void ocrypto_ecdsa_p256_det_sign_hash	(	uint8_t	sig[64],
		const uint8_t	hash[32],
		const uint8_t	sk[32]
	)

#include <crypto/nrf_oberon/include/ocrypto_ecdsa_p256_det_sign.h>

ECDSA P-256 deterministic signature generation from SHA256 hash.

The message hash hash is signed using the secret key sk and a session key calculated from hash and key. The signature is put into sig.

Parameters

[out]	sig	Generated signature.
	hash	Input hash.
	sk	Secret key.
