# Quiz 8

**Let's apply what you have learned so far to a specific scenario. Choose the correct response.**

You have downloaded a software installation file from a trusted website. To ensure the file has not been tampered with, the website provides a SHA-256 checksum for verification. What steps should you take to confirm the file's integrity?

**Type all answers and select the correct one**

* [x] Use a SHA-256 hashing tool to generate the hash value of the downloaded file and compare it with the checksum provided on the website.
* [ ] Open the file and check its properties to see if it matches the checksum.
* [ ] Use any hashing algorithm (e.g., MD5) to generate a hash value and compare it with the provided SHA-256 checksum.
* [ ] Skip the verification process since the file was downloaded from a trusted source.<br>

**Note to learners**

To ensure the file's integrity, you must use the same hashing algorithm (in this case, SHA-256) to generate a hash value for the downloaded file. Then, compare the generated hash with the checksum provided on the website. If they match, the file has not been tampered with. Using a different hashing algorithm or skipping the verification process would not ensure the file's safety.
