not your keys, not your coins!

Yes, it's a good solution with Electrum offline.
Slightly difficult for me though as my offline PC is the one with Windows 7, impossible to install the latest version of Electrum.
And I also am wondering about all options that exist.
As I am learning how everything works with wallets and private keys, and what is possible and what is impossible. And what solutions exist at all.

I don't know of any, sorry. But what you can definitely do is boot your PC or laptop using https://tails.boum.org/. You flash that to a USB drive and boot from it.
It comes with Electrum preinstalled and lets you import keys & sign a transaction without ever putting them on a 'hot' PC. Export the signed transaction to a second USB drive, reboot and broadcast the transaction.

For broadcasting, you would also need Electrum; if it doesn't run on your PC, you could spin up a VM.
Or download 4.1.5 as o_e_l_e_o said.

No, and it would be stupid for someone to even think about doing something like this.
Something similar could be done with importing seed words generated online in unsafe way, but I would never suggest stuff like this to any sane person.

I just want to move funds from software wallet (on PC which is always offline) without going online (if possible). So this option with importing several single private keys would be safer than the option with sending transaction.

No need to overcomplicate things so much...
Just move the damn coins from your old address to new one that is safely generated offline, and you are done.
That is if you want to be more secure, but you can do whatever you want if you like being unsecure.

Importing a private key in to a hardware wallet defeats the purpose of the hardware wallet in the first place, since it cannot guarantee that the private key was created securely and has remained permanently offline. For the same reason you should not import seed phrases created elsewhere in to a hardware wallet. The hardware wallet should be used as a standalone device to create its own wallets, and interact only with those wallets.

As I think I said to you in another thread, you should download and verify version 4.1.5 of Electrum from this link (https://download.electrum.org/4.1.5/), which works on Windows 7, to use on your offline computer. Use it to sign a transaction which sends all the coins from your offline wallet to a fresh address on your new hardware wallet.

I don't know if you'll find a HW that allows importing private key, I've never heard of such behavior for them (but you can give time, maybe others know).

I recommend you take a look onto Tails OS. It's an OS you can easily install onto an USB stick, it contains Electrum (and since you'll take care to always use it offline it should be OK, or you can download Electrum AppImage if you want to be extra sure). It's not a HW, it's a cold storage, you may need to give it some time to learn it, but it should be just fine for your needs.

Hi,

Does such a hardware wallet exist?
May be you know?
Brand/model doesn't matter, I just would like to know if such possibility exists at all.

Thank you!

I am not sure there is a hardware wallet you can import private keys to, but, for example, Coldcard allows users to restore wallets using extended master private keys (xprv). You can find more information on their documentation page: https://coldcard.com/docs/import From my point of view, the main reason most hardware wallets don't implement importing of single keys is that introduces additional problems to the security setup. Typically, your wallet's sensitive keys are generated by the hardware itself, and all information related to the signing of transactions is kept isolated from other parts of the system. When you "add" new private keys from external sources, you basically force your isolated keys to interact with this new key information, thereby ruining its isolation and making it vulnerable to attacks. That's not worth it to implement a feature of sweeping private keys on hardware because the main point of a hardware wallet is to protect the keys that are already inside.

Why don't you import the private keys on electrum, then send the coins to address(es) generated on an hardware wallet? That should be a good option to go for.

For safety. You can go for Electrum cold storage option before sending the coins to the addresses generated on the hardware wallet.
