"UPSKiRT" CrackME
- serial verification uses elementary number theory
- uses just four or five different calls to custom big number lib
- values of big numbers in memory are EXTREMELY obvious
The serial verification is based on a single call, no decoys. The only anti-debug is distracting multimedia :) I apologise in advance if any bugs are found. Kindly report them immediately. Crackme and a working keygen were tested on 32-bit XP SP2.
Keygen only! Enjoy!
UPDATE! Numernia has solved my crackme in an impressive manner! See his solution in my solutions link or on crackmes.de. I've decided also to release the keygen I made during testing for another angle at the problem.
