Thank you very much for the contribution made by the forum to this Puzzle Event. Following the prompts, we successfully cracked part_2.zip, but we also encountered difficulties with part_3.zip. Due to the time difference, when we planned to continue cracking the next day, we found that the password for part_3.zip had already been released,

According to the prompt in part_3.zip, quickly crack 10 hash codes

But I'm not sure what to do next after the cracking is completed, or who to send the cracking results to before it's all over. Later, the moderator replied that I already have all the information to unlock the encrypted wallet with three passwords. At this point, I am at a stalemate because I have never used an encrypted wallet (only the wallet in the hosting system of this website). What is an encrypted wallet? How to use it, for which I have read a lot of information but still know nothing, can only be unlocked by others after more than ten hours


I am just a hash cracking enthusiast and I find it very fun to participate in this Puzzle Event for the first time

Because my native language is not English, I couldn't understand many prompts. I did a lot of translation and search, and finally cracked three questions (excluding the second one's published answer). Due to the time difference, I didn't see the prompts until more than ten hours later.



final, Cylone and Flagg as a team won!

I haven't seen any replies from them in the post. Is there any other communication platform besides the forum? Or private message



I hope the upcoming Puzzle Event can inform us in advance how to ultimately claim rewards. I believe that claiming rewards should not be a problem, as it is the biggest obstacle for those who have not used encrypted wallets. We are hash crackers, not researchers in encrypted wallet technology.

Although I didn't unlock my wallet to receive the reward, I am still very happy because it is my first time participating in such an event.



My question was originally intended for the administrator, but I didn't know how to send it and could only post it. I haven't woken up yet and have been complaining a lot. I also forgot the questions and suggestions I thought about before, hahaha



If what I said is wrong and the suggestion is invalid, please ignore it. Thank you

Good job mate. I congratulate both "Cylone and Flagg" and thanks to the forum for the event.

I check the pdf they posted. It's well deserved I see.

Yes in the contest thread we added a writeup yesterday for solving this challenge.

Many cryptocurrency wallet types are generated starting from a secret private key which is a 64-length hexadecimal string. I'm not going to pretend to be an expert on all these crypto algorithms but this is my understanding. Once we saw the last 10 hashes cracking to hex strings we thought that they could possibly combine somehow into a private key.

You can see on this website here sort of how it works:

For example take the private key in hex that we put in the writeup and enter into the "Secret Exponent" field. In the case of this contest they used a Compressed address so click that toggle.

You will see that it should generate both the base58check of the address as well as the WIF (wallet-import-format) private key. I apologize as in the writeup we accidentally posted the base58 value instead of the more commonly used base58check value, but I will see if Cyclone can fix it.

The WIF value should have been listed in base58check:
