Line-length exception....

[onis_uk]

Hi all, I've done a ton of reading and watched videos but I cant figure this out, So I joined the forums for some pobbile help! 
Right this is where im at...

I've got a Musicoin wallet .json file I cannot remember the password to.

I ran the file through the ethereum2john.py script and it spat out my hash. 

I shows the first part as $ethereum$s*262144*8*1* so I think this is a SCRYPT v3 which is gpu resistant.

I think I roughly know the password so was hoping to use a mask to help solve it.

I wanted to start out buy running a standard dictionary attack at it to see if hashcat worked and I got this....

C:\hashcat>hashcat64 -m 15700 -a 0 -w 3 .\hashes\music.txt .\wordlists\john.txt
hashcat (v4.0.1) starting...

any pointer would be great.

You need to make sure that the hash file (the first file that you specified, e.g. .\hashes\music.txt) does contain the hash that you extracted by ethereum2john.py.

I think you didn't store the output of ethereum2john.py to the file. The content of the hash file must look similar to the hashes that you can find here: https://hashcat.net/wiki/example_hashes (search for 15700)

yep its exactly the same format...... as the text shown next to 15700..?

[undeath]

maybe a BOM problem? Or even a totally weird encoding like UTF16?

[philsmd]

Exactly. As undeath already pointed out there is a problem with the format or encoding of your hash file, it could be one of these:
1. wrong path to the actual "hash" (you point to the original wallet file instead of the extracted hash?)
2. you extracted the "hash" with powershell or manually set the default character encoding of your shell to something different than ascii/utf8 (maybe utf16 is used)
3. for some reason extra BOM characters were added to the file
etc

It's very clear from your output above:

Code:

Hashfile '.\hashes\music.txt' on line 1 ( ■$): Line-length exception
Hashfile '.\hashes\music.txt' on line 2 (): Line-length exception
Hashfile '.\hashes\music.txt' on line 3 (): Line-length exception
Hashfile '.\hashes\music.txt' on line 4 (): Line-length exception

that hashcat discovered 4 lines within the file .\hashes\music.txt . This shouldn't be the case with a correctly formatted "hash" file extracted by ethereum2john.py by using python 2.7 on the cmd (not powershell with special character encoding).

I would suggest that you open the file .\hashes\music.txt in a text editor.
Copy-paste everything starting from the $ethereum$ signature to the end of the line.
Insert it into a new file and make sure that you safe it with ASCII character encoding.

Ok so things to double check......... should the hash be on a single line in the .text document?
I have a hash that is 1 line 215 char long.
I had originally set it out like is seen on the example hashes page?!

I cannot see an ASCII option in notepad++ or ven just normal notepad.
just ANSI, UTF8, UTF8 BOM etc....

Hi there!
I also have Musicoin wallet file with 62 char ciphertext

Code:

{  
  "address":"#SOMETEXT#",
  "crypto":{  
     "cipher":"aes-128-ctr",
     "ciphertext":"2151cd3f36c3c5ce075aceda6bbdd495af3b8001f4571dc4245ae0916f2253",
     "cipherparams":{  
        "iv":"#SOMETEXT#"
     },
     "kdf":"scrypt",
     "kdfparams":{  
        "dklen":32,
        "n":262144,
        "p":1,
        "r":8,
        "salt":"#SOMETEXT#"
     },
     "mac":"#SOMETEXT#"
  },
  "id":"#SOMETEXT#",
  "version":3
}

mb its something like here ? https://github.com/paritytech/parity/issues/2263

[onis_uk]

Yes if i open my key file it has that exact same format.

Did you get it to run?

for 62 char ciphertext i get



if ciphertext 64 char - all is OK (except speed :p)

[onis_uk]

still says no hashes loaded tho?
