Error decrypting with Planet Minecraft

The modification doesn't seem to work with Planet Minecraft

Unsure what causes this. I took the public key from votifier/public.key. Tried deleting the votifier folder to generate a new key, but that new key didn't work either.

Is this problem specific to planet Minecraft or does it occur on other vote sites as well?
Make sure to double-check that the keys match (no extra spaces, deleted characters...)

Answer 2 · 2021-07-12T12:57:38.000Z

I have double checked the keys match. I haven't tried with other voting lists since I am not on them. I tried to find some other people running this mod, but I have been unsuccessful.

I am very sure the keys match. I wonder whether Planet Minecraft mistakes the key for a token. The key doesn't look like a typical RSA key to me. I will do some more testing later today.

I tested with minecraftservers.org, and that gave a similar error.

I am using the key inside public.key.

I just tried myself using fabric-votifier-1.1.3.jar on mctools and couldn't replicate your issue.

Answer 5 · 2021-07-12T21:58:40.000Z

I can confirm it works with mctools. Not with Planet Minecraft or minecraftservers.org.

Answer 6 · 2021-08-28T21:24:54.000Z

I have recently encountered a similar issue with minecraftservers. Apparently, they have added a whitelist of trusted votifiers and wouldn't handle Fabric Votifiers requests, because it used a different id. I have just committed a fix that fixed this issue for. Maybe this also fixes your problem. Please let me know :D

That fixed it on Planet Minecraft too! Thanks!
