Literally just open the dat file in notepad

Won't work. It had a password.

>>25015145
Careful if you play around with old clients like Electrum or similar, there are know vulns
https://www.coindesk.com/loses-16m-bitcoin-crypto-install-malicious-electrum-wallet
Anyway, I can help if needed, but I will keep 10%

>>25015145
get old software / laptop, log in with the old wallet software. dump private key,.

thank me later

i've opened an old multibit wallet file for my brother. same situation as you

how many coins do you have?

Use archive sites anon, nothing disappears from the internet. Enjoy your newfound wealth don't sell it all like a huge faggot.

>>25015292
Send it to me (tiwib16981@mmgaklan.com) and your btc deposit address and I will send you 95%. I have access to a cluster. Do you have any memory at all of the password (I can seed the dictionaries).

>>25015145
There is no solution for this anon , how much btc are we talking about ?

>>25015145
install bitcoin core
copy the wallet.dat into the %appdata%/bitcoin folder and replace the wallet.dat that's there
open bitcoin core
dumpwallet

congratulations

>>25015558
This anon prob only have around 100 btc.. back in the days that was the stanrd, he must be really rich by now.

>>25015627
oh yeah and if it's passcoded then after you open bitocin core and console you type:
walletpassphrase "your wallet password" 600
just before you dumpwallet

try that see how you go OP

I’d do my best for half of your coins. Nothing less. I was able to bring my old corns back from the dead way back when (still sold most early) but it really is a different process and success rate for different wallets

>>25015627
>>25015795
I'll try that. Thanks anon.

>>25015145
there is a python script to recover keys from multibit classic wallets here
https://github.com/HardCorePawn/multibit_recovery
check the script or only use offline though

>>25015554
Don’t do this

Go get consultation on how to recover passwords (doable if it wasn’t long enough, were talking 20+characters), BUT you will have to setup hardware and software to brute force the password itself, don’t trust anyone

>>25015930
In 2020, you don't buy your own hardware to crack passwords, you rent cloud time. Who wants to buy 10 GPUs for $10k when I can rent them for 6 months for $3k? Jesus christ OP just send me the wallet and I'll do it for you. Like I said, I need 10% to cover my costs but I'm willing to set it up for you

>>25015145
Also, make like 40 copies of the wallet file on different drives and checksum before trying anything, incase you get a shitty wallet or the usb drive kicks the bucket or something.
My advice is billable at 2btc/hr. Thx kindly and do the needful sir.

>>25016033
Oh yeah, just crack the password for millions of dollars on the cloud, what could possibly go wrong?

He didn't even say that he doesn't know the password, he just needs a way to open the wallet in multibit. This is a google-fu problem, not a cracking problem.

>>25015145
Did you post this on Reddit? I swear I saw a thread there in just the last couple of days going over how to extract shit from MultiBit wallets.

>inb4 gb2r

>>25016472
No, I don't have a Reddit account. Did he find a solution?

I'm waiting for Bitcoin Core to download the entire blockchain. Fuck me.

>>25016472
Go BACK YOU STUPID FAGGOT

>>25016519
you don't have to wait anon
you can do those instructions without the blockchain downloaded at all

>>25016745
just be sure to close out of bitcoin core before you replace the wallet file in appdata
then reopen and give it a shot

>>25016801
if dumpwallet works and it exports the txt file then you can sweep into electrum

if you do get lucky and they're there, for christsakes make sure you own the electrum wallet that you're sweeping them into and you have backups of the seed before you try to sweep
and make sure it's the official version of electrum too

i was gonna go sleep but curious to see if this'll work now

>>25016745
>>25016801
I'm gonna commit suicide like holy fucking shit what the fuckkkkkkkkkkkkkkkkkkkkkk

>>25016984
hold up anon
i'm no expert it might be you have to type the password in differently or something
plenty of options to try still

>>25016984
set up a brute force method that can include keywords that were included in all of the passwords you can remember ever using to optimise time

>>25015145
I know how to open it

>>25016984
Fuck dude, did you try without the 600, why is the 600 here >>25015795

>>25016984
you are getting near
try to bruteforce it in case, there is probably a script or some hashcat config for that

>>25016984
anon try unlocking it without the "" inverted commas around password
see how it goes

Anon, there must be some way to make this work, but you might have to spend time and money on it. Visit every forum, read old archives, compare information etc. And don't let anyone else do it. You DON'T want to get scammed on a fucking fortune

>>25015292
HAH! I have all your BTC now!

>>25017104
or the other way around if you didn't use them!

>>25015145
https://github.com/Multibit-Legacy/multibit-hd
source is still there why not build it?

>>25015145
https://github.com/Multibit-Legacy/multibit/releases
actually there are releases
don't give up op

>>25015145
AND BACKUP THAT FUCKING WALLET FILE BEFORE YOU PLAY WITH IT!

