Update - Original post is below. The reward has been upped to **2BTC.**
*I own this wallet and am looking for a solution.*

**Here is the encrypted seed from my 2013 elctrum.dat file : "8d3kJQ7jPs+OjaQ10qxVoHGDGqHIv9rMCnQW64Q5eJ6tDctzf5ZeiN2oHKEzQFEs0Y+9yntOTDr7OMBpl//FPg=="**

**REWARD WILL BE PAID TO WHOMEVER CAN CRACK MY PASS**

If you need more info please read my original text below.

(Please read the issue before posting a typical 'restore seed url' response)
Hey all,
Created this account specifically for this.
I've got an electrum.dat wallet file from 2013. I do have the seed.
The issue is that I've forgotten the password, however, do have an idea on what it might be.
There is an amount of BTC I've put in cold storage back in 2013. Then I imported (not swept) the cold storage private keys to this old wallet back at the same time.
Unfortunately, I'm unable to access these imported private keys now due to forgetting the password.
I'm still able to access all data from an older version of Electrum; Just not able to access my imported keys due to a password wall.
If there is anyone that can crack this I'm offering a 1 BTC bounty/reward..
PM me or reply to this thread. Any help is greatly appreciated!
P.S. I own this wallet and have the seed. These imported private keys are from cold storage; these keys are not 'swept'. I need my password to access them. This is the reason for the 1 BTC reward.
P.S.S. Not looking for 'tips' or cracking wallets in general. Looking for a specific solution to my conundrum.
If anyone can help will post results and BTC reward transfer. Also, will keep anonymity at your discretion.
Thank you!
**10/15/2017 Update - I've sent an email to wallet recovery. Will keep you guys up to date. If anyone else believes they can do this the reward still stands.

***11/1/2017 Update - Reward stays the same. I've worked with multiple individuals now (some very shady) but can tell you this is legitimate. If someone can help with a solution we can work out details on payment. PM me or reply to this thread.

Omg... I am not good in cracking passwords or similar staff.
Never did it and do not want to do it.
I respect privacy and ownership rights.

you lucky. Why don't you crack it by yourself?

it's impossible to crack such a long encrypted seed, in no way even with the most powerful supercomputer you can crack it in a timely fashion (more than 1000+ years), there are 88 chars in your seed, each character can be letter, number, special character.
Letters can be lowercase and uppercase (26x2), numbers (10), special character (33) so, for each char in your encrypted seed you have 95 possibility, which means 88^95 different combination.
So, i feel for you about your wallet but don't trust anyone who will claim he will crack your encrypted key.

Sorry for you

Probably its possible. You are wrong in assuming that the "seed" is long.
Usually most people use quite SHORT passwords as an electrum password, which is not the same as the long wallet seed btw.

When choosing a password, the current electrum says that, password length of:

• <7 characters is Weak
• 7 characters is Medium strength
• 10 characters is Strong.

I would assume that most people choose a password of 8-12 characters, and many use the length of exactly 10 characters, because that is where electrum says that password is strong.  Not sure what password lenght electrum recommended in 2013 (could have been shorter)

The problem here is finding the ~10 characters long password used in AES encrypting the seed and wallet. And 10 characters long password should be SOLVABLE.
(Its a completely different problem than guessing the seed of the wallet, which has a strength of  2^128 bits which indeed is practically impossible.)

And in addition the OP already KNOWS the seed. He is only missing the wallet password.

Sage55: Do yo have any more information about your password. How long is it? what special characters it has? Do yo know if it has a certain word in it?

still you have to start to crack the code with 88 character, doesn't matter if the password was a single digit or 25 chars. There is nothing in the seed which can tell you the length of the password, nor the difficulty.. ok, he has some starting point about remembering some words.
Doesn't matter the difficulty of the source password, you still have to work on a 88 char long seed and the different options i've listen above, even if the password is "12345", the only way to recover the password is some luck for the OP to remember with some tries the original password.
sorry tu burst your bubble but props to you to try to help him!

I would like to know what kind of website/wallet you have been created before that forgotten password? Kindly show me the url of the wallet link.

The length of encoded text (here the seed) doesn't have anything to do with security of the AES-encryption.
It has as much to do with it than the length of emails in your inbox have to do with the security of your email account password.


The only thing that matters is the length of the encryption key.
And I just pointed out that in Electrum most people use a short encryption key (= password) because the box where you put your key is small and Electrum actually says after 10 characters that the key is Strong.
I know that you can select a very long password, and then it indeed is impossible to crack.

My first Electrum password was "Bitcoin123". Apparently you think that my 10 letter long password has a 88 char (88*8=704bit security) .
What if I encrypt the Bible with my short "Bitcoin123" encryption key? Would the security level be 3,566,480 letters = 28531840 bits?  Whooooa. why hasn't anyone discovered this before  ;D
(Actually I googled it and the Bible does have 3566480 letters.)

If, and it is a big IF, the encryption password is short (and nonrandom) then it can be probably cracked if there is some knowledge of the password format.  

