uint32_t unlock(uint32_t stored_hash) // Reverse the XOR‑mask applied during password creation uint32_t mask = 0xA5A5A5A5; return stored_hash ^ mask; Many of these tools are remarkably simple
Because the mask is constant across many Delta models, the same routine works for a broad device range.
: Usually requires the password. If you do not have it, you cannot retrieve the program currently running on the HMI.
