Checking the SHA256 checksum on Windows 10 is like verifying a secret code. It ensures the file you downloaded is exactly what it claims to be, free from tampering. To do this, you’ll use a tool called Command Prompt. First, find the checksum value on the website where you downloaded the file. Then, use a command to generate the checksum of your downloaded file and compare the two. It’s quick and ensures your file’s integrity and authenticity.
How to Check SHA256 Checksum Windows 10
To verify the integrity of a file using the SHA256 checksum on Windows 10, follow these steps. This process helps you confirm that the file hasn’t been altered or corrupted during download.
Step 1: Open Command Prompt
Press the Windows key, type “cmd,” and hit Enter.
Command Prompt is your gateway to running system commands. It might look intimidating, but it’s just a text-based interface where you can type commands to perform tasks.
Step 2: Navigate to File Location
In Command Prompt, type cd followed by the folder path where your file is located. Press Enter.
Navigating to the correct folder ensures you’re checking the right file. If your file is in the “Downloads” folder, you might type something like cd C:UsersYourNameDownloads.
Step 3: Run SHA256 Command
Type certutil -hashfile filename SHA256 and press Enter. Replace “filename” with your file’s name, including its extension.
This command tells your computer to calculate the SHA256 hash of your file. It’s like asking your computer to take a digital fingerprint of the file.
Step 4: Compare the Output
Look at the long string of numbers and letters. Compare it with the checksum provided on the website.
The string that appears is your file’s SHA256 checksum. If it matches the one from the website, your file is legit and safe.
Step 5: Confirm Match
Make sure both checksums are identical.
If they match, congratulations! Your file is authentic. If not, you might need to download it again.
After completing these steps, you’ll have peace of mind knowing your file hasn’t been tampered with and is exactly what the developer intended.
Tips for How to Check SHA256 Checksum Windows 10
- Always download files from reputable sources to ensure the checksum provided is trustworthy.
- Use copy-paste for the checksum values to avoid errors when comparing strings.
- If the checksum doesn’t match, try downloading the file again before assuming it’s malicious.
- Learn basic command prompt navigation to speed up the process.
- Keep your system updated to ensure all tools, including Command Prompt, are functioning correctly.
