LAB 1: How to Compare Hashes

This video tutorial explains the importance of file hashes and checksums in ensuring data integrity during file downloads. It covers the process of generating and verifying checksums using hashing algorithms like MD5 and SHA. A practical exercise demonstrates how to verify a downloaded file's integrity using PowerShell commands, ensuring the file is correct and uncorrupted.

Why are checksums important in file downloads?

• They increase the download speed.

• They help in verifying data integrity.

• They encrypt the file content.

• They reduce the file size.

Which of the following is a common hashing algorithm used for generating checksums?

• DES

• MD5

• RSA

• AES

What is the first step in verifying a downloaded file's integrity?

• Comparing file sizes

• Generating a local hash

• Checking the file extension

• Opening the file

In the practical example, which command is used in PowerShell to generate a file hash?

• Verify-File

• Generate-Hash

• Create-Checksum

• Get-FileHash

What indicates that a downloaded file is correct after comparing hash values?

• The file size is larger.

• The file opens without errors.

• The download speed was fast.

• The hash values match.
