ocrypto_ascon_xof128_final()

void ocrypto_ascon_xof128_final	(	ocrypto_ascon_hash_ctx *	ctx,
		uint8_t *	h,
		size_t	h_len )

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

Ascon-XOF128 output.

The generator state ctx is updated to finalize the hash for the previously processed message chunks. The output is put into h.

Parameters

	ctx	Generator state.
[out]	h	Generated output.
	h_len	Length of h. May be 0.

Remarks

Initialization of the generator state ctx through ocrypto_ascon_xof128_init is required before this function can be called.

After return, the generator state ctx must no longer be used with ocrypto_ascon_hash256_update and ocrypto_ascon_xof128_final but can still be used with ocrypto_ascon_xof128_ext to generate more output.
