This stuff makes me want a "mark abusive" button, so I won't accidentally participate in this next year.

Hope this helps, if you get the bad decrypt error just add -md md5 at the end of the command, this is due to the change in openssl 1.0 which uses md5 to 1.1 which uses sha256.

I didn't like this CTF, it was rather a poor quality one.

+ They partially sponsor flights for the finals
+ I liked Windows challenges, there are not many CTFs with similar ones.

- All categories contained identical kind of challenges, regardless of the category name.
- Many recon challenges.
- No IRC, the only way to contact them was via mail.
- Short scoreboard session timeout, which was really annoying.

And finally, the worst thing:
- re100 had a typo in the flag: it said that the flag is TMCTF{biscuit3_ biscuit5} (notice the space and 3&5 order), but the correct flag was TMCTF{biscuit5_biscuit3}. I informed organizers about that and received in response: "The challenge is working, with several teams solving it no problems. If you could continue working on it, then that would be great." (sic!). Other teams solved it the same way we did - guessing what typo they made in the flag. They didn't respond to my next mail.

Our other team members also tried to contact them regarding bugs in challenges and received only generic responses like "Try harder".
