Typedef Documentation

◆ sph_luffa256_context

typedef sph_luffa224_context sph_luffa256_context

This structure is a context for Luffa-256 computations.

It is identical to sph_luffa224_context.

Definition at line 88 of file sph_luffa.h.

Function Documentation

◆ sph_luffa224()

void sph_luffa224	(	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 Luffa-224 context
data	the input data
len	the input data length (in bytes)

Definition at line 1305 of file luffa.c.

◆ sph_luffa224_addbits_and_close()

void sph_luffa224_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 Luffa-224 context
ub	the extra bits
n	the number of extra bits (0 to 7)
dst	the destination buffer
