C++ (Cpp) flip64 Examples

Example #1

File: algorithm.c Project: cryptocurrent/sgminer

void sha256d_midstate(struct work *work)
{
  unsigned char data[64];
  uint32_t *data32 = (uint32_t *)data;
  sph_sha256_context ctx;

  flip64(data32, work->data);
  sph_sha256_init(&ctx);
  sph_sha256(&ctx, data, 64);
  memcpy(work->midstate, ctx.val, 32);
  endian_flip32(work->midstate, work->midstate);
}

Example #2

File: miner.c Project: homolumo/mm

static void calc_midstate(struct mm_work *mw, struct work *work)
{
	unsigned char data[64];
	uint32_t *data32 = (uint32_t *)data;

	flip64(data32, mw->header);

	sha256_init();
	sha256_update(data, 64);
	sha256_final(work->data);

	/* FIXME: LM32 will crash if I direct use
	 * flip64(work->data, work->data);
	 * Should be flip32 ??
	 */
	memcpy(data, work->data, 32);
	flip64(data32, data);

	memcpy(work->data, data, 32);
	memcpy(work->data + 32, mw->header + 64, 12);
}

Example #3

File: miner.c Project: HashRatio/mm-hashratio

	uint32_t *data32 = (uint32_t *)data;
