[NOW AVAILABLE] BTChip / Ledger HW1 : Bitcoin Hardware Wallet in a USB smartcard

[owlcatz]

There is an option for using security keys when trying to log in to Google.

https://support.google.com/accounts/answer/6103523?hl=en

Is it possible to use the HW.1 key to secure my Google account while also using it to secure my Bitcoin wallet?

no, it's unfortunately not possible. The U2F implementation is done on a different firmware version requiring attestation keys that are installed at factory personalization time

Seems like a good project, keep it up and I hope these smart cards can get made!

well the cards are made and actually quite popular at TNABC

I got one yesterday in the mail. can't get any computer to even recognize it. how do i tell if it's dead or something? spent like 2 hours with it, waste of time so far...

Edit - two windows 7 64-bit - even tried old drivers etc. nothing seems to work ... Windows device manager sees nothing at all, no matter what usb port i try. 1 Dell laptop and 1 ASUS home built desktop.

ps i tried on linux mint as well, but i didn't get very far at all before giving up there too.  (Older laptop).

thanks for any help.

the card is supposed to appear as a usb device on 2581:2b7c on your system (using windows control panel / lsusb on Linux)

if it doesn't, check that you folded it properly

if it still doesn't work, contact support to get another one sent

ok, thanks. i guess mine must be dead - I accidentally broke it off on the "clip" before reading the full instructions, but it's stuck back on there just fine so i'm not sure if that is the issue, i wouldn't think so, it fits fairly snug etc.

i'll have a super-geek i work with give a try tomorrow before contacting support, maybe i'm missing something simple.

Thanks again, i appreciate the quick response.

In Windows Device Manager it will show up as an HID (Human Interface Device). The computer sees it as a keyboard. It will not show up under the USB tab.

yes, might just be slightly off - try to nudge it a bit up in the USB port maybe.

Are these things still being shipped? I put an order through on hardwarewallet.com and it never accepted my payment =( ... I sent the BTC and it confirmed and I confirmed the addresses were the same. I never received an email or anything. I emailed hardwarewallet bout it ...
Anyone got ideas?

How long ago did you buy? When I bought mine there is no confirmation or contact after paying. They just mail it out and you receive it by regular airmail or registered airmail depending on the country you live in.

If everything goes through correctly, the payment page transforms in to a PDF confirmation receipt.

One of my orders failed to progress normally, so I emailed support and they sorted it out.

You could potentially also login to you payment history if the wallet you paid through supports BitID (probably only mycelium on android)

It would be awesome if there was a piece of software that anyone could use to turn a normal USB drive into a hardware wallet. But until then, this will do very nice to secure me

Can I use greenbits on android to do all that is needed in wallet mode with the hw-1? I mean from initialization through usage? Or do I need to use a computer for some steps?

Also, does hw-1 use it's own rng? Or does it use that of the host? Or some combination? Is it possible to add your own salt?

Also is the 2fa via usb keyboard emulation required for every transaction or is that optional?

Is hw-1 basically the same as ledger with a different form factor? Or are there usability differences?

(sorry if these are answered elsewhere in this thread... I read back several pages and didn't see anything conclusive).

You'll need to use a computer for initialization.

Also, does hw-1 use it's own rng? Or does it use that of the host? Or some combination? Is it possible to add your own salt?

It uses its own RNG, or a seed provided by the user. After that, the RNG is not used if using deterministic signatures. It's not possible to add your own salt.

Also is the 2fa via usb keyboard emulation required for every transaction or is that optional?

It is required for every transaction - with the latest Ledger Wallet firmware, you can replace it by a security card lookup or a mobile second factor though.

It's the same chip in a different form factor - with the latest firmware, both are exactly similar features wise.

Thanks very much for the reply. One more question: is it possible to export xpub from the device so you can generate receiving addresses without having the device plugged in? What I mean is using it with mycelium or BTCRecieve for watch only but also for generating receiving addresses.

yes, it's possible. It's not widely used so far, but you can find some examples in https://github.com/BitMEX/btchip-signing-tools for example.

Integration into Mycelium is also ongoing

[WBF1]

Sounds great. Being able to easily load up xpub into mycelium, the ledger companion app, or btcrecieve (which the trezor folks have rebranded into the "my trezor lite" app) would make it much easier to receive funds to new addresses in the hd wallet without needing the device connected. Definitely something I would think most users would be interested in, especially if btchip-based devices are being used for cold storage and kept in a safe, not readily accessible place.

Error. Obviously because of the slow internet.

Code:

Processing dependencies for btchip-signer==0.1
Searching for python-dateutil
Reading https://pypi.python.org/simple/python-dateutil/
error: The read operation timed out

Can anybody list the dependencies so that I can install them one by one? If the dependencies are pre-installed, it will be skipped when running the setup right?

P.S. What can we do with signTxArmory?

[WBF1]

Does hw1/ledger/greenaddress work on chromium instead of chrome? Wasn't sure if this is a btchip question or a greenaddress question...

If nobody is at it before I do, I'll have a look in the coming weeks. The Python implementation has some annoying low level bugs (related to the HID support) that need to be addressed.

P.S. What can we do with signTxArmory?

Initially perform multi signature with Armory lockboxes, but we run into an issue regarding compressed keys support in P2SH scripts when this was done (circa October 2014) which prevented us from moving forward. I don't know what's the status nowadays.

yes, everything should work fine on Chromium. The USB connectivity extensions are present in both versions.

@btchip I got an hw1 in the mail. Tried everything and can't get it to work. You prefer troubleshooting here or by email or irc? (or are you even the right person to contact?)

yes, email would be preferred (support@ledgerwallet.com)

Hi! I maybe able to help you. Can you give more details please?

• Which wallet are you trying to use with HW. 1?
• Which OS?

I suggest you to use Electrum 2.0 or Multibit beta wallet or GreenAddress. You may also use BTChip API.
