Practical Cyber Hacking Skills for Beginners - Calculating Hash Values with PowerShell

The video tutorial introduces Microsoft PowerShell, an open-source tool available for Windows, Mac, and Linux. It guides viewers through downloading and setting up PowerShell, organizing files, and using PowerShell commands to calculate hash values for different file types. The tutorial explains hash collisions, comparing MD5 and SHA256 algorithms, and demonstrates the practical application of hashing for file integrity verification.

Which operating systems support Microsoft PowerShell?

• Only Linux

• Windows, Mac, and Linux

• Windows and Mac

• Only Windows

What is the first step in setting up PowerShell for hash value calculation?

• Create a folder named 'PowerShell'

• Download a specific file format

• Run a specific command

• Install a specific software

Which command is used to calculate hash values in PowerShell?

• get-filehash

• calculate-hash

• hash-calculate

• file-hash

What is the default hashing algorithm used by PowerShell?

• MD5

• SHA-1

• SHA-512

• SHA-256

How can you change the hashing algorithm to MD5 in PowerShell?

• Use the command 'set-algorithm MD5'

• Add '-Algorithm MD5' to the command

• Change settings in PowerShell

• Use a different software

What is a hash collision?

• When two files have different hash values

• When two files have the same hash value

• When a file cannot be hashed

• When a file is corrupted

Why is SHA-256 preferred over MD5?

• SHA-256 is faster

• SHA-256 is more secure

• SHA-256 is easier to use

• SHA-256 is less complex

What happens to the hash value if a file is slightly modified?

• The hash value changes slightly

• The hash value changes completely

• The file cannot be hashed again

• The hash value remains the same

What is the purpose of calculating hash values for files?

• To compress files

• To encrypt files

• To verify file integrity

• To improve file performance

How can you verify the integrity of a file sent to a friend?

• By checking the file size

• By comparing hash values

• By opening the file

• By renaming the file
