 Elliptic Curve Cryptography (ECC) is a type of public-key cryptographic system.
 This class of systems relies on challenging "one-way" math problems - easy to compute one way and intractable to solve the "other" way.
-Sometimes these are called "trapdoor" functions - easy to fall into, complicated to escape.<sup>[2]</sup>

 ECC relies on solving equations of the form
 $$y^2 = x^3 + ax + b$$

 **Fixed in v2.2**.
 * Some Windows XP VLK keys tend to be "worse" than others. Some of them may trigger a broken WPA with an empty Installation ID after install.
 You have the best chances generating "better" keys with the `BBB` section set to `640` and the `CCCCCC` section not zero.
-* Windows Server 2003 key generation is broken. I'm not sure where to even start there. The keys don't appear to be valid anywhere,
-but the algorithm is well-documented. The implementation in my case generates about 1 in 3 "valid" keys.
