If found, enter the recovered password into RSLogix 5000. Unprotect the routine.
Extract the hash from the .ACD file. The protection data is stored in a LogixSourceProtection stream. Command: python extract_hash.py your_file.ACD rslogix 5000 source protection decryption tool
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. If found, enter the recovered password into RSLogix 5000
