How to Check SHA256 Checksum on Windows 10
Checking the SHA256 checksum on Windows 10 is like verifying the authenticity of a digital handshake. It ensures the file you downloaded hasn’t been tampered with. To do this, open Command Prompt, type in a specific command followed by the file path, and press Enter. The system will generate a checksum that you can compare to the original.
Step-by-Step Tutorial: How to Check SHA256 Checksum on Windows 10
In this section, you’ll learn how to check a file’s SHA256 checksum using Command Prompt. These steps will guide you through the process quickly and easily.
Step 1: Open Command Prompt
Press the Windows key, type "cmd," and hit Enter.
Opening Command Prompt is your gateway to inputting commands directly into your computer. It’s a straightforward tool that allows for various operations, including verifying checksums.
Step 2: Navigate to the File Location
Use the ‘cd’ command to go to the directory where the file is stored.
Navigating to the correct directory is crucial. Without this step, the system won’t know where to look for the file you’re verifying. Use ‘cd’ followed by the folder path.
Step 3: Enter the Checksum Command
Type "certutil -hashfile [filename] SHA256" and press Enter.
This command tells Windows to calculate the SHA256 checksum of your specified file. Replace [filename] with your actual file name, including its extension. Make sure the file name is correct to avoid errors.
Step 4: Compare the Checksum
Match the generated checksum with the original provided by the file source.
After running the command, you’ll get a string of numbers and letters. Compare this with the original checksum from the source. They should match perfectly. If not, the file might be corrupted or altered.
Step 5: Verify the Results
Ensure the checksums match to confirm file integrity.
If both checksums are identical, the file is authentic and safe to use. If they don’t, consider re-downloading the file from a trusted source.
After completing these steps, you’ll know whether your file is genuine or tampered with. If the checksums match, it means the file’s integrity is intact, and you can proceed with using it confidently.
Tips for Checking SHA256 Checksum on Windows 10
- Always download files from reputable sources to minimize risks.
- Double-check the file name and path to avoid errors in the command.
- Save commonly used commands in a text file for quick access.
- If the checksum doesn’t match, try downloading the file again.
- Regularly update your system to ensure all tools work correctly.
Frequently Asked Questions
What is a checksum?
A checksum is a digital fingerprint of a file. It verifies that the file hasn’t been altered during download or transfer.
