How about this: "do this offline!!"?
Sounds great! I know the old one probably would be good enough for most people but somehow you will always run into a comparateur assurance chien few slower ones like me 
Topic: [overview] Recover Bitcoin from any old storage format - page 2. (Read 8583 times)
thanks. in case it helps anyone, it turns out that the old blockchain.info wallets encode the keys as BASE58 (RAW).
So just convert that from base58 to hex through any means and then generate a WIF like through bitaddress.org
So just convert that from base58 to hex through any means and then generate a WIF like through bitaddress.org
hex comes out as 64 chars starting with f5: (listed in pairs, though only 64 chars without trailing zeros - e.g. counting 5 instead of 05)
I have no experience personal recovering old wallets from blockchain.info, but if you ended up with a 64 character HEX, you might be on to something:Private Key Hexadecimal (64 characters [0-9A-F]) (less common).
Example: CA9A061710B8BC582E1B8BB60D0F3F2751791888AB5C18737620087ABDF74A05
I'd try to enter this on the Wallet Details tab on an offline and air-gapped downloaded version of Bitaddress.org. Example: CA9A061710B8BC582E1B8BB60D0F3F2751791888AB5C18737620087ABDF74A05
Trying to recover from an old blockchain.info (wallet.json.aes).
Know the password, managed to extract a 44 CHAR string as the private key.
But not clear to me this is the key base64 encoded - as a text decoding comes up as a mess, and hex comes out as 64 chars starting with f5: (listed in pairs, though only 64 chars without trailing zeros - e.g. counting 5 instead of 05)
Anyone have any idea what this is, and how I can convert this to a WIF?
Thanks

Just leaving this here:
.key extension was most commonly used with Multibit.
I think you should redirect people to blockstack_recover: Extract private keys from blockstack-client wallets instead of that topic.
I've added the link, I'll leave it to the reader to If you quote the entire OP, your entry will be deleted.
... would it be possible to put all above into a windows 10 executable which performs a low level scan of the local drive/s, then displays possible files with a % of certainty based on the details found above? while you are building it, perhaps you can also scan for privkeys and anything else bitcoin useful, add in a checkit live switch on the blockchain for possible value. I'll buy a copy and be the first customer!
Bump with a new storage format added:
Blockstack
If you have Bitcoin in a CLI Blockstack node, read this topic.

If you don't have any other instance running, what version of bitcoin core do you have installed ?
And where did you download it from ?
Why do I have these files and are they related to BTC that I may have mined?
"Chainstate" and "blocks" are part of Bitcoin Core, but have nothing to do with your own wallet. The only old file that matters is your wallet.dat.That's what I thought but was hoping wasn't the case. Don't think I have any hidden treasure but I'll now try and get Bitcoin Core installed and check this way to be sure....
Thanks for your help.

No luck unfortunately??? Anti-virus maybe???
In my original Bitcoin folder, I have a folder called 'Chainstate' and contains numbered files (microsoft serialised certificate store). When I enter the number into the blockchain explorer it appears that there are block numbers containing transaction details. Why do I have these files and are they related to BTC that I may have mined?
I also have a 'Blocks' folder with BLK and REV .dat files??

I'm happy I have taken the correct precautions but was trying to avoid a full Bitcoin Core download and sync as I don't have enough room on my laptop to sync the blockchain.
You can use pruning which then only keeps the last few blocks to maintain a maximum storage capacity of X MB (free to choose; minimum 500 MB iirc).
I'm not sure if I need to sync the whole lot as these would have been mined very early on.
You only need to sync until the date you are sure that no transaction happened after that one.
I'm also having trouble installing Bitcoin Core on my laptop for some reason?
What exactly is the issue?
A little bit more information including your OS and any error messages you are facing would be helpful.

Just syncing up to 2010 is enough to see all changes made before that year. If funds show up, you can check the address on Blockchair.com or using a list of all funded Bitcoin addresses to get the current value.

Yes, but you can prune it to save the storage space, though you'll still take some time to synchronize. If you are absolutely sure you don't have any transactions after a certain timeframe, you can wait until Bitcoin Core synchronizes until that period of time and determine which addresses have Bitcoins. You can dumpwallet and import the addresses into a SPV wallet like Electrum. What errors are you having?
I believe Bitcoin-QT became Bitcoin Core around 5-6 years ago???

I have found the wallet.dat file, used the GitHub Wallet-Key-Tool to extract the Keys and then imported all 101 addresses into a Blockchain wallet with all having a 0 BTC balance.
I don't know that tool, so I can only hope you took precautions (such as running it on an air-gapped offline PC). Why didn't you just install Bitcoin Core after making a few backups of your wallet.dat? Or even better: install Bitcoin Core first, let it sync the first few years (that's fast), then add your old wallet.dat after you take the PC offline to prevent any malware attack.I also hope you didn't import the private keys but only the addresses into an online wallet. If you mined a block back in the days, each block would make you a millionaire now, so you're risking if you expose private keys to a hot wallet.

The strange thing is that within the Bitcoin folder, I have Block folders with transaction numbers and full transaction details and some of the addresses still contain mined BTC. Why do I have these transaction details if it wasn't my computer or wallet that mined?
I wasn't using Bitcoin around that time so I don't know what files Bitcoin-qt used to write. I've never heard of Bitcoin-qt by itself storing keys anywhere else than in wallet.dat. Jump to:
