C++ (Cpp) mir_sha1_hash Examples

Example #1

File: canvas.cpp Project: biddyweb/miranda-ng

bool Canvas::getDigest(Digest& digest)
{
	// we don't have a digest if the image is uninitialized
	if (!m_pBMIH)
		return false;

	// read data from DIB
	int nSize = m_nLineLength * m_nHeight;
	BYTE* pData = new BYTE[nSize];

	memset(pData, 0, nSize);

	if (GetDIBits(m_hDC, m_hBmp, 0, m_nHeight, pData, reinterpret_cast<BITMAPINFO*>(m_pBMIH), DIB_RGB_COLORS) != m_nHeight) {
		delete[] pData;
		return false;
	}

	// apply transparency, if any
	updateTrans(pData);

	// calculate hash
	mir_sha1_hash(pData, nSize, digest.m_Digest);

	delete[] pData;
	return true;
}

Example #2

File: avatar.c Project: TonyAlloa/miranda-dev

char *gg_avatarhash(char *param)
{
	mir_sha1_byte_t digest[MIR_SHA1_HASH_SIZE];
	char *result;
	int i;

	if (param == NULL || (result = (char *)mir_alloc(MIR_SHA1_HASH_SIZE * 2 + 1)) == NULL)
		return NULL;

	mir_sha1_hash(param, (int)strlen(param), digest);
	for (i = 0; i < MIR_SHA1_HASH_SIZE; i++)
		sprintf(result + (i<<1), "%02x", digest[i]);

	return result;
