Trouble decrypting wallet
AsaBarthMaron opened this issue · comments
I have previously had success with this method (#68 (comment)) for decrypting a wallet backup file. However I am now having no luck with a new wallet file.
It is possible I am using the wrong password, but I am getting slightly different error messages when I try any other password, and I think the one I have in mind is in fact correct.
Upon running:
openssl enc -d -aes-256-cbc -md md5 -a -in YOUR-dogecoin-wallet-backup-FILENAME -out dogecoin-wallet-decrypted
With what I think is the correct password, I get:
bad decrypt 4492775020:error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt:evp_enc.c:536:
But when I use literally any other password, I get:
bad decrypt 4591435372:error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt:evp_enc.c:531:
So the first numbers (4492775020, 4591435372) are always different but the last number is always 536 for the 'correct' password but '531' for the 'incorrect' one.
This is on a machine with OpenSSL 1.0.2o
I also tried on a different machine with OpenSSL 1.0.2h and got similar but slightly different error messages
'Correct' password:
bad decrypt 4294956672:error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt:evp_enc.c:534
Any other password:
bad decrypt 4294956672:error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt:evp_enc.c:529:
Again, it's always 534 for the 'correct' one and '529' for any other.
So I am left wondering/unsure if this is an issue with the decryption or password, or worse if the file is corrupted. Thanks for the help!
I'm using the android version and I have a similar situation.
My back up is from 2014.
When I use a random password I get error wallet could not be restored: Could not decrypt bytes. Bad Password?
When I use what I think is the correct password I get "Protocol message contained an invalid tag (zero). Bad Password?
Do I need to use an older version of the wallet or something?

This is a little different from my current problem, but I have had this exact problem in the past and have been able to decrypt it with openssl. I am happy to help walk you through that. You can find my email on my github profile.
I'd really appreciate some help. However, if you don't mind it might be better to comment here so others with the same problem can see?
@AsaBarthMaron Could you post your instructions publicly? I may also have the same issue (backup from 2014 not being able to restore).
@sandman2448 @gilgongo Yes, apologies for the delay!
So first off you just need to have some method of using openssl. If you're on mac or linux it is just a matter of opening the command line. If you're on windows there's a few different ways to get openssl running but the easiest way I found is just to download the git bash.
Once you have that you can go about decrypting the wallet backup file using the command posted here:
openssl enc -d -aes-256-cbc -md md5 -a -in YOUR-dogecoin-wallet-backup-FILENAME -out dogecoin-wallet-decrypted
Though importantly if you're using git bash on windows you will need to append winpty to the beginning:
winpty openssl enc -d -aes-256-cbc -md md5 -a -in YOUR-dogecoin-wallet-backup-FILENAME -out dogecoin-wallet-decrypted
It will then ask you for your encryption password, and save the decrypted file to dogecoin-wallet-decrypted
dogecoin-wallet-decrypted Should look something like:
# KEEP YOUR PRIVATE KEYS SAFE! Anyone who can read this can spend your Bitcoins.
52-CHARACTER-LONG-ALPHANUMERIC 2014-01-20T21:32:56Z
The 52 character long string should start with a 'Q'. If you get to this stage you have completed the hard part and will definitely be able to get your doge!
There are a few methods to import a private key directly, but the one I like is using https://my.dogechain.info/#/overview. There are two methods here. Firstly you can create (or log into an existing) wallet (don't lose the wallet ID and password though haha). Then you can go to 'Import / Export', enter the private key and press 'Import private key'. That should be it! You will then have all your doge in this new wallet. From there you can send it to a new wallet if you'd like with the 'send' option. The second method is to skip the dogechain wallet step and select the 'Redeem paper wallet' option on https://my.dogechain.info/#/overview. Here you will enter the private key directly, and it will then ask you to what public wallet address you want to send the contents of that private key. This will require you to already have another wallet set up elsewhere. I've used both methods successfully.
I also have a reddit post where I explained some of this, albeit probably less thoroughly than I just did here: https://www.reddit.com/r/dogecoin/comments/lkaexc/dogecoin_daily_discussion_feb_15th/gnllm7o/?context=3

