Bitcoin-QT Private Key Question

I am attempting to obtain the private key from an address I have saved. I keep getting the same message "private key for address **** is not known (error -4)" Has anyone encountered this problem before?
Alternatively, I have a wallet.dat file that I believe contains the private key that I am looking for. However, I have not been able to figure out how to open it. The end goal is to move the wallet into Electrum, but I need the private key to do this.
Thanks for any help you could give me.

Are bitcoin-qt encrypted wallet private keys BIP38 enabled?

Does an encrypted bitcoin-qt wallet generates BIP38 private keys?
I saw that bitcoin private keys starting with 5, i.e. unencrypted / no-BIP38 PKs, can be imported on several bitcoin wallets, e.g. blockchain.info, electrum, etc., and everyone with access to these unencrypted PKs can spent the bitcoins associated to them without entering a password to validate the transaction. While BIP38's private keys, i.e. those starting with 6, can be imported on several bitcoin wallets, but they ask the associated password in order to move the coins associated with them.
So let's say that someone guess my bitcoin-qt's encrypted private key, and he import it on blockchain.info or electrum. Does he will need to enter my password to spent the coins associated to my PK? in other others, does my encrypted bitcoin-qt private keys works like any BIP38 PK?
Thanks

Which private key in bitcoin-qt wallet is needed to recreate total balance when importing to new wallet?

Hi,
I want to import the bitcoins of my bitcoin-qt wallet into another client.
I understand that this is done by importing a private key, that I can get with the "dumpprivkey" command on the public address.
However, there are multiple addresses in my wallet when I type "listaddressgroupings"
Which one of the addresses should I use to get the private key allowing to import the total bitcoin balance of the wallet into another client wallet?

Thanks

Bitcoin Core (Qt) wallet help, private keys, etc

Hello, I have encrypted my wallet on bitcoin core, made a backup of it. Is this good enough? Is is important to backup the private keys too? Or is the encrypted wallet sufficient? Or is the encrypted wallet only sufficient with bitcoin core while private keys are for using the wallet anywhere?
When backing up the private keys, do I backup the private key for every single receiving address I have? Because I make a new receiving address after each time I receive. And is this all I need just the receiving addresses and the private keys for each receiving addresses or do I need public address or other addresses too?
Thank you for any help!

Problems importing private key from paper wallet to bitcoin-qt

For testing purposes I sent some BTC to a paper wallet from my bitcoin-qt client and later, after ~50 confirmations I imported the private key from the paper wallet back into bitcoin-qt with the command importprivkey $key $label rescan and after half an hour of rescan it doesn't show anything. Well, almost nothing, it renamed the paperwallet address I sent to in the first place to "$label" in the outgoing transaction, but no other sign of the imported private key, especially the balance didn't change. The Blockchain explorer shows the funds are still under the associated paper wallet address. Anybody knows what's going on here, what I did wrong and how to do it correctly? Thanks!

What's the best way to export private keys from an old Bitcoin QT wallet

I have a backup of an old Bitcoin QT wallet (from 2013-ish). I know the wallet is empty, but I would still like to have a few of the private keys from it (to be able to prove that I was in possession of bitcoins at this time).
What is the best way to export a few private keys from the wallet? I'd rather not download the entire blockchain just to export a few keys.

Importing private keys into Bitcoin-qt

Hello all,
I’m looking for some advice for a problem I’m having. If this is the wrong sub for it please let me know and I'll be glad to post somewhere else. I need to access funds from a wallet that was generated on blockchain.info which uses seed words on a bitcoin-qt windows wallet. Since bitcoin-qt doesn’t support seed words it’s my understanding that I need to use a BIP39 generator to use my seed words to generate private keys. I’ve done this and was able to generate 30+ private keys which I managed to import into bitcoin-qt using the debug console. After the import I was able to see my tx’s up until the end of July 2017, but I cannot seem to find any transactions past July. These transactions im looking for include a balance of 1BTC which I simply cannot see from any of the private keys I imported. I could try to generate more than 30 private keys and see if any of them have tx’s but past the 25th key there are zero transactions so I’m doubtful that generating 40 or 50 will be anything more than a waste of time. I could be wrong though so I’m curious if anyone has any suggestions here? I need to import into the bitcoin client and using another wallet which supports seed words is not an option at this time. Thanks in advance. PS Is there any possibility the BIP39 generator is not showing me some of the keys? Isn't July 31 when a fork happened? Is it possible the generator isn't able to produce a newer format of key? (segwit?) . I'm using the BIP39 standalone generator from GitHub.

Invalid Private Key Encoding Error in Console (Bitcoin QT)

Not letting me input a private key in the console in QT. The key I am importing is encrypted.
Not sure if I am using an incorrect command line or have some brackets in the wrong place. Or if I need an additional command for the encryption phrase.
Any Help?

Transferring private keys from Bitcoin-qt to Electrum wallet, but amount is wrong?

So basically I started out with Bitcoin-qt years ago, but it's too cumbersome now with me needing the giant blockchain downloaded.
Anyway, I decided to try Electrum. I read how to extract my private keys from the bitcoin-qt wallet address, and import them into my newly created Electrum wallet.
Bitcoin-qt showed I had 9 receive addresses, and after importing all 9 into Electrum the amount isn't the same. While it's not a gigantic difference, Electrum shows roughly 0.015 BTC less than Bitcoin-qt. When I check all of the address on blockchain.info and add them all up it comes out to what Electrum is showing.
Does anybody know why Bitcoin-qt is showing more (which should be correct from all my previous transactions), and how to get the small remaining amount imported into Electrum without just transferring the balance (thus incurring a fee)?

Why isn't there a Wallet.dat or private key import feature in bitcoin-qt?

This is what I am asking myself for two years now and I finally decided to ask. In addition to that: why not a paper wallet print and import feature (maybe webcam support)?
I now that there is a ton of other potential features and the development takes time and so on. But these here appear to be extremely essential since using bitcoin is in fact very risky without these simple precautions.
You want unskilled users to search for a folder that is not even visible on a fresh system? The people who cant find this folder are the ones who also make other mistakes and the ones who get their bitcoins stolen.

Is it possible to encrypt user private keys in OpenBazaar installation the same way Bitcoin-QT encrypts bitcoin.dat, so that even if someone access filesystem there would be nothing to hack

When I created a topic about helping people with setting up VPS on /bitcoin, I got a lots of distrust, because people think that I'm going to steal their private keys.
No matter how much trusted your VPS provider are, they are also having access to file system where OpenBazaar-Server is running.
It seems like everybody already got OpenBazaar-Client software. What if the encryption scheme would work the same way like "Blockchain.info" wallet does, but even more reliable - because they are running their client Javascript over HTTP, but you got such a wonderful opportunity to give user to decrypt private keys on the side of OpenBazaar-Client. I mean here how it would work:
So is there any way to do this?
Also I still can't understand how multisignatures work? Where client stores his part of private key? Where moderator stores his part of private key? Where seller stores is part of private key?
My point is - how about creating such easy instruction for user, which says "If your computer with your OpenBazaar-Client is protected and got no viruses, then you've got nothing to worry about with your server side, no matter who hosting that thing for you"
What is the difference between storing private keys for direct Bitcoin address and storing private keys for multisig addresses in OpenBazaar?
