does PYwallet extract a potential wallet.dat file from the hard drive? (Thus altering the data on the original hard drive) or does it simply copy( duplicate the wallet.dat file data)? (leaving the original hard drive as it was before the scan)
It simply reads and copies the data... it doesn't move any data from the original drive. So, using a clone should yield the same results as working from the original devices (assuming the clone is in fact an exact 1:1 copy) How do I check if the partial recovered/ recovered Pywallet is a valid wallet? If it said no key found do I still check it and how?? ( is there a simple easy way)??
Any wallet.dat file created by PyWallet should theoretically be a "valid" wallet file... it might be empty and contain no keys, but the file itself should still valid. If it said "no keys" found, then it probably won't have any keys... you can verify by using the PyWallet --dumpwallet command. |

There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, which will follow the rules of the network no matter what miners do. Even if every miner decided to create 1000 bitcoins per block, full nodes would stick to the rules and reject those blocks.

Any way some one can recover or regenerate (keys/ coins/ wallet) using a 12 word seed through an updated bitcoin core while offline?
or do u need a hardware wallet to do so?
in other words what's the best way to do an offline (keys/ coins/ wallet) recovery using a 12 word seed??
Thank you,

Thank you,
Import the seed into [offline] electrum and grab the wif + address. Alternatively you can download some page and open it offline https://iancoleman.io/bip39/ |

Not sure if u didn't get my question or if can't get your answer!!
My question was specifically about working offline on Bitcoin core ( that's where the original wallet was created and I have it already up to date).
Don't know much about Electrum but I though Electrum is an online only server!!
My understanding also is some/ not all hardware wallets can automatically regenerate private/ public keys ( basically restore your wallet) if you input into them the 12 words seed ( as a recovery).

Bitcoin Core does not, and never has, used 12 word seeds... if you have a 12 word seed, it was not created with Bitcoin Core. NOTE: There was a scam clone of Bitcoin Core that supposedly had a "12 word seed recovery phrase" that would be emailed to you when you downloaded/registered for the wallet. If you used this wallet, your coins are basically lost. |

WOW!! hmm, so how can I safely validate that seed I have?? any programs, software/ hardware I can use offline??? can I create a new wallet on bitcoin core using a seed where it scans through the block chain to match it?? |

What exactly are you attempting to "validate"?  Simply that it is a "valid" seed? Or that it generates a known AddressXYZ? As the previous poster mentioned... running Electrum offline and using the seed there (would probably need to use "Options -> BIP39 seed" on the seed entry screen) is an option. You could also download the "iancoleman" Mnemonic Code Converter and run that offline... it has instructions at the bottom of the page. can I create a new wallet on bitcoin core using a seed where it scans through the block chain to match it??
While it is possible to create a Bitcoin Core wallet from a seed... it is NOT possible to use a seed mnemonic... It's important to note the differences... a "Seed" is technically just a very, large, random number... while a seed mnemonic is the 12/24 words. Unfortunately, over the years... "seed" and "seed mnemonic" have been used somewhat interchangeably, which leads to confusion  There is a sethdseed command in Bitcoin Core: sethdseed ( newkeypool "seed" )
Set or generate a new HD wallet seed. Non-HD wallets will not be upgraded to being a HD wallet. Wallets that are already
HD will have a new HD seed set so that new keys added to the keypool will be derived from this new seed.
But you need to note that the "seed" used here is NOT a 12/24 word seed mnemonic... it is of the "very large random number" variety. If you have a "12 word" seed mnemonic... then your best chance of recovering anything is using a BIP39 compatible wallet like Electrum. Do you know/ remember who had a paper wallet/12 word seed back 10 years ago??
If it is 12 English words... and you're sure that its 10 years ago... then I have no idea... BIP39 was from 2013... Electrum was originally 2011... what is the exact timeframe you are working with? |

What exactly are you attempting to "validate"? Simply that it is a "valid" seed? Or that it generates a known AddressXYZ? Yes, I'm trying to validate that it's actually a valid seed for a valid wallet that still contains actual coins! As the previous poster mentioned... running Electrum offline and using the seed there (would probably need to use "Options -> BIP39 seed" on the seed entry screen) is an option. You could also download the "iancoleman" Mnemonic Code Converter and run that offline... it has instructions at the bottom of the page. can I create a new wallet on bitcoin core using a seed where it scans through the block chain to match it??

