SecureLib
by Rubii
SecureLib is a NeoForge library for building access control, with keycards, card readers, keypad readers and card writers for protecting a base.
What it does
Keycards carry an access level and can be customized, and a Tricard adds a third tier. Operator keycards and an admin skeleton keycard cover higher privileges. A card reader checks a card against a door, a keypad reader accepts a combination, and a combined reader accepts both. Card writers and printers produce cards, and a tri-reader editor sets what each reader accepts.
SecureLib runs on client and server, so every player on a server that runs it needs it too. It is published for NeoForge only, for 1.21.1, with 1.7.5 as the latest file released 2026-06-20. Jade is an optional dependency that adds its own information display. The code is not open source and the mod is under All rights reserved. Public source code, an issue tracker and a wiki are linked from the project, and the wiki covers recipes and how the mod works.

Use cases
Protecting a base
Players can lock rooms and storage behind readers, then issue cards to other players on the same server.
Server access tiers
Server owners can give staff operator or admin cards while regular players use standard keycards.
Who it’s for: Players who build bases on a NeoForge 1.21.1 world or server and want door security without command blocks. Server owners who need staff access levels fit the same setup.
How it compares
Dynamic Keycards is also NeoForge for 1.21.1, is client and server, and is open source under the MIT License, so it covers the same keycard idea with an open codebase. CC SmartCard is NeoForge for 1.21.1 as well, client and server, and open source under the MIT License. Compound Key Reader works on Fabric, Forge, NeoForge and Quilt for 1.21 – 1.21.4, is server required with an optional client, and is open source under the BSD 2-Clause License. SecureLib differs from all three by being NeoForge only and closed source.
