Checking a SHA256 checksum on Windows 10 is a straightforward process that ensures the integrity and authenticity of your files. The SHA256 algorithm generates a unique hash for each file, allowing you to verify whether a file has been altered. All you need is your Command Prompt and the file you want to check. By running a simple command, you can compare the hash of your downloaded file against the one provided by the source to confirm everything’s intact. Now, let’s dive into the details and learn how to check SHA256 checksum on Windows 10.
How to Check SHA256 Checksum on Windows 10
Checking the SHA256 checksum of a file on Windows 10 is a quick and simple process. By following these steps, you’ll be able to verify the integrity of any file you download.
Step 1: Open Command Prompt
To start, you’ll need to open Command Prompt on your Windows 10 computer.
You can do this by typing “cmd” into the search bar on the taskbar and hitting Enter. This will open a black window where you can type commands.
Step 2: Navigate to the File Location
Once the Command Prompt is open, use it to navigate to the folder containing the file you want to check.
This involves using the “cd” command followed by the directory path. For example, if your file is in the Downloads folder, you would type “cd Downloads” and press Enter.
Step 3: Use the CertUtil Command
Now it’s time to generate the SHA256 checksum. Type “certutil -hashfile filename SHA256” replacing “filename” with your actual file name, and hit Enter.
This command asks Windows to calculate the hash of the specified file using the SHA256 algorithm. If you’re unsure of the file name, you can type the first few letters and press Tab to auto-complete it.
Step 4: Verify the Checksum
Compare the output from the Command Prompt with the official checksum provided by the file’s source.
This is your moment of truth. If the two checksums match, your file is exactly as it should be. If not, there might be an issue, and downloading the file again is advisable.
Step 5: Close Command Prompt
Once you’ve verified your file’s integrity, you can safely close Command Prompt.
Simply type “exit” and press Enter, or click the “X” button in the top right corner to close the window.
After completing these steps, you’ll have peace of mind knowing your file hasn’t been tampered with.
Tips for Checking SHA256 Checksum on Windows 10
- Always ensure you download files from trusted sources to minimize the risk of corrupted or malicious files.
- Keep a list of common directories handy to quickly navigate in Command Prompt.
- Familiarize yourself with other hash types like SHA1 and MD5 for broader verification skills.
- Use an auto-complete feature by pressing Tab to avoid typing errors in file names.
- Double-check the checksum value from a reliable source before comparing it to your generated hash.
Frequently Asked Questions
What is a SHA256 checksum?
A SHA256 checksum is a hash value generated by the SHA256 algorithm, used to verify a file’s integrity.
Why should I check SHA256 checksums?
Checking the checksum ensures your file hasn’t been altered, which is crucial for security and reliability.