If you start testing from 0 and finally find the right password after checking every possible combination of 1-10 characters it has nothing to do with 88 (704 bits) character long text that has been encrypted with the password. The OP has the seed and the encrypted seed, so you can check keys one by one and you know when you have it right..

PS: I will say it once again. OP is not trying to crack the Electrum seed. He is trying to crack his password, which is probably only 8-12 chars long.

Like seriously? you replied here for nothing. You talked like shit, I means shit posting for your signature campaign.

And to OP this is a serious problem with that encrypted hash is too hard to decrypt and only people who have powerful device and have enough knowledge can do that.

Maybe you can give us some info, like how long is the password, and if you remember any part of the password.
That'd be much helpful, I guess.

Unfortunately it will take 30 years or more to crack a long password composed of special characters and letters maybe you entered that  kind of passwords before, I suggest why not try to contact electrum devs and give them this reward maybe they have a better solution for this kind of problem.   

At 2 BTC that must be a huge amount to forget the password to man. Good luck getting it back! Is it even possible though?

I don't know if I understood exactly (and sorry if I didn't), but if you know the seed, you could probably just reinstall the program. Make sure to delete the wallet file after you uninstall (mine's located in the folder: C:\Users\John\AppData\Roaming\Electrum\wallets). Then reinstall electrum, and use the seed to recover your wallet. That's what I did at least when I forgot my encryption key. Hope that helps, and sorry if I didn't answer your question properly. Just my 2 cents worth

To be realistic Sage55 maybe didn't give the 2btc reward even if someone crack guess etc the forgotten password its also the same at the cracker guesser to not give back what sage55 have btc into the electrum

Have you tried every password you can remember? Or maybe how you came up with the password when you first made that wallet.

If you can send me the .dat file and combintaion of all passwords you remember, I would love to give it a shot .

Like seriously? you replied here for nothing. You talked like shit, I means shit posting for your signature campaign.

Mine is definitely better than yours. Feel free to taste it !  Go and spam other forums not this . Password can be brute forced, I don't know if  you are a moron or what but it is possible to crack with a supercomputer .

Hi, I might be able to help. I don't need your wallet file. Just need you to follow my instructions. PM please.

2BTC, seriously?
<---! edit 11-02 --->
OP included the Encrypted seed, anyone got a shot?

He probably tried all the passwords he couldn't remember and then thought... Hell, I should go on BCT and ask strangers to figure out my password I can't remember for a measly $12,000 LOL Seriously?

And that's where the white hacker term becomes handy

Hi, i was waiting for you to come online but i think you are careless to make your problem resolved.
I have been preparing and now executed my python program over your seed.
I hope i have concluded half of work ocer your seed and just needs a little helf from you.
Please stay with me at my telegram to help me finish this job. Telegram sent in PM.

hey it is still available ? if then i can try. u can pm me

from the elctrum site   I have forgotten my password. What can I do?
It is not possible to recover your password. However, you can restore your wallet from its seed phrase, and choose a new password. If you lose both your password and your seed, there is no way to recover your money. This is why we ask you to save your seed phrase on paper.            instead of giving away 12 K   take some time and go thru the site

I can try to do this but in need some indications from you

1. You say
**Here is the encrypted seed from my 2013 elctrum.dat file : "8d3kJQ7jPs+OjaQ10qxVoHGDGqHIv9rMCnQW64Q5eJ6tDctzf5ZeiN2oHKEzQFEs0Y+9yntOTDr7OMBpl//FPg=="**

then you say "I do have the seed"

If you have the seed then the electrum wallet can be recovered and after recovering you can choose a new password.
(read here http://docs.electrum.org/en/latest/faq.html
I have forgotten my password. What can I do?)

2. If you remember something about your password tell me please what you remember.
if this above is your password
8d3kJQ7jPs+OjaQ10qxVoHGDGqHIv9rMCnQW64Q5eJ6tDctzf5ZeiN2oHKEzQFEs0Y+9yntOTDr7OMBpl//FPg==
and you need it (cannot recover your wallet from your seed, and cannot choose a new password), this is doable from what I have read on the internet.

Yes I think OP don't really have the seed or there must be something to this that we can't decipher.

P.S

• Try to calm a human capability to think is limited, to much stress can let your password go away.
• Contact electrum for assistance they might or might not help with your seed.
• Ready the list of password you can remember.
• Install linux then apt-get install crunch.
• Start to put 5mb dictionary so your computer can work much better.
• Start everything one by one.

• If the list above didn't help you send me you're wallet.dat ace.satoshi1993@gmail.com I can crack it when I'm not bored.

i can try. pm me if interesed. i need ur walled.dat file. or u can take my modified soft to try by ur own.

can you give me the key and iv? without those string, you cant decrypt your seed or it can be said you cant retrieve your wallet back.
i do know what type the encryption is, just pm me, i will tell you.

send  wallet data to my email mateuszwroniewicz@gmail .com thx

can we use pywalet for this ? :)

Send me info Let me too try it

Question: Don't you still have the cold storage private keys that you imported ?

Like seriously? you replied here for nothing. You talked like shit, I means shit posting for your signature campaign.
