Simple BlockChain - Challenge Lab

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.

You need to submit a Single PDF, with detailed explanation including source code used to solve the challenge.

• Ask your Python question, not if you can ask or if there's an expert who can help.
• Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
• Explain what you expect to happen and what actually happens.

Just a heads up: You're more likely to get help if you ask a specific question. Looking back on your previous posts, they're very broad, and are essentially just a dump of a question and some code.

Along with the code that you already have, state what specifically you're asking about.

[weary marten]

thank you very much

soo i am doing a challenge but im soo confused on where to start

[robust shore]

Did you understand the example

Do you understand what you need to do

what part are you confused about

[weary marten]

i do but wha tim confused about is trying to start it

i already took teh examples

[robust shore]

right

You need to take the seed phrase and hash it until it gives you the hash that you are looking for

[weary marten]

ohhh okay thanks and this is the seed phrase

which is

654e1c2ac6312d8c6441282f155c8ce9

[weary marten]

and how do i hash it thank you for helping for me

[robust shore]

look at the example

[weary marten]

thank you so i have to put the seed phrase into this 654e1c2ac6312d8c6441282f155c8ce9

[robust shore]

into?

[weary marten]

where its says hello world

[weary marten]

like how do i hash the seed phrase until i get it by coding it which im getting a little confused

[robust shore]

you need to write a loop

and check each time if the hash is what it is supposed to be

if not, keep hashing

[weary marten]

ok i will attempt to do it thank you and i will come back

https://stackoverflow.com/questions/47123809/hashing-a-hash-in-a-while-loop

i seen this code

can i use it

and will it work

with what im doing

[robust shore]

yeah is it not working?

I think it should work

[weary marten]

yeah its working its going too fast

and do i just have to find the same hash

[robust shore]

You have to find the hash that hashes to the challenge hash

make sure your seed is right

seed phrase or whatever its called

[weary marten]

thank you for helping me

and

so i will need find

c89aa2ffb9edcc6604005196b5f0e0e4

this in the terminal then i will finish the challenge

@robust shore you still here

[robust shore]

yeah

[weary marten]

so do i just have to find c89aa2ffb9edcc6604005196b5f0e0e4 in the terminal and i will be finished

[robust shore]

the hash before the one that gives c89aa2ffb9edcc6604005196b5f0e0e4

so once you get c89aa2ffb9edcc6604005196b5f0e0e4 it's the one before it what you're looking for

but you should write the code to get this for you, rather than searching through the terminal

[weary marten]

okay so i will need to make a code that will target c89

and then get the hash before it

and then i will be finished

[weary marten]

@robust shore sorry for tagging you again this is the last one sooo just get the hash before it and i will be done and then get it to target the hash

[weary marten]
