Crypto Authentication USB Dongle with ECDSA and more

Posted on by

So, you have something to hide? 🙂

The Irdroid’s Crypto authentication USB dongle is a device, that connect to your PC with Linux and allows you to digitally sign / verify / authenticate Documents using its built-in hardware crypto element, based on ATECC608B from Microchip.

What it can be used for?

  • SSH authentication with a remote system via ECDSA keypairs ( your private key never leaves the hardware secure element e.g the AuthKi)
  • ECDSA elliptic curve authentication with git / GitHub ( your private key never leaves the hardware secure element e.g the AuthKi)
  • Digital Signature and Verification of files via Ellliptic Curve Algorithms (ECDSA/ECDH)
  • Developing Secure Crypto Wallets for Bitcoin / Ethereum
  • Experimenting with the Microchip’s Cryptoauthlib for interfacing with the device.

For more information about the Project, please visit – https://irdroid.github.io/authKi/ or the project repository in GitHub

Irdroid- HTPC – Control your Kodi Media Center from your TV Remote

Posted on by
The Irdroid-HTPC Universal USB Infrared Remote Control Receiver for Kodi / HTPC media centers

The Irdroid-HTPC Universal USB Infrared Remote Control Receiver for Kodi / HTPC media centers

 

Recently I have installed the Kodi media center on an old thin client HP t620 computer. All was working very well except that I needed to use my TV remote with the the newly installed Kodi Media center and be able to control both the TV set and the media center from the same remote control.

I have tried using an HDMI CEC adapter, but with no success as HDMI CEC isnt’ properly supported in all manufacturers in my case I was experiencing significant issues with HDMI CEC remote control on Samsung with Anynet+ , so I have decided to check the possibilities with infrared remote control and decided to design one of my own – the Irdroid-HTPC USB Infrared Remote Control Receiver, that can be used to pair your existing TV remote , or any other TV Remote in order to control both your TV and Kodi media center at the same time.

The unit is equipped with long enought USB cable, directly attached to it and in my case it eased my installation. The unit has also Velcro dots with stiker-like pads which allow for easy fixing to any surface.

The Irdroid-HTPC enumerates via USB as a standard USB Keyboard, and pairing my TV Remote control with it was easy, by simply clicking the pair / program button and assigning my remote keys one after the other. I have also tested the Irdroid-HTPC on my Macbook PRO and on another laptop with MS Windows, both worked properly.

 

Below is a screenshot showing “dmesg” and device enumeration after insertion:

As you can see it does enumerate as a Standard HID device. The cool thing about this unit is that you don’t even need any software to pair your existing remote control with the receiver. It has a programming button on it which allows you to record the keys that you need from your remote control and map them automatically to specified keystrokes. They have the following keystrokes in firmware by default:

  • Up
  • Down
  • Left
  • Right
  • Enter
  • Back
  • Prev (*Shortcut to Favourites in Kodi)
  • Next (*Shortcut to Weather in Kodi)
  • Play/Pause

* The shortcuts can be assigned using the Kodi addon, designed for the Irdroid-HTPC

The unit stored my remote control buttons in its non-volatile eeprom memory and the procedure is carried just once, then it is ready for use. The infrared receiver is very sensitive ( with ir lens ) that provide great operation range and angle e.g you dont need to point the remote control toward the unit in order to be able to control your HTPC which is absolutely great!

In Kodi I have programmed the following keys from my remote control: up, down, left, right, enter, back, prev, next, play/pause. This was enought to take full control of kodi using my TV remote, and at the same time be able to control my tv with its remote control.

In addition to the above the Irdroid-HTPC is both open source software and open source hardware with their documentation and code published in GitHub. It will allow you to completely change the software / firmware of the unit by simply opening its Arduino Sketch in the Arduino IDE, changing the code as per your needs and reflashing it via USB (It is shipped with a version of the micronucleous bootloader, that is compatible with the Arduino IDE).

Another cool thing about this unit is that it is open hardware and the schematics and design files are available in Irdroid’s GitHub repository .

Supported Operating Systems

  • GNU Linux
  • Mac OS X
  • MS Windows
  • Android

Playing with Arduino Irdroid and Car Halo light led controller

Posted on by

The Car Halo LED Light controller is controlled using a cheap remote control using a EV1527 Encoder chip, which is compatible with the Arduino / Raspberry Pi  rc-switch library. I has able to clone the remote control buttons using a cheap RF radio transmitter and receiver AM modules, working at 433MHz. Then I was able to control the Car Halo Light led controller , using the Irdroid IoT SmartHub.

Manually parsing a Lircd.conf file in the Irdroid App.

Posted on by

In some cases, the automatic “update db” option will download automatically the default licd.conf file that ships with the Irdroid v.0.4 app, but it will not parse it in the UI. In this case you can use a “File Manager” application like this one to locate the downloaded database file. It should be downloaded and stored in your internal SD Card under the /sdcard/tmp/ folder. Locate the file named “t.conf” and copy it to your external SDcard under /tmp folder (create /tmp folder if it doesn’t exist) . Using the file manager tap on additional info when the t.conf file is selected and write down the full file path shown in the “additional info” (you will need it later in the Irdroid v.0.4 app) . Start the Irdroid app and select “Parse File” and enter the exact path to the “t.conf” file. Once done, the default remote brands will show up in the list of devices.
