Quake Shareware, a CD-ROM just a little too full

📝 Discussion Summary (Click to expand)

1. “Security through obscurity” vs real crypto

“Is it really fair to call these such algorithms ‘security through obscurity’?” – ranger_danger

2. Distribution via sneakernet and floppy disks

“I was 12 years old and had qcrack on a floppy from a buddy. Everyone had it. Didn’t even have to have internet.” – mikestorrent

3. How per‑CD encryption could have been implemented

“How would your scheme work? You use RSA to encrypt the entire thing? Or you use it to get a key for a block cipher and then use that?” – ekelsen
