		const uint8_t	sk[28]
	)

#include <crypto/nrf_oberon/include/ocrypto_ecdsa_p224.h>

ECDSA P-224 public key generation.

Given a secret key sk the corresponding public key is computed and put into pk.

Parameters

[out]	pk	Generated public key.
	sk	Secret key. Must be pre-filled with random data.

Return values

0	If sk is a valid secret key.
-1	Otherwise.

Remarks

To generate a valid key pair use the following code pattern:

do get_random(sk); while (ocrypto_ecdsa_p224_public_key(pk, sk));
