Hardware-accelerated cryptography for the ArduinoNRF board package, built on the nRF52840 CryptoCell 310 (CC310).
One friendly API for random, hashing (SHA-256/384/512, HMAC, HKDF), symmetric ciphers (AES-CBC/CTR/GCM, ChaCha20-Poly1305), elliptic-curve (ECDSA/ECDH P-256, X25519, Ed25519) and RSA-2048 PKCS#1 v1.5 + SHA-256. v0.7.1 adds OnChip software AES-GCM and ChaCha20-Poly1305 (SoftAesGcm, SoftChaChaPoly). CC310 hardware via Nordic CRYS when vendored; OnChip fallback otherwise. Requires ArduinoNRF (nrf52). See docs/VENDORING.md and docs/ONCHIP_BUILD.md.
