ECC / ECDSA (Software)
----------------------
NuttX also provides a lightweight ECC implementation and public API in
``include/crypto/ecc.h``. It can be used for ECC key generation, ECDH shared
secret computation, and ECDSA sign/verify. Public key export is available in
compressed form (``ECC_BYTES + 1``) as well as X/Y uncompressed form.
