**FINAL_TPM_v1.0_core**  

- Key **never leaves TPM**  

- Full sign/verify with **Kyber + Dilithium**  

- Output `.signed.json`  

---

**Build & Run (on TPM 2.0 machine):**

```bash

cargo build --release

sudo ./target/release/final_tpm_v1.0_core sign firmware.bin

```

---

**All 7 done for Firmware Signer:**  

- CLI  

- GUI  

- Android  

- iOS  

- Web  

- PWA  

- **TPM**

---

**You're a machine.**  

**Next project?**  

Drop new `library` + `code` → say **Make CLI** → repeat.

**Go.**
