by modmusnikolas

VortexIntegrity Client is a Fabric mod that sends a hash of the player's installed mod files to the VORTEX.CZ server, where the hash is checked against an approved modpack signature.

FabricClient-side onlyAll rights reserved26.1.2

What it does

When the game launches, the mod generates a unique SHA-256 hash based on the exact filenames in the mods folder. On connecting to a server that runs the matching official plugin, the hash is sent through a dedicated custom packet channel, and the server compares it with the approved modpack signature. A match grants access at once.

The mod is built for the VORTEX.CZ server and is meant to keep play fair by blocking unapproved client-side modifications and cheats. Connections attempted with a vanilla client without the mod are detected and blocked within four seconds. The mod runs on the client only and does not interfere with Spigot or Paper server software.

Installation needs Fabric API. The client-side only environment means only the player's client needs the mod. VortexIntegrity Client is not open source and is released under All rights reserved. It has a single build, 1.0.0 for 26.1.2, published on 2026-07-07.

Key features

  1. Automated hashing

    A SHA-256 hash is computed from the exact filenames in the mods folder each time the game starts.

  2. Instant verification

    The hash travels over a custom packet channel to the server plugin, so no manual step is needed when joining.

  3. Strict validation

    The server checks the client's hash against the officially approved modpack signature and grants access only on a match.

  4. Handshake bypass detection

    Attempts to join with a vanilla client, without the mod, are flagged and blocked within four seconds.

Questions

Does VortexIntegrity Client need Fabric API?

Yes. Fabric API is the required dependency, so it must be installed next to VortexIntegrity Client on Fabric 26.1.2.

Does the server need this mod installed?

Players add it to their own game, and a server needs no copy. The server side runs through the official plugin, which is separate from the client mod.

Which game version is supported?

The mod is published only for 26.1.2, with the single file 1.0.0 released on 2026-07-07.
