ISO check
The wiki has instructions on how to check the iso that users download. https://wiki.manjaro.org/index.php/Check_a_Downloaded_ISO_Image_For_Errors
The page refers to the old OSDN page where listing content of folders was possible and sha hashes where available.
See discussion: https://forum.manjaro.org/t/some-links-dont-work-some-formatting-issues-and-other-problems-in-the-wiki/84990/7?u=hanzel
Either it should be easy to find the sha1 & sha256 hashes on the downloads page or in the folder where the iso resides?
