Tut available

Squidge, you said there're no tuts for decrypting and seperating master and user keys available.

At Anticrack.de I found a tut which discusses the complete internals of CrypKey including how CrypKey stores license info on the HD, how CrypKey encrypts/decrypts Site Codes/Site Keys/Master Keys/User Keys, the structures of (decrypted) Site Codes/Site Keys/Master Keys/User Keys, how it generates Site Keys from Site Codes and much much more.

It's quite interesting to see that CrypKey uses Slack Space on FAT partitions in order to store the license info securely.

Also it is interesting to read how the guys at Kenonic implemented RSA into CrypKey. Very "secure"

The complete tut/essay about this "battle-proven software protection system" is very interesting and I suggest to read it

Well, that's something I didn't know. I pretty much did all the reversing work myself. Thanks for the info

Unhappy Thx for this link

However, I couldn't download it from there...

When I press "executable" in download section it simply displays a Lycos page in a small window and then it returns to the main page

Any suggestions?

to download from lycos you need to submit your brower referrer information. if you have a firewall installed this information may be blocked.

Normally, I tell people to go and find the tools themselves, but on this occasion, I think it'll be easier for everyone if it was just uploaded here.

So here goes.

Note that this is the executable version ONLY. No example/scripts etc. You'll have to get those from the website that thewd posted.

This is v1.08, which I assume is the latest (public) version.

I didn't post this earlier, as I didn't know whether thewd wanted the tool made this public, but since it's on his website...

Thanx Squidge

@thewd: I have no firewall running and my browser security setting is set to low. But I can't download it. I've just tried it.
