◆ sph_keccak224()

void sph_keccak224	(	void *	cc,

Process some data bytes.

It is acceptable that len is zero (in which case this function does nothing).

data	the input data
len	the input data length (in bytes)

void sph_keccak224_addbits_and_close	(	void *	cc,
		unsigned	ub,
		unsigned	n,
		void *	dst
	)

Add a few additional bits (0 to 7) to the current computation, then terminate it and output the result in the provided buffer, which must be wide enough to accomodate the result (28 bytes).

If bit number i in ub has value 2^i, then the extra bits are those numbered 7 downto 8-n (this is the big-endian convention at the byte level). The context is automatically reinitialized.

Parameters

cc	the Keccak-224 context
ub	the extra bits
n	the number of extra bits (0 to 7)
dst	the destination buffer

The destination buffer must be wide enough to accomodate the result (32 bytes). The context is automatically reinitialized.

Parameters

cc	the Keccak-256 context
dst	the destination buffer

◆ sph_keccak256_init()

void sph_keccak256_init ( void * cc )

Initialize a Keccak-256 context.

This process performs no memory allocation.

Parameters

cc	the Keccak-256 context (pointer to a `sph_keccak256_context`)

Definition at line 1739 of file keccak.c.

References keccak_init().

◆ sph_keccak384()

void sph_keccak384	(	void *	cc,
		const void *	data,
		size_t	len
	)

Process some data bytes.

It is acceptable that len is zero (in which case this function does nothing).

Parameters

cc	the Keccak-384 context
data	the input data
len	the input data length (in bytes)

◆ sph_keccak384_addbits_and_close()

void sph_keccak384_addbits_and_close	(	void *	cc,
		unsigned	ub,
		unsigned	n,
		void *	dst
	)

Add a few additional bits (0 to 7) to the current computation, then terminate it and output the result in the provided buffer, which must be wide enough to accomodate the result (48 bytes).

If bit number i in ub has value 2^i, then the extra bits are those numbered 7 downto 8-n (this is the big-endian convention at the byte level). The context is automatically reinitialized.

Parameters

cc	the Keccak-384 context
ub	the extra bits
n	the number of extra bits (0 to 7)
dst	the destination buffer

void sph_keccak512_addbits_and_close	(	void *	cc,

		unsigned	n,
		void *	dst
	)

Add a few additional bits (0 to 7) to the current computation, then terminate it and output the result in the provided buffer, which must be wide enough to accomodate the result (64 bytes).

If bit number i in ub has value 2^i, then the extra bits are those numbered 7 downto 8-n (this is the big-endian convention at the byte level). The context is automatically reinitialized.

Parameters

cc	the Keccak-512 context
