How to verify downloaded files?
There are two ways to check the files you've downloaded:
- using their checksum,
- using their digital signature.
The checksum lets you check that the file was not corrupted during the transfer from the server to your machine. The digital signature lets you check that the file was created by the project maintainer and not altered since then.
Using the checksum
The checksum is a short sequence of letters and numbers obtained by using the MD5 hashing algorithm on a file.
You can use that sequence, called the MD5 sum, to check that the file has arrived on your machine intact.
- Download the checksum file to the same directory where you've downloaded the project file you want to verify.
- Open a terminal, change to the directory where you have saved the file and accompanying
checksum, then enter the following:
$ md5sum -c checksumfilenameReplace checksumfilename with the checksum filename. Obviously you need to replace filename with the name of the file you downloaded.
- You'll see a line saying whether file integrity is fine or not.
filename: FAILEDIf the checksum does not match, do not use the downloaded file. Try to download it again. If it fails again, tell so on the project mailing list.
md5sum: WARNING: 1 computed checksum did NOT match
