| Zer0Mem0ry 02. Nov, 21:27 | It was fairly easy to crack this crackme, but it definitely was really fun too! It took me only about 10 minutes in total, even though the strings were encrypted it was really easy to see how the program dealt with the input keys. It was as easy as just changing the entry point's last jmp instruction to jump to location text:00401873 instead of jumping to text:00401842 where the argument input took place. Thanks for this challenge! |

| siir 21. Nov, 19:15 | I liked it. Took me a while as I'm learning but I finally got it. The key is at 0040410C (52 bytes). |
| darkHorus 03. Dec, 17:49 | Great exercise! Actually, it was pretty easy to get the encrypted key location, but the best and most interesting thing was to discover this message: "Never compromise not even in the face of armageddon." |
