void ocrypto_curve25519_scalarmult_ctx	(	ocrypto_curve25519_ctx *	ctx,

		const uint8_t	n[(32)],
		const uint8_t	p[(32)] )

#include <crypto/nrf_oberon/include/ocrypto_curve25519.h>

Curve25519 scalar multiplication r = n * p with context.

A shared secret is computed from the local secret key n and another party's public key p and put into r. The same shared secret is generated when the other party combines its private key with the local public key.

Parameters

	ctx	Context.
[out]	r	Resulting curve point.
[in]	n	Scalar factor.
[in]	p	Point factor.

Remarks

r may be same as n.