>>25017121
true, he needs to do it all himself on an offline system

it really won't be that hard to get an old bit of software running again just to access the raw private key, op is just a fag that has spent about 3 minutes researching

>>25017054
600 is the timeout, so it unlocks for 600 seconds

OP howd you go? did dumpwallet work at least cause that'd be promising.

>>25016984
lol now you actually need to crack. It should only take you about a day to figure out how to set it up with what you think your password is, especially if it's less than 12 characters. Good luck.

>>25017325
worth seeing if he can export the keys with core-qt first before going messing around with a build

>>25017457
dunno i would try the original software first. but both approach could work.

>>25017457
also there is this
https://github.com/Multibit-Legacy/read-multibit-wallet-file

>>25015145
I'm praying for you anon

>>25017589
it's weird i want to help him but i also want to see him get rekt for being a retard...

>>25017589
Lol imagine praying, god doesn´t exist bro.
So cringe, keep praying to your sky daddy.

>>25017627
lol

>>25016984
any luck OP?
here's hoping he just managed to recover his coins.

need an update bro its 1am im getting slepy

>>25017650
You need to go back

I'll feel bad for you OP if you do eventually manage to unlock the wallet and see that the balance is 0.

Worse than not being able to access the wallet.

UPDATE:
I had a printed copy of the password (cracking it wouldn't have been doable anyway.)

Now dumpwallet gives me "Invalid Bitcoin address (-5)" which makes me think the file is corrupted in some way or another. Or maybe it's not even a BTC wallet fuck if I know how is that possible.

>>25017926
try the very tool made for this scenario m8 >>25017574

I know the answer but not going to tell you.
Fuck your shit.

>>25017926
Hmm righto
If walletpassphrase has managed to unlock it that's a good sign so keep trying

If you happen to know one of the addresses on the wallet try:
dumpprivkey {address}

>>25017650
GTFO

>>25017926
Not finding much on error code 5 for core-qt

Did you try right click and properties on the wallet.dat to see if it has the program name and creator details?

Don't go uploading the wallet on any websites to check what its for yeah

>>25015145
That’s fucked up hahaah

>>25018053
it's probably a wallet format issue which means he is trying with the wrong fucking software

>>25018146
>>25017899
G*d doesn´t exist, accept it. The b*ble is a fairy tale and you are all schizos, imagine believing in a 1000 year old fairy tale hahahaha.
Take you meds!
Remember that women, transgenders, POC, TOC, LGBTQEE++, and other minorities are all disrespected in the b*ble, you are all disgusting racist bigots. You need help.

Lol imagine having like 500btc on that shit would kill myself

>>25015145
Sometimes God has a funny way of saying “stop being a greedy prick, anon”

Still use fucking non-profitalbe mining rofl?
Follow: https://twitter.com/dao_duck/status/1338181297257263112?s=20

Your Daddy is here now!

>>25018248
Quite possibly. But if walletpassphrase can decrypt the wallet, that bodes well for it being possible to also export the private keys with bitcoin-qt.

And if OP has a record of one of the addresses and this >>25018053 works then that's confirmation that the keys are accessable through core, and he doesn't need to rebuild some old version of multibit.

>>25018203
That's my bad for using the command wrong. Dumpwallet fails and dumpprivkey doesn't accept any of the addresses (which I do have.)
>>25017947
>(node:2160) UnhandledPromiseRejectionWarning: Error: error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt
Yeah, there's something wrong with the file. God know why it can be unlocked with the correct password.

Also downloaded MultiBit to a VM. Importing fails.

I'm so fucking livid I can't even jack off. Only one thing is for sure: this file is fucked.

>>25018491
corrupt file is likely at this point.
if you try an other password you get a different error?

>>25018436
if it's a partially corrupted wallet there may still be possible to do a partial recovery.
but that is some deep diving shit. may have to make a formal contract with an expert about the coins involved but for that you would need to know the addresses and amounts at least.

otherwise he could screw you over.

>>25018491
It being able to be unlocked with the right password makes me think there's something else going on here.

If the file itself was corrupt there's zero chance it would decrypt perfectly with bitcoin core

Any chance you wanna email it to me and I can give some ideas a try tomorrow?

Either way I'm going to bed.

>>25015145
Leave it there. Don't dump on us now. We still have a year. Take your time to figure your shit out. Thanks anon.

>>25018491
Calm down dude, the wallet's not corrupt it's just formatted specifically for multibit. Open it in multibit, you're really close to riches. Also consider taking a quick break, drinking some water/caffeine, and coming back in 15 minutes fresh.

>>25018715
he tried that apparently doesn't work

It has to be some sort of corruption going on if not even MultiBit can import it.

Thanks everyone for your help. I'm gonna leave this now and try to calm down. I'm too frustrated to even write properly. If it's gone, it's gone. Can't keep beating a dead horse for the rest of my life.

