Is there an alternative for the Windows software "hashcheck" in Ubuntu?

Question

hashcheck checks for matches of many common hash codes. (See http://code.kliu.org/hashcheck/)

Is there an alternative for this software for Windows on Ubuntu?

Answer 1

Most sum checking utilities are already included in Linux as command line programs - a few can be listed by running ls $(echo $PATH | sed -e s/:/' '/g) | grep sum (which searches the directories of executables to find filenames containing sum) :

sum
cksum
md5sum
md5sum-lite
sha1sum
sha224sum
sha256sum
sha384sum
sha512sum
shasum
sum

So you can get the md5 sum by running:

md5sum /PATH/TO/FILE(S)

and the sha1 sum by running:

sha1sum /PATH/TO/FILE(S)

and the sha256 sum by running:

sha256sum /PATH/TO/FILE(S)

The Ubuntu Desktop 24.04 .iso file is 6.1 GB. If the .iso file size is big, wait for a minute or two for the sha256sum /PATH/TO/FILE.iso command to finish executing. It will get there.

For other commands (although these usually use a similar syntax), you can search for their usage & options online or by using manual or help commands:

man cksum
cksum --help

MD4: I do not think has been used or included much outside of Windows for a few years due security concerns, although the rhash package appears to support it.

If you want a GUI, as this suggests, you can use this:

or other similar Ubuntu packages like GtkHash (sudo apt install gtkhash)

Answer 2

GtkHash

sudo apt install gtkhash

Click the icon of the folder at the end of the File: field, press Enter, and click the Hash button to display the checksum hashes. The Ubuntu 24.04 .iso file has a separate SHA256 checksum file used for checking it called SHA256SUMS. The downloaded .iso file is verified if the SHA256 checksum in GtkHash matches exactly to the SHA256 checksum in SHA256SUMS.
