where do you guys redeem ETH private key ?
I would try Coinomi for this.
i did not trust any downloading wallet.

only bitcoin core .
Lol Cheesy
I can guarantee you won't be able to redeem an Ethereum private key in Bitcoin Core.

can i ask where ?

Bitcoin Core is for bitcoins... please try to google yourself because some of your questions makes me think you are playing with us or you are extremely lazy and want to have answer and solution for everything without any effort.
https://ethereum.org/en/wallets/

If you want safe solution for many coins - buy hardware wallet.
If you do not care at all - create account on blockchain.com
If you are somewhere in the middle and want one wallet for 'everything' - try for example Mycelium
Otherwise you will need to install separate application for each coin, like Electrum for bitcoins, ElectronCash for bitcoin cash, etc.

i did not trust any downloading wallet.
 

Then buy Trezor
1823  Bitcoin / Bitcoin Technical Support / Re: hello every one i need help with old passphrase on: August 21, 2020, 04:09:20 PM
It happens.
Maybe delete bitcoin data folder (downloaded blockchain) and start again, to start from the beginning.
I read about issue with Mac computers, where BitcoinCore start took lot of time because it was calculating some blocks already downloaded - and with slow disk it may take some time.
1824  Bitcoin / Bitcoin Technical Support / Re: hello every one i need help with old passphrase on: August 21, 2020, 03:55:23 PM
Bitcoin Core expects to have the whole blockchain downloaded - so it may confirm the state of wallet. Do not waste your time - extract keys and import to another program - Electrum or other.
Depending of your connection speed and your hard disk (normal or ssd) you may need to wait some time for the whole blockchain to download, maybe day, maybe 2, maybe more.
1825  Bitcoin / Bitcoin Technical Support / Re: hello every one i need help with old passphrase on: August 21, 2020, 12:49:04 PM
And you may use this tool: https://learnmeabitcoin.com/technical/wif
to convert private key to WIF (compressed or not) which you may import into bitcoin wallet.

I have no idea if those coins belong to the actual physical coins
I could only find addresses for Series 1 and Series 4: none of those addresses have been redeemed recently.

Quote
Looking at the pictures the OP has posted, I'm a bit more convinced that he might have access to the creators hard disk.
We never got clear what's under the "Redeem" QR, but it's starting to make sense if that's a BIP38 encrypted private key.
However, this is what OP said about it:
the QR show only the btc address thats the problem and only with 6 word key to redeem and collect .
That wouldn't explain why he removed the Redeem QR. Unless it was blank already.

if you know who is the owner for that HHD i can help him and take my 30% of what he lost

As you wrote few days ago, he just lost 35BTC...

For the rest, I think it is all you may restore. Files you have are information he sent to buyers of his coins. I would be very surprised if he kept private key AND passphrase on his computer - it would mean that it is difficult to trust him as a seller, because he would be able to get buyer's BTC any moment. So, I think private key were only on the coins and he kept passphrases together with addresses, as a extra info which he had to give to buyer.
Maybe, maybe, you will find something else - some wallets (.dat files) etc, but at least you know exactly who is the owner of the files and whom money you take.

Of course, what did you expect?
By default stride = 1, which means you check numbers ...,3,4,5,6,7.....
but if you specify stride 5, program checks 5,10,15,20,25... Why you expect to have number 9 or 11 checked?
If your public key is generated from number 20, it will be found, if from 21 - not. It is obvious.
1828  Bitcoin / Development & Technical Discussion / Re: BitCrack - A tool for brute-forcing private keys on: August 20, 2020, 05:53:21 PM
Everyone knows that bitcrack only goes by consecutive keys.

Not really. You may specify your own 'distance' between key.
For example:
Code:
--stride F4240
will do 1000000 keys long 'jump' between tries.


