Function Documentation

sph_jh224()

void sph_jh224	(	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 JH-224 context
data	the input data
len	the input data length (in bytes)

Definition at line 1011 of file jh.c.

sph_jh224_addbits_and_close()

void sph_jh224_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 JH-224 context
ub	the extra bits
n	the number of extra bits (0 to 7)
dst	the destination buffer

Definition at line 1025 of file jh.c.

sph_jh224_close()
