Run the following Python snippet in a standalone terminal or Maya's script editor to generate its trusted SHA-256 hash:
If you are an independent artist opening files from external clients or unknown web sources, you can native-block unauthorized startup scripts directly via preferences:
import os import hashlib import json import sys def calculate_sha256(filepath): """Calculate the SHA-256 checksum of a file.""" hasher = hashlib.sha256() try: with open(filepath, 'rb') as f: while chunk := f.read(8192): hasher.update(chunk) return hasher.hexdigest() except FileNotFoundError: return None def verify_pipeline_integrity(): """Verify scripts against the trusted manifest.""" manifest_path = "/network/secure_pipeline/maya/config/allowed_hashes.json" script_dir = "/network/secure_pipeline/maya/python" # Load trusted hashes try: with open(manifest_path, 'r') as f: trusted_manifest = json.load(f) except Exception as e: sys.stderr.write(f"[SECURITY ALERT] Failed to load integrity manifest: e\n") os._exit(1) # Hard exit Maya immediately # Verify each registered file for filename, trusted_hash in trusted_manifest.items(): target_file = os.path.join(script_dir, filename) current_hash = calculate_sha256(target_file) if current_hash is None: sys.stderr.write(f"[SECURITY ALERT] Missing critical script: filename\n") os._exit(1) if current_hash != trusted_hash: sys.stderr.write(f"[SECURITY ALERT] Checksum mismatch detected on: filename!\n") sys.stderr.write("The file may have been tampered with.\n") os._exit(1) # Run the integrity check before Maya executes any other tools verify_pipeline_integrity() print("[SECURITY] Pipeline integrity verified successfully.") Use code with caution. Step 3: Deployment Best Practices maya secure user setup checksum verification
: Grant absolute read-only access to the network script directories and configuration manifests.
If even a single character, space, or line break changes within the script, the resulting checksum changes entirely. By calculating the checksum of your userSetup files at startup and comparing it against a known, pre-approved "golden master" hash, you can instantly detect tampering. Implementing a Secure Bootstrapping System Run the following Python snippet in a standalone
Open Maya and navigate to . Select the Security settings category on the left panel.
In simple terms: If even one character changes in the original data, the checksum changes completely. By calculating the checksum of your userSetup files
To enforce this via script during your secure startup sequence, add these commands:
