I’ve developed a unique encryption system called *D256* that works completely offline — no internet, no devices, no code — just real-world variables and mathematical logic.
### What is D256?
D256 is a cipher system based on:
- The day that falls 256 years before the current date - 12-hour clock time converted to decimal - Ambient temperature at encryption - A prime number assigned weekly - Boiling time as entropy - Plus, each character is indexed and encoded using per-digit logic
Together, it creates a strong, adaptive encryption formula that works entirely without digital systems — making it immune to most modern attacks.
> You can encrypt messages using just a paper, thermometer, and clock.

### What I'm Offering
I'm selling *exclusive rights* to the system: - Fully illustrated PowerPoint presentation - License Agreement granting full ownership - README + authorship credits - Packaged in a downloadable ZIP file
*Only one person/company will ever own or resell this version.* *Price: $1,999 USD (one-time)*

### Why Am I Posting Here?
- Looking for someone who sees value in unique, offline encryption - Open to feedback on presentation, math, or commercial use - If you know someone in cybersecurity, crypto-art, or defense — this might be for them

### Preview or Demo?
I’m happy to show parts of the presentation or explain how the cipher works if anyone is curious. Ask me anything!
Thanks, *Haroon Sharif*
