please explain the hash

[dentad]

Greetings,

I am installing TDM for the first time, and inside the file hash.txt is zsMH:<hash>.

I know what MD5, SHA256 are etc. but what is zsMH and how do I verify it?

Ehm... I see you are a tech-savvy user if you care about hash verification

Normally, you can ignore this hash if you download the program from the official website: www.thedarkmod.com
It is there for tdm_installer's self-update: thanks to this file it can learn when new version has been posted on mirrors, without downloading the whole file every time.

But if you really want to check it, zsMH is not the name of the hash.
The hash is computed with BLAKE2s hash function.
Compute if for tdm_installer.exe or tdm_installer.linux64, and it should match.

Thank you:

$ b2sum -a blake2s tdm_installer.linux64

$ cat hash.txt
zsMH:5644d1a1b4c17f9d5abeb9c5e8517c10d269cc0174fac16842a9205180e50f4f

Yes I am technical I speak code -> C++, Rust, Python.

To be fair, the fact you're checking the Linux version of tdm_installer also makes for a strong suggestion of the technical type.

In any case, play TDM, it's a good way to deal with the (hopefully short) lockdown...

I extracted the Windows TDM Installer zip to my Desktop; now I have a hash.txt file there. Should I move it to my 'darkmod' game directory, or delete it? I use Win10.

Based on stgatilov's post, I can't tell if it exists just for the initial download, or if the TDM updater will keep using it in future TDM version updates

You can delete it.

It is important that this file is present on TDM server, because it is used for self-update. But after you download zip file, it has no use.
