The private key was small but I suppose it was considered adequate at the time of release; it was cracked a long time ago (late 2009 was when I first learned of it) and an earlier keygen exists. Stuff like this tends to remain private/hard-to-discover, but I'm not surprised to see it publicised now.

Here's some more details:

The key phrase is at the end: "Therefore, the complexity of computing the private key k is O(2^31)"

That forum post is an uncredited reprint of the years-earlier MSKey Readme[1], a brief history of which I've outlined in the first footnote on this blog post[2].

It's so odd to me that people are trying to RE an executable here. Like if I cracked a crypto system just for community credit I'd rather blog the algorithm than release a closed source executable. Seems to happen a lot in these cracking communities though.

This can't possibly work, there's not a single line of code in there that plays those sweet mod tunes that every good keygen plays when you start it. All kidding aside, this looks like a fork or reimplementation for the tool that got popular recently, based on a blog post from a few years back.

I've been setting up a WinXP PC for old games (Command & Conquers, etc) and re-discovered the "Fighting 4 FUN" multi-keygens (hundreds of EA games in a single 100KB-ish keygen)

The music is delightful https://www.youtube.com/watch?v=KE2uyF4PzNI
