SecureAuth - Secure Login for Cracked Minecraft Servers


(A shiny 3D shield - protects your server like a fortress!)

What is SecureAuth?
Hey, future Minecraft mod master! SecureAuth is a super-smart Spigot plugin I (excrele) built to keep your cracked server safe from sneaky impersonators. On cracked servers, anyone can join with any name - but this plugin fixes that! Premium players (real Mojang accounts) zoom in automatically. Cracked players? They register a super-secure password once, then login quick. No more griefers stealing your spot!

It's like a VIP bouncer: Fast for good guys, locked tight for randos. And it's all in one Java file (modular sections for easy tweaks) - no mess!

• Version: 1.0
• Spigot API: 1.20+ (works on newer too!)
• Author: excrele (that's me - hit me up for custom mods!)
• License: Free for non-commercial use - credit me if you share!

✨ Key Features (Like Superpowers!)

• Premium Auto-Login: Mojang API checks - real accounts skip the hassle!
• Secure Passwords: Hashed with SHA-256 + salt (gibberish in files - hackers cry!). No plain text, even for staff!
• Full Lockdown Mode: Until logged in? No chat, no walking, no building/breaking. Stay safe!
• Session Timeouts: AFK too long (30 min)? Auto-logout for security.
• Password Changes: /changepass to update your secret (needs old pass first).
• Admin Resets: /setpass to force-reset a player's pass (ops only).
• Login Limits: 3 wrong tries = 5 min lockout (player + IP!). Resets after 5 min quiet. Stops bots cold!
• IP Protection: Bad guesses from one IP lock the whole connection - no alt-account spam!

Pro Tip: All data in - hashed, so even if stolen, useless!

Installation (Easy as Pie!)
[olist=1]
[*] Download: Build the JAR from source (Maven: ) or grab from my repo (coming soon!). File: .
[*] Drop It In: Put the JAR in your server's folder.
[*] Restart: Fire up the server - watch console for "SecureAuth by excrele is online!"
[*] Test: Join with a premium name (like "Notch") - auto-welcome! Cracked name? Register first!
[/olist]

Requirements:

• Spigot/Paper 1.20+ (cracked mode:
  Code (Text):

  online-mode=false
  in server.properties).
• Java 21+ (for fancy hashing).

No Config? Yup! All tunable in code (e.g., timeouts in SecureAuth.java). Edit & rebuild for your vibe.

Commands & Permissions (Your Magic Words)
All commands work in-game. Permissions default friendly - tweak in LuckPerms or whatever!

Command	Description	Usage	Permission (Default)
Code (Text): /register <pass> <repeat>	Create your secure password (first time only!).	Code (Text): /register mypass mypass	Code (Text): secureauth.register (true)
Code (Text): /login <pass>	Log in with your saved password.	Code (Text): /login mypass	Code (Text): secureauth.login (true)
Code (Text): /changepass <old> <new> <repeat>	Update to a fresh password (must be logged in!).	Code (Text): /changepass myold newpass newpass	Code (Text): secureauth.changepass (true)
Code (Text): /setpass <player> <newpass>	Admin: Reset a player's password (logs 'em out).	Code (Text): /setpass Steve newpass	Code (Text): secureauth.setpass (op)

Bypass Perk: (op) - Skips all checks for trusted staff. Use wisely!

⚙️ Customization (Tweak Like a Pro!)
Open - it's one file, sectioned like a comic book!

• Timeouts: Change
  Code (Text):

  SESSION_TIMEOUT
  (30 min),
  Code (Text):

  LOCKOUT_DURATION
  (5 min),
  Code (Text):

  RESET_DURATION
  (5 min for attempt forgiveness).
• Limits:
  Code (Text):

  MAX_ATTEMPTS = 3;
  - Bump to 5 for chill servers.
• Messages: Edit the
  Code (Text):

  player.sendMessage()
  lines - add colors or emojis!
• More Blocks? Add events like
  Code (Text):

  PlayerInteractEvent
  for doors/chests.

Rebuild with Maven, restart - done! (Teen tip: IntelliJ makes this a breeze.)

️ Troubleshooting (Fix It Fast!)

• "Premium check failed": Internet hiccup? Mojang API down - treats as cracked (safe!).
• Passwords visible? Nope! Check
  Code (Text):

  passwords.txt
  - all hashes like
  Code (Text):

  uuid:abc123def...
  (unreadable!).
• Not blocking chat/move? Ensure
  Code (Text):

  online-mode=false
  . Reload plugin?
  Code (Text):

  /reload confirm
  (but restart better).
• Errors in console? Paste 'em - I'm here to debug! (Common: Java version - need 21+.)
• Too strict? Comment out event handlers (e.g.,
  Code (Text):

  @EventHandler public void onPlayerMove...
  ) for testing.

Logs: Check for warnings. All async - no lag!
