Functions
void	Keccak_init (keccak_state_t *ctx, unsigned int rate, unsigned int capacity, unsigned char delimitedSuffix)
	Initialise a sponge based on a keccak-1600 permutation. More...
void	Keccak_update (keccak_state_t *ctx, const unsigned char *input, unsigned long long int inputByteLen)
	Absorbs data into a sponge. More...
void	Keccak_final (keccak_state_t *ctx, unsigned char *output, unsigned long long int outputByteLen)
	Squeeze data from a sponge. More...
void	sha3_256_init (keccak_state_t *ctx)
	SHA3-256 initialization. More...
void	sha3_update (keccak_state_t *ctx, const void *data, size_t len)
	Add bytes into the hash. More...
void	sha3_256_final (keccak_state_t *ctx, void *digest)
