@QQQ126 I can try that for you

Maybe you could help me with:
You've registered for an online service that uses hash chains.

You've registered as user 'nOOB’ and have been given the hash chain seed 654e1c2ac6312d8c6441282f155c8ce9

Use the given information to figure out how to authenticate as the user 'ECSC' for the given challenge hash c89aa2ffb9edcc6604005196b5f0e0e4

i.e. Find the hash that hashes to this - This hash will be your solution.

For user nOOB used MD5,
IDK what i should to do with second part, have I use any blockchain algorithm before decode a hash?

I am having this same issue. Can anyone help?

Well? absolutely not clear
where to insert what to do
for whom is this
if you are a professional coder, I think, and without this "smart file" it will be clear what to do, but for the noobs only gets angry?

dear I will do brute force for you if you remember some part of your password

My Ethereum *.json wallet that I bought at Ethereum crowd sale (Genesis). Unfortunately I don't know the password anymore.

How can i recover it? plz help me out.

you may reach BTC recover , if you know what possible symbols you used, there is a good chance to recover it.
Ethereum presale wallet 🐞 password with special characters: symbols : (https://www.youtube.com/watch?v=BrFSYA9778w)

I have an imported wallet aes.json file to be open in blockchain.info and believed was encrypted. I have an issue to login. My wallet password was not recognized any more. The only solution as per the technical support is to brute force the password. What is the tool to brute force the password for a layman like me. Meaning I do not have enough knowledge on programming but relying only to tutorial on that tool to use it. Any body who can share to me ideas to bruteforce it is very much appreciated and will donate if ever successful. Thank you..
