Designed to safeguard intellectual property (IP), source protection allows developers to lock routines, programs, or add-on instructions (AOIs) with a password. This prevents unauthorized viewing or modification of the critical logic inside.
| Tool Name | Claim | Reality | Risk | | :--- | :--- | :--- | :--- | | | Removes any v20 password | Scam; likely malware. No known tool exists for v20 SHA-512 hashes. | High (Ransomware) | | SourceProtectionCracker.exe | Instant unlock for all versions | Outdated; only works on v13–v16 with weak passwords. | Medium (False hope) | | Rockwell Password Recovery Pro | $299 – Decrypts AOIs | Legitimate brute-forcer for offline files (v19 & below). Works slowly. | Low (Overpriced) | | Logix Designer Patch (v24) | Bypasses Ultra Protection | Real, but only for v24. Requires re-downloading controller. | Medium (EULA violation) | | PLC Guard Unlock 2.1 | Claims to support v32 | Likely fake. No known exploit for modern Studio 5000 (v28+). | High (Scam) |
This has led to a dark, gray, and often misunderstood market for . Part 1: What is Source Protection? (A Technical Refresher) Before discussing decryption, we must understand the mechanism. rslogix 5000 source protection decryption tool
Introduction Rockwell Automation’s RSLogix 5000 (and its successor, Studio 5000 Logix Designer) is the industry standard for programming ControlLogix and CompactLogix programmable automation controllers (PACs). One of its most contentious features is Source Protection .
Save the hash to a file (e.g., rockwell.hash ). No known tool exists for v20 SHA-512 hashes
In RSLogix 5000 v20 and earlier, source protection works by encrypting the routine's source code (structured text, ladder, or FBD) using a password provided by the developer. The password is hashed and stored within the .ACD file (the project file) and also within the controller’s memory when downloaded.
Run Hashcat with a dictionary attack. Command: hashcat -m 17800 rockwell.hash rockwell_words.txt (Note: Mode 17800 is for Rockwell’s legacy hash algorithm) Works slowly
Gray area. Memory scrapers or executable patches exist but are risky and legally questionable.