That's still consecutive not random

how you are calculating --stride F4240 = 1m
how about for 1 billion or for 50billion? please tell me how to calculate any guide

1000000000 = 3B9ACA00
50000000000 = BA43B7400
1829  Bitcoin / Bitcoin Technical Support / Re: hello every one i need help with old passphrase on: August 20, 2020, 05:13:35 PM
it says the seeds will give me the 6P number

but where can i find it if the web i need to Using http://bit2factor.org  is close ?


try https://www.bitaddress.org/

or maybe download this repository (if it is the archive of bit2factor.org)
https://github.com/mannkind/bit2factor.org




1830  Bitcoin / Bitcoin Technical Support / Re: hello every one i need help with old passphrase on: August 20, 2020, 02:18:10 PM

2. Read and copy QR code of the printed paper under the hologram, this is the encrypted private key of your coin (begin with ‘6P’).



Exactly.

You have address, you have passphrase - all you miss is the encrypted private key.
Keys were written on the coins...
Now you know what you are looking for - maybe there is backup - list of "6P..." texts.
1831  Bitcoin / Bitcoin Technical Support / Re: hello every one i need help with old passphrase on: August 19, 2020, 04:37:05 PM
and i use only the app not the web for blockchain

i dont know how to and where i can use the seeds in the web wallet ?



https://login.blockchain.com/#/recover

and I think this is for old seeds: https://login.blockchain.com/wallet/forgot-password

1832  Bitcoin / Bitcoin Technical Support / Re: hello every one i need help with old passphrase on: August 19, 2020, 03:10:18 PM
You may try some of these (some old) wallets - read explanation how it works:
https://walletsrecovery.org/

I think some people already had similar issue, there is still a chance the seeds are for blockchain:
https://bitcoin.stackexchange.com/questions/63697/why-is-this-12-word-mnemonic-deemed-invalid-by-multiple-wallets

Did you try Exodus?

https://bitcoin.stackexchange.com/questions/78620/wallets-with-bip44-support

BTW, if you know address, you my try to use this tool, to see if seed is 'broken' and could be repaired:

1833  Bitcoin / Bitcoin Technical Support / Re: hello every one i need help with old passphrase on: August 19, 2020, 02:07:36 PM
There is something I do not understand... Aren't 12 word seed split into 2?
Or you send us wrong screenshots
in both files you have this same content:

1834  Bitcoin / Bitcoin Technical Support / Re: hello every one i need help with old passphrase on: August 19, 2020, 12:43:58 PM
Do you have any information which could be used as a 'salt' on this page?
https://brainwallet.io/
In a similar line of thinking... is there any sort of "email" that might be associated with these 6 word passphrases that you could try using with Warp Wallet (https://keybase.io/warp)? Huh

Yes, I have checked WARP too, some other 'brain wallet generator pages' too. I think someone used seed known to him (email, birth date, name, city) and then just distinguished addresses by passphrase.

Kuw: could you post again screenshot of the file? 2 images you send in the past are now removed. Do not you see anything like a 'seed' 'salt' 'root' I do not know --- something common to all the addresses?
1835  Bitcoin / Bitcoin Technical Support / Re: How to dump all private keys from wallet.dat ? on: August 19, 2020, 12:24:20 PM
I want to know if want to make any specific wallet address as dump key how to do that

Hello,

There's a C implementation at https://github.com/bitcoin-core/secp256k1 . I need help on code to compute basic operations i.e point addition, double and multiplication in C language.

The inputs / outputs must be in the form of hex. A little performance drop is acceptable.

Bounty at 12345E6kXHSKsrWJ3VLa4QBRF6UWraawU4 .
Thank you.

Maybe take a look at this project, in this class you have everything needed:

Why not load hardware wallet with your seed + add extra password + add pin?

Read the OP, and you'll know why.
This simply does not work the way OP wants/needs it.

It is about collaborated access to the funds, not multiple layers of security.

Exactly - you will need 3 parts to access the balance. Of course there is always a question which part should be given to someone or left at notary.
Another question is - what if one of 'owners' die first (or lost his 'piece') and if others will be able to access wallet at all.

How many 'groups' you want to create? 3?

blockchain.com used 6 words recovery phrases for old wallets, but I am not sure about the dictionary.