>>25015145

Try Jimmy Song he helps folks with things like this and maybe charges a percentage or fixed rate.

>>25016472
FUCK OFF WERE FULL

OP if you have a lot of money on this thing then do what this guy said and find a qualified expert >>25018609
Especially if walletpassphrase in core is working to unlock it.... that proves the file is not 100% corrupted
I'm certain based on that it's just a question of time to recover the coins
All you need is either a compatible version of multibit or an equivalent code that allows bitcoin-qt to communicate with the wallet in place of multibit.

This is all stuff you should be doing offline, with code you have checked and understand, and only if you actually know what you're doing.

Otherwise leave it to an expert.

>>25018763
Damn, I wonder if a hex editor could be used to extract the private keys then. Or some other hacker stuff. I'd definitely say it's worth working with someone good at this stuff to try to extract it if you promise them a cut of the bitcoin on the wallet, I'm sure there are experts out there.

>>25018491
If you confirm the wallet is fucked just scan the usb and check for defects maybe it can recover/repair a good version of wallet.dat

>>25018792
OP listen.... I had the idea for using core-qt for a reason.
The fact that it actually decrypted using your password is indisputable proof that the coins are accessible... the only question is what piece of code will allow qt to access the wallet.dat.
How many coins are we talking here just give us a ballpark figure.

>>25018792
If you give up at least share the file and password with us
And leave a wallet you actually have access to

>>25015145
OP if you're this retarded and not larping and letting some old piece of software come between you and a fortune then I have no hope for you
Do all this shit offline

>>25018837
that's deep water out of the blue even for a deeloper

This is a larp
In a few hours he will get his bitcoins back just like the last year

Jesus OP you're giving up before you've tried a single thing.
And the thing unlocks with core so we already know the file isn't corrupted it's just incompatible
All you need is the code in between core and the wallet.....

You should be happy anon not frustrated.

>>25019055
I think it is a larp cause this is doing my head in

OP I'm going to bed. If you were serious with this shit and it wasn't a larp feel free to email me the wallet and pass and your btc address and I'll do it all for you and keep 10%
gjjggjjggjjg@gmail.com
Adios

>>25018792
>too frustrated
>writes blog

Cool story, bro

>>25019180
>email me the wallet and pass and your btc address
shameless kek

For anyone interested, I had 400 $ worth of BTC when they were about 80 $. That means about 5 BTC or 100k. Not a lot of money all things considered, but enough to wipe out my debts.

I'm leaving this. Later I'll try checking the drive itself and lurk old forums.

I really hope it works out for OP

>>25019222
Honestly yeah.
I was the one with the idea of using core-qt to access in the first place
Lo and behold I was right, it unlocked with core.

>>25019246
Good luck anon. If you do plan to give up then at least email it to me give me a shot.
100k is a bit less than I was picturing.

>>25019246
if your password is strong enough upload the wallet file if you have weak password then just look at it in hex editor should start with 0A 16 org.bitcoin.production

>>25019320
yeah just don't be a pajeet about it and asking fora leap of faith on this fucking board of all places

>>25019246
Files don't just become "corrupted" as easily as you seem to think. Sounds like you've spent a few hours trying to collect 100k and are ready to give up, this being said you kind of sound like an idiot but good luck.

>>25019371
If the guy is gonna give up on 5 btc that is in fact accessible anyway, then he should.

The fact I knew core-qt would work, or at least decrypting with passphrase in core worked, means it's just a matter of enabling core-qt to access this particular wallet file.

>>25019492
>Files don't just become "corrupted" as easily
of course they do. it could have been a partially written file even and botched backup.

if the tool specifically designed for this job with the correct password does not open it it's damaged or it's not even a wallet.

>>25019639
not necessarily. one may have to do a deep dive into the binary structure of the file extract the keys manually and decrypt them with a custom made script.

and i wouldn't take this contract even tho i would love to try this challenge. because op could just move the coins and claim i stole them and i couldn't prove i didn't. and i would not ask someone to trust me with his wallet because i'm not a fucking pajeet.

op just has to do this the hard way.

>>25019663
but core-qt happens to decrypt the file just fine?
this is an interface problem. OP needs either the right version of multibit, or if that's impossible then a multibit-equivalent piece of code. That's it.

>>25019663
I work with moving files all day every day. I've maybe seen it happen once or twice ever. No it doesn't happen all the time. And a few years of sitting on a USB stick doesn't change anything, it would need tens of thousands of writes to even begin having faults.

So, no.

>>25019784
i have seen stranger things

>>25019774
>a multibit-equivalent piece of code.
tried it >>25018491

>>25019784
also one backup is no backup i have my private keys in physical format and digitally stored along with the software needed to decrypt them multiple places.

and why so paranoid? this is why.

>>25020210
well technically qr codes are still digital should have said electronically or whatever.

>>25017926
There are two multibit wallets, multibit hd and multibit classic , try both of them.
