![]() The other tools mentioned work similarly. If the generated checksum matches the one provided on the Ubuntu MATE download page, that will mean no data was changed while you downloaded the file – in other words, your downloaded file is not corrupted. Generating SHA-256 Checksum for Ubuntu MATE iso Let’s see how to verify a checksum on Linux. Secure Hash Algorithms and variants ( SHA-1, SHA-2 etc.).The most popular checksum algorithms are: There are various algorithms for generating checksums. Without going into the technical details let’s just say it takes a file as input and outputs the checksum value of that file. How is a Checksum generated?Įach checksum is generated by a checksum algorithm. We will use an Ubuntu MATE “ ” image file for this guide. If it doesn’t, that means your downloaded image’s integrity is compromised (maybe it was corrupted during the download process). So after you’ve downloaded an image, you can generate an SHA-256 checksum for it and verify that the checksum value matches the one listed on the site. ![]() ![]() The most common use of checksums is for checking if a downloaded file is corrupted.įor instance, the Ubuntu MATE download page includes an SHA-256 checksum for every image it makes available. Linux distribution images, software packages, etc. You’ll generally find them when downloading files from the web, e.g. So a checksum is a long string of data containing various letters and numbers. In technical terms,Ī checksum is a small-sized datum from a block of digital data for the purpose of detecting errors which may have been introduced during its transmission or storage. A checksum is like the digital fingerprint of a file.
