Translations:Checksums als middel om de integriteit van bestanden te bewaken/11/en

There are lots of – free – software packages available for MD5 checksums. The principle is always the same and equally simple: the software creates checksums for a number of files, resulting in a small text file that you store together with the files. To verify the files, the software compares the new checksum against the one in the text file. So, if you want to ensure that data is not lost because a carrier deteriorates – causing it to lose the file – you need to save the small text file in a different location, e.g. an external hard drive.
