Where do these keys come from?
These keys were retrieved from OEM SLP systems that are being sold by the big OEM vendors.
OEM SLP Keys:
OEM SLP (System-Locked Pre-installation) keys are only issued to the big manufacturers such as Dell, Asus, Sony, etc.
These are the only keys that are able to bypass activation that is, perform offline activation without contacting Microsoft.
They will work with any OEM SLP system, regardless of the OEM system's brand i.e. Product Keys are not brand specific.
What is SLP 2.0?
This mechanism referred as 'SLP 2.0' ('system-locked pre-installation 2.0') consists in THREE (3) elements:

HEX: 54 4F 53 51 43 49 54 4F 53 51 43 49 30 30
A certificate issued by Microsoft that corresponds to the specific ACPI_SLIC information. Something like

Is the OEM SLP license mechanism a crack?
There is no cracking here; the OEM SLP license mechanism was created by MS and is completely legitimate.
