void ocrypto_shake256_ext	(	ocrypto_shake_ctx *	ctx,
		uint8_t *	r,
		size_t	r_len )

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

SHAKE256 extended output.

Generates additional output data of length r_len and updates the generator state ctx accordingly. The variable length output is put into r.

Parameters

	ctx	Generator state.
[out]	r	Generated output.
	r_len	Length of r.

Remarks

Initialization of the generator state ctx through ocrypto_shake_init, ocrypto_shake256_update, and ocrypto_shake256_final is required before this function can be called.
