ocrypto_cshake128_ext()

void ocrypto_cshake128_ext	(	ocrypto_cshake_ctx *	ctx,
		uint8_t *	r,
		size_t	r_len
	)

cSHAKE128 extended output.

Generates additional output data of length r_len and updates the generator state ctx accordingly. The 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_cshake128_init, ocrypto_cshake128_update, and ocrypto_cshake128_final is required before this function can be called.
