Data Structures
struct	keccak_state_t
	Context for operations on a sponge with keccak permutation. More...

Macros
#define	SHA3_256_DIGEST_LENGTH   32
	Length of SHA3-256 digests in bytes.
#define	SHA3_384_DIGEST_LENGTH   48
	Length of SHA3-384 digests in bytes.
#define	SHA3_512_DIGEST_LENGTH   64
	Length of SHA3-512 digests in bytes.

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.
void	Keccak_update (keccak_state_t *ctx, const unsigned char *input, unsigned long long int inputByteLen)
	Absorbs data into a sponge.
void	Keccak_final (keccak_state_t *ctx, unsigned char *output, unsigned long long int outputByteLen)
	Squeeze data from a sponge.
void	sha3_256_init (keccak_state_t *ctx)
	SHA3-256 initialization.
void	sha3_update (keccak_state_t *ctx, const void *data, size_t len)
	Add bytes into the hash.
void	sha3_256_final (keccak_state_t *ctx, void *digest)
	SHA3-256 finalization.
void	sha3_384_init (keccak_state_t *ctx)
	SHA3-384 initialization.
void	sha3_384_final (keccak_state_t *ctx, void *digest)
	SHA3-384 finalization.
void	sha3_512_init (keccak_state_t *ctx)
	SHA3-512 initialization.
void	sha3_512_final (keccak_state_t *ctx, void *digest)
	SHA3-512 finalization.
void	sha3_256 (void *digest, const void *data, size_t len)
	A wrapper function to simplify the generation of a hash, this is useful for generating SHA3-256 from one buffer.
void	sha3_384 (void *digest, const void *data, size_t len)
	A wrapper function to simplify the generation of a hash, this is useful for generating SHA3-384 from one buffer.
void	sha3_512 (void *digest, const void *data, size_t len)
	A wrapper function to simplify the generation of a hash, this is useful for generating SHA3-512 from one buffer.
