recovery key generation method

[nblog]

In the "Recovery Key" section，there is no mention of how to generate it, so I'll add the method for that，It comes from one of the tools I analyzed.

std::srand(static_cast<std::uint32_t>(std::time(0)));

std::array<uint8_t, 16> tmpvalue = { 0 };

for (size_t i = 0; i < 16; i++)
{
	tmpvalue[i] = uint8_t(int(double(std::rand()) * 0.000030517578125 * 255.0 + 0.0));
}

std::array<std::string, 8> blocks;

for (size_t i = 0; i < 8; i++)
{
	char szBuffer[20] = { 0 };
	sprintf(szBuffer, "%06d", ((uint16_t*)(tmpvalue.data()))[i] * 11);
	blocks[i] = szBuffer;
}

return blocks[0] 
	+ "-" + blocks[1]
	+ "-" + blocks[2]
	+ "-" + blocks[3]
	+ "-" + blocks[4]
	+ "-" + blocks[5]
	+ "-" + blocks[6]
	+ "-" + blocks[7];

@joachimmetz ，i hope this helps.

I'll have a look when time permits, the goal of this project has mostly been to read BitLocker volumes
