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

RSA public key setup.

Parameters

[out]	key	The initialized public key.
[out]	key_mem	Key memory. Length OCRYPTO_RSA_PUB_KEY_SIZE(bits). Must have same lifetime as key.
	n	The RSA modulus, unsigned big-endian.
	n_len	Length of n.
	e	Public exponent.

Return values

-1	If the input length is invalid.
0	On success.

Remarks

The n value can be read directly from a DER encoded RSAPublicKey or RSAPrivateKey.
