Dela Cruz blinked for a moment, trying to process the chain of logic.
Jeff remained steady, his eyes were clear as the day.
"So what will happen if the hash doesn't match?" he asked.
"Well, if it doesn't match, nothing will happen. The system won't even respond. To anyone else, it just looks like the app is frozen," Jeff answered.
"But with the correct phrase, the system returns a unique code that can be cross-verified with my private signature database," he clarified.

Dela Cruz stared at him, eyes wide now, "You seriously thought of everything, huh? I thought I was going to teach you something, but that doesn't seem to be the case. Haha," he laughed at the end.
Jeff, seeing this, gave the faintest smile, "Well, it is always good to prepare for thieves, sir," he replied.
