Function Documentation

sph_simd224()

void sph_simd224	(	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 SIMD-224 context
data	the input data
len	the input data length (in bytes)

Definition at line 1705 of file simd.c.

sph_simd224_addbits_and_close()

void sph_simd224_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 SIMD-224 context
ub	the extra bits
n	the number of extra bits (0 to 7)
dst	the destination buffer

Definition at line 1717 of file simd.c.

Here is the caller graph for this function:

sph_simd224_close()

void sph_simd224_close	(	void *	cc,
		void *	dst
	)

Terminate the current SIMD-224 computation and output the result into the provided buffer.

The destination buffer must be wide enough to accomodate the result (28 bytes). The context is automatically reinitialized.

Parameters

cc	the SIMD-224 context
dst	the destination buffer
