- Implemented ChaCha20-based CSPRNG seeded from SE050 TRNG
- Optimized for ESP32 and other embedded platforms
- Single SE050 access at startup, then fast software RNG
- All 10 CSPRNG tests passing
Usage:
Benefits:
- Minimal I2C communication (only once at startup)
- Fast random generation after seeding
- Cryptographically secure (ChaCha20-based)
- Suitable for resource-constrained devices