What I have is 12 words numbered 1 through 12 so I'm guessing it's a nemonic seed, so I'll try Electrum then. Do you know/ remember who had a paper wallet/12 word seed back 10 years ago??
If it is 12 English words... and you're sure that its 10 years ago... then I have no idea... BIP39 was from 2013... Electrum was originally 2011... what is the exact timeframe you are working with? some where between 2009 to 2011 it's all a fading memory! |

It could be an early Electrum wallet... but I think Electrum was announced late 2011... so it's not likely. Likewise, I think blockchain.info was late in 2011... and I think their early "X word phrases" (which were actually used for password recovery and NOT seed recovery) were like 15 words anyway. Seed Mnemonics were not that common back then... I mean BIP39 was only created in Sept 2013. Have you checked the words that you have against this list: https://github.com/bitcoin/bips/blob/master/bip-0039/english.txtI would also check this old Electrum list: https://github.com/spesmilo/electrum/blob/1.9.8/lib/mnemonic.pyIt's possible that your timeframe is off... so: - If ALL 12 words are in the BIP39 wordlist, try a BIP39 compatible wallet (you can also use Electrum for this... and select the "BIP39 Seed" option during seed entry) - If ALL 12 words are in the old electrum list, try using Electrum (it'll still work with old mnemonics) There may be other, more obscure wallets that were around in that time period... but I can't really think of any off the top of my head... |

It's possible that your timeframe is off... so: My time frame is sure between 09 and 2011, but the events are so faded!! - If ALL 12 words are in the BIP39 wordlist, try a BIP39 compatible wallet (you can also use Electrum for this... and select the "BIP39 Seed" option during seed entry) - If ALL 12 words are in the old electrum list, try using Electrum (it'll still work with old mnemonics) So if I download Electrum on a flash drive, then run it on my off line PC I will be able to plug the 12 word seed in, and see if it generates an address, then I can run this address through blockchain.com to see if it is valid, transactions history, and balances.... right?? There may be other, more obscure wallets that were around in that time period... but I can't really think of any off the top of my head... Would Electrum decrypt these seeds too? is it the same math and hashing...… to get keys from words? Thank you, |

The mnemonic code is not encrypted. The words are the mnemonic code, which is the seed encoded into a human-readable format. To answer your question.. no, it is not the same. BIP39 is different from electrums mechanism. And that's the reason HCP suggested that you check this: - If ALL 12 words are in the BIP39 wordlist, try a BIP39 compatible wallet (you can also use Electrum for this... and select the "BIP39 Seed" option during seed entry)
- If ALL 12 words are in the old electrum list, try using Electrum (it'll still work with old mnemonics)
Could you do this and report back ? |

I forgot to mention that if you have words that are not in either list, there is a chance that it's an old blockchain.info password recovery mnemonic... in which case, you would need the wallet backup file or "wallet-ID" and possibly access to the email address you used to sign up to that service. |

No... the password recovery system was simply that, it would allow you access back to your account... but is not capable of restoring the wallet "from nothing". You needed the "wallet.aes.json" backup file + password (which can be decrypted with a tool provided by blockchain.info) or Wallet-ID + password (+ access to email for 2FA), so you can log into their website The "old" recovery system is here: https://login.blockchain.com/wallet/forgot-password?guid=Their "new" recovery options are here: https://login.blockchain.com/#/help (the 12 word recovery option here is only valid for HD wallets from about 2016 onwards) Where people come unstuck with blockchain.info is that they don't understand they can't just do a password reset... your wallet is stored encrypted with your password. Not even blockchain can modify that, so if you forget your password, you're not able to recover. People have become so used to websites being able to reset passwords, they just don't believe that blockchain can't do the same... |

So the words aren't all on either list!! so if it's a blockchain password and I don't have a wallet ID can I scan my old PC to find this "wallet.aes.json" file? any special software or method to target such file?? do I have to enter the 12 words live online? or can I do it offline ( to a hardware wallet or software) to generate public/ private keys? any difference between blockchain.com/.info? |

That is problematic, as it means it is neither a BIP39 wallet seed mnemonic, nor an Electrum wallet seed mnemonic so if it's a blockchain password and I don't have a wallet ID can I scan my old PC to find this "wallet.aes.json" file? any special software or method to target such file??
Try the recovery methods at Blockchain.com... https://login.blockchain.com/#/helpIf you don't have wallet-id, but have an idea of what email address you might have used... and you still have access to the email address, you can try the wallet-id reminder option. You can also try the "Forgot your password" option and see if it works... unlikely given you have nonBIP39 words... so also try the old recovery: https://login.blockchain.com/wallet/forgot-password?guid=do I have to enter the 12 words live online? or can I do it offline ( to a hardware wallet or software) to generate public/ private keys?
Yes, it's an online web-based platform... so if you want to try blockchain.info recovery, you have to do it via their website. any difference between blockchain.com/.info? No, blockchain.info was moved to blockchain.com a while ago... the .info domain now redirects to .com |
