Thanks, Tommy. I just walked away from a lame experience with Scanova. The payment process the Biz Dev Dir. Yours is the second article citing QRStuff. Giving it a deeper look.

Could I enter my own private key on the sd? This is why you should always use a passphrase. The passphrase is not stored on the sd card and act as an extra word in the conversion from the word seed list to private keys. Seems this could drastically increase security. The protection would be limited. I'm trying to minimize the changes with the original trezor code to avoid to introduce all kinds of possible errors security, malfunction..
Also, all the code is open source, so anybody could review it and see how encryption is used. The passphrase could in theory be used to protect the partition that hold the flash image, but, when the online wallet is asking for it when the trezor is connected, the flash image is already loaded by the pitrezor to tell wallet to ask for the password.
This is a chicken'n'egg problem. I could solve it by breaking the flash in 2 parts one encrypted, one not but that will be a big change from the original code. The pin is not a real protection because it can be extracted from a dump of the flash image. The best protection is the passphrase because it is never stored.
For the 'ultra paranoid' security conscious people, couldn't you just add passphrase protection, then remove the SD card from your Pi-Trezor, put it in your "Etcher" application and create a new image, then encrypt the image with say TrueCrypt yes I know about it's apparent flaws and store it on a second USB drive somewhere offline, and extract the encrypted image only when needed? This is untested by myself, just theory in my head. Hello there! Thank you for this amazing work. Looking at build-pitrezor.
How safe it is? The daemon rng-tool is running as a separate process. The kernel will mix that source of entropy with others sources. Hi there. Yannick, you made a great job! I followed your instructions and made this device. Hope this helps someone. I will try it. Did you had to add the proper boot files in the boot partition because my image contains only the file for the pizero? Thanks for sharing. Good luck. Just finished the assembly, works great, thanx Yannick! Protected all the solder joints and reinforced the usb connector with the steel epoxy.
The case is 3d printed, just slightly larger than the pi zero itself. I like how slim you made the unit! I'll have to do some thorough redesign of my quick hack case to look as good as yours :. The hdmi connector is needed only if you dont have an oled.
But because you seems to have one, it can be used to help troubleshoot if the oled is not working, i. Hello, i will be also writing this via e-mail. I was wondering if it would be possible to use this with a 16x2 LCD display?
Thank you so much. Great Work! Is there a way to way to run this and an alternative OS? A dual boot option selectable on the screen perhaps? Is the model T code able to be emulated in this way? Just questions, thank you for your hard work! The current OS is based on yocto but yes in theory another OS like raspbian should work.
However, it would require to apply the same patch kernel linux patch to work properly. For the model T, I didn't invest time into it as it would require a color touch screen LCD and that would increase the cost of this project.
I meant like a dual boot situation. Hold one button to boot into the wallet, hold nothing for say, raspbian to load. More stealthy I see about the model T as far as touchscreen goes.
Thank you, once again, for your hard work. It is awesome. Hi Yannick! First of all awesome work thanks for your effort! Hi Yannik. Thanks for your great work. Any plans for an update of the firmware?
Could you explain to me how to solder the buttons. What pins should I be soldering? You must use buttons that make contact when you press them current flowing when pressed. You can try with a tester on that back of the pcb to check if current is flowing when pressed. Could be a bad solder. Is it possible to encrypt the sd card in a way that it will work? I looked it up and a lot of answers says its in general very difficult to encrypt a sd card or not worth bc of the power and so on.
How can i secure the hardware wallet more? Thank you very much! Encryption would require to change the original firmware and wallet software to let the user input the key to unlock part of the SD that contain the firmware at least the seed. This change would made the pitrezor not compatible with the current trezor ecosystem.
The best thing right now is to use a passphrase when you open the trezor wallet. This is fully supported by the trezor wallet and the passphrase is not stored on the SD card so it provides a good protection. Hello, thank you very much for such a good tutorial, I have applied it and I just have my wallet working perfect. Now Trezor has just released a firmware update, how should I apply the update, can I do it directly from the Trezor page, how to follow the steps for the commercial device, or should I do it by loading the new firmware to SD memory?
I have that little question. I appreciate the information. Thank for the good feedback. No, you cannot use the official firmware from trezor because it is not compatible with the pi. I will provide a new firmware update on this site in the next few days Hello Yann sorry can you help me about my issue my pitrezor is not recognized.
Thank you very much for your work. There is a new firmware update for trezor. Are you planning to update the piTrezor? Thank you very much. Thanks Yannick!! Thank you very much or the video. I had the idea of doing something similar but I don't have the talent for that. I put the link to your video in the page just beside the instructions. However I'm not sure if it's compatible do you have any knowledge of this working?
Yannick, this is a really great work! I have two small questions, you mention that it can be created a wallet passphrase to add more security, where do you create it? And second one, with this image you can create either a Trezor One or Trezor T wallet? Thanks in advance. Thank you. For the image it support only the Trezor One. If I've already a wallet created and I want now to add a passphrase, is it possible? I have to make a new wallet with the passphrase and send the crypto from one to the other?
Sorry my noob question :. Unfortunately, you will have to make a transaction and pay the transaction fee to move the fund from the original account to an address controlled by the password protected account. Hello, ask. Has anyone used pioled tft 1. I intend to buy this model. Coukd you solve this? Thank you for the comments and don't forget small donations are always welcome.
I usually post update a few days after they are released officially by trezor. Would you share the config you use for the waveshare display and in which mode you configured it?
