Kudos to the folks who make these CTF challenges though.
Given the prompt that came with the challenge (i.e., to get the password of an encryption service), I was actually digging through system log files to see if perhaps there was evidence of some sort of service, when I found this command here.
😅 Somehow, I don't think that was how I was supposed to find the flag. But then again, they would have locked this file down, right? 🤔
