    3:50 "Our stupid human eyeballs" is gonna be running through my head all day. Thanks for these walk throughs! I've been completing the ones you release, then watch the video to compare methods/thought processes.

    These short videos are great. Funnily enough I enjoy a bit of stego but that may have stemmed from a past interest in cicada3301 puzzles. I mainly use stegoveritas but might have to give zsteg a good look over. but i admit It is a fairly dull area of the industry, there's either something hidden or there isn't, and the biggest challenge is finding the right tool or method and there isn't much else to it, just hide and seek type stuff.

    Hey, John, I am a big fan of your walk-throughs. I did the whole Pico Practice Gym, so it is kind of cool to watch you work through the same problems, sometimes solving in a whole different way than did I. I never had a IRL steg case, but knowing how that works is helpful for things like encrypted blobs. Hang in there, man. A large group of people enjoy your work.
  • @cyberrick5142
    Love this! Steganography is fascinating. Thanks for the instruction.

    Hey John! Another great video and solid explanations from you. I´m really looking forward to any new video. You´ve got such an interesting way of teaching IT-stuff. Seeing your skills makes me rethink my career and consider studying again, but this time in the field of IT/IT-Forensic. Please keep up the good work. A donation is on its way.

    8:00 "I saw something in bright red" ... I could only see MATRIX code :D
  • @GrandpaGameHacker
    This came up in a video game community im in. There is a hidden xor encrypted QR code that has a lot of image noise inside the executable. I couldnt find anything yet on why the noise is there. Anyone with suggestions please respond! Cool video! Love it

    If you going to be a Computer Forensics Examiner or anything to do with Forensics, Steganography is important part of your arsenal.

    i like to take breaks from studying C++ and watching you makes me feel like im not being useless but i can't say i understand what you are doing , i understand what you are saying if that is enough, then i go back to studies, then i just basically for(int i ; i < 100000; i++) loopidy loop what do i study next after i finish this 31 hour course? i was thing python or c# ..... but i would like a professional recommendation, also i have no idea what i want to become , i just know if i study hard enough i can become it .
