File Checksum Monitoring

Help Center File trackingLast updated: 17 May, 2024

File Checksum Monitoring is a feature in that helps you keep track of changes to important files hosted online, such as zip files, PDFs, images, and more. It uses something called an SHA-256 checksum to see if a file has been altered. When a file changes, you'll get a notification, and the original file will be stored so you can review it.

What is SHA-256?

SHA-256 is a type of digital fingerprint for a file. Just like your fingerprint is unique to you, the SHA-256 checksum is unique to the file. If even a small part of the file changes, the SHA-256 checksum will change, too. This makes it easy to see if a file has been modified.

How It Works

  1. Setup: You provide the URLs of the files you want to monitor.
  2. Initial Check: calculates the initial SHA-256 checksum for each file and stores it.
  3. Regular Checks: regularly checks the files to see if their checksums have changed.
  4. Notifications: If a file's checksum changes, you get notified.
  5. File Storage: The original version of the file is saved so you can compare it with the new version.
