Brute-Force Polynomial for Coefficients.


Here is a keygen challenge I got recently. This one requires to find the coefficients of a 26th degree polynomial that sums up to a specific value. A valid serial is also provided. The challenge is to code a keygen with least / reasonable time complexity without patching anything. Updated author's solution, working sample code that needs improvements.


  • Valid Keys from Keygen
  1. 3FGJL48P3IBH41DN9DOQJ6DMQJ
  2. OD2FMQGM466L99FC29LNDQC9ZI
  3. LKGGH247NQ93O6KH13IFZQ99EQ
  4. 38OQH5M4F0GKC9M15OC7B8CCJN
  5. J7DI9P4812FJNFNQ5HJ9M4DQMK
  6. 06BNIQFKJ7AFC6G9GO599M25KP
  7. 0012002001110212111102103Z

The Keygen is not stable and is based on the code from Author's Solution Section.
