Title: Getting bitcoin address from blockchain.info wallet.aes.json file
Post by: mforno on October 09, 2018, 11:47:36 AM
Does anyone know how I can find out how much I have in my old blockchain.info wallet?
I have the wallet.aes.json backed up but dont know the password to login.

Is there a way to find out the bitcoin receiving address to see how much is in the account?

Cheers

If you have a clue what your password might be or know some specific characteristics of your password you might try out btcrecover (https://github.com/gurnec/btcrecover).
But you need a pretty decent clue on what it might be.

For example, can you limit the amount of characters it had (e.g. 6 to 8 ) ?
Can you tell for sure which symbols you have (or have not) used ?
Do you regularly use any specific sequence (e.g. always 123 at the end) ?

All of these things are helping to decrease the search space. If you can guess it good enough, you can bruteforce it.

Yes, I setup up btcrecover lastnight only to discover that I had to know part of the password to start with.
Is there a way to just bruteforce the password without knowing any part of it or will that just take too much time to compute?

Try put this in .txt that used for password list
Code:
0
1
2
3
. << - - - until
9
a
b
c
d
. << - - - until
z
However, it will take a lot of time to brute forcing it except you're lucky or the password is pretty easy, it can take about some years or probably hundred years. If you think the password only number, then you don't need to write the alphabet, and vice versa.

Thanks for this!
Luckily I managed to guess the password :)