Nice! I managed to get my private key! Before I use it to get the coins though, I have two files. One that I've decrypted using your instructions - that was called "Dogecoin Wallet private key backup" (240 bytes). The other is a larger file called "Dogecoin Wallet backup" (32.2Kb) containing 420 lines of text each 77 characters long, apart from the last line ending in "==" which is shorter.
What's that?
@gilgongo Can you give me a little more info? What does the first line of the 240 byte file say? And what letter does the second line start with? (I am assuming there are two lines, as there should be). I believe that file should be the file with your private key, which you should be able to import on dogechain. I am not sure what the second file is, or how you ended up with two files. Did you start with more than one encrypted file? Or did decrypting somehow produce two? (shouldn't be possible)
The 240 byte file is the private key, and decrypted OK with the passphrase I had. I'm just curious what the second file 32.2Kb file is. Maybe it's some transaction data or something? I seem to remember I made the backbup from my phone, so it may be something the app was using. But I guess it does't matter as I've got my private key now :-)
@gilgongo Great, do you know how to go about recovering the doge from that key then?
Yes, as per your instructions, thanks! I tipped you some doge to that address in fact.
hi, I am quite a noob in these area, so can someone help me with this...
what do I have exactly to fill in that following spot in the command: in YOUR-dogecoin-wallet-backup-FILENAME ?
What do I have to fill in myself overhere as a command exactly.'
YOUR-dogecoin-wallet-backup-FILENAME'
That will be the name of the file that is the wallet you want to decrypt. For example, I had a file called "doge-wallet-bkp.dat" but yours might be called something else. In other words its simply the name of the file you have.
Ok thx, I dont have the .dat file thats the problem
I have the encrypted key and the password but don't know how to decrypt it...you have an idea?
OK sure. You just need to follow the instructions given here then: #87 (comment)
Thats the above comment where you need the .dat file for?
Yes, so you need to run than openssl command on your wallet file, basically. So if for example your wallet file is called "doge-backup.dat" then you'd run:
openssl enc -d -aes-256-cbc -md md5 -a -in doge-backup.dat -out dogecoin-wallet-decrypted
Maybe I was not clear in my previous comment...I don't have the .dat file anymore only the encrypted key with pass
Well, the key kinda is the wallet really, so you should be OK. Just try that command on the file you have and see if you get the decrypted plain text file with the 52 character key in it which you can then import it into a wallet (as per those instructions above).
Bumping that thread up because it allowed me to decrypt my 2014 key.
Thanks a lot @AsaBarthMaron

please help me
I have received an email from Dogechain.info to transfer fund last week , when I want to login , when I fill my password , for just one time it send me 2FA code to my email , but it was just one time , the it does not send again , then I see a form that I send my name and city but then I could not login finally
then I wanted to try with 2FA.com application, I had back up file and I restore it to get code, but when I want to login to dogechain.info it does not accept the code that I receive it from 2FA application , and said it is invalid code , and it does not send 2fas code to my email too and I can not login to my account at all.
more over i have a exported encrypted file that I don't know how can I use it :the file start with :
salt(+xTuGfX+WWf/Tzb5AYv1TA==) ......
I send email to block.io but no body answer me.
just in case I create new wallet in dogechain but in that one I receive the code in my new email for new wallet
please help me

@hastiAu Dogechain.info changed its platform and encryption method again. you can reach Stephen from www.btc2doge.com He helped me before. good luck.
@doge2021
how can I trust him? he needs my personal information to recover my dogecoin
@doge2021 how can I trust him? he needs my personal information to recover my dogecoin
@hastiAu it depends. some case need the wallet info, while other problems may not need the wallet info. in the past, for 2fa issue, i only need signed a form and he resolved my problem. but now, seems dogechain.info changed its platform and old method not work any more. i think your case is different. you may need provide them the file you mentioned start with: salt(+xTuGfX+WWf/Tzb5AYv1TA==) ......
this maybe the last hope as i know many guys get their dogecoin locked by dogechain.info due to this issue. good luck
my backup is some text that I have saved before on a text file , because I have created a wallet just on the Dogechain.info website
and after this code I see this error:
openssl enc -aes-256-cbc -base64 -pass pass:149149ssS -d -p -in ~/c/Users/Hasti/Desktop/key.txt -out enc.txt Can't open "C:/Users/Hasti/c/Users/Hasti/Desktop/key.txt" for reading, No such file or directory 403E0000:error:80000003:system library:BIO_new_file:No such process:../openssl-3.1.4/crypto/bio/bss_file.c:67:calling fopen(C:/Users/Hasti/c/Users/Hasti/Desktop/key.txt, r) 403E0000:error:10000080:BIO routines:BIO_new_file:no such file:../openssl-3.1.4/crypto/bio/bss_file.c:75:
Are you using Cygwin? There's some path problem. You're giving it ~/c/Users/Hasti/Desktop/key.txt but openssl is getting "C:/Users/Hasti/c/Users/Hasti/Desktop/key.txt" so it can't find that.
Maybe try in ~/Users/Hasti/Desktop/key.txt or just cd to Desktop and use -in ./key.txt
@gilgongo no I use Git Bash. but none of these path does not work again and see this same error.
but when cd desktop and again run that code, nothings happened
And when you do an ls can you can see key.txt or key2.txt ?
BTW if the command completed successfully you may not see any output - it just creates the file.
