Calculate the downloaded image's checksum. This will take a while!
By calculating the image's `checksum` on your own computer and comparing it to the original `checksum`, you can verify the image has not been tampered with or corrupted. The original checksum values are provided at link:++[], and are [command]#gpg# signed to demonstrate their integrity.
Because transmission errors or other problems may corrupt the Fedora image you have downloaded, it is important to verify the file's integrity. After the images are created, an operation is performed on the file that produces a value called a `checksum` using a complex mathematical algorithm. The operation is sufficiently complex that *any change* to the original file will produce a different checksum.
