My .bisign/.bikey doesn't work

[Rautapalli]

I can't get my addon signatures working.

The steps I took while creating them:

I created the .biprivatekey and .bikey with DSCreateKey, that worked fine. Both files showed up in the folder.
I went into binpbo options and added the path to my .biprivatekey.
I checked "create signature" in the main windows of binpbo.
I packed the addon.
It created the .pbo and .bisign properly, the addon works fine in singleplayer.
But then I moved the .bikey file into the keys folder on my server and tried joining it and I just get the usual "myaddon.pbo signature is not accepted by the keys on the server" error.

I've tried restarting the server and my client multiple times, I've tried repacking the addon and creating a new key, but nothing seems to work. Same error every time.
I even tried DsCheckSignatures, I ran it through in cmd with the correct folders and it didn't output anything, I assume that means the key is supposed to work?

Does anyone have a clue what I'm doing wrong?

Edit: Oh and I also saw this thread, but changing my Windows password and repeating the process didn't do anything, same error.

Oh goddamn it, apparently my version of BI Tools was outdated and it was generating v1 keys instead of v2 keys. Case solved.
