

• To verify the file's download speed.

• To check the file's size.

• To confirm the file's integrity and that it hasn't been tampered with.

• To ensure the file is the latest version.

What tool is used in PowerShell to generate a hash for a file?

• hashgen

• certutil

• filehash

• hashcheck

What is the purpose of comparing hash values of a file?

• To calculate the file's size.

• To find the file's location.

• To ensure the file's content is unchanged.

• To determine the file's type.

Which hash algorithm is NOT mentioned in the tutorial?

• SHA-256

• MD5

• SHA-1

• SHA-512
