Flipper Seos

Flipper app for reading and emulating Seos-compatible cards/fobs/mobile credentials.

Demo Video

Note

This software incorporates a third-party implementation of Seos™ technology. It is not developed, authorized, licensed, or endorsed by HID Global, ASSA ABLOY, or any of their affiliates. References to Seos™ are solely for descriptive and compatibility purposes.

No guarantee of compatibility or functionality is made. This implementation may not work with all Seos™-enabled systems, and its performance, security, and reliability are not assured. Users assume all risks associated with its use.

Seos™, HID Global, and ASSA ABLOY are trademarks or registered trademarks of their respective owners. This software is not associated with or sponsored by them in any way.

To do:

  • Fix iso14443a-4 framing
  • ASN.1 for serializing/deserializing
  • Support for larger message wrapping/unwrapping
  • When parsing incoming data, use buffer + len instead of BitBuffer so I can increment buffer pointer as I parse header(s)
  • CMAC checking where I missed it

Keys

The app uses all 00 keys by default. If you'd like to use your own keys, use the format of the keys-example.txt to specify them, and place into SD Card/apps_data/seos/keys.txt

Hardware for BLE support (experimental)

  1. Install/setup nordic SDK
  2. Install Toolchain manager
  3. Launch Toolchain manager
  4. Next to SDK version click down arroy and "open terminal"
  5. navigate to samples/bluetooth/hci_uart_3wire

nRF52840

  1. Edit boards/nrf52840dk_nrf52840.overlay and change current-speed to 460800 to match Flipper app.

  2. west build -b nrf52840dk_nrf52840 -p auto

  3. west flash

nRF52840 dongle

  1. Copy boards/nrf52840dongle_nrf52840.overlay to hci_uart_3wire
  2. Might need to: nrfutil install nrf5sdk-tools
  3. west build -b nrf52840dongle_nrf52840 -p auto
  4. nrfutil nrf5sdk-tools pkg generate --hw-version 52 --sd-req=0x00 --application ./build/hci_uart_3wire/zephyr/zephyr.hex --application-version 1 app.zip
  5. Put dongle into DFU by pressing 'reset' button
  6. nrfutil nrf5sdk-tools dfu usb-serial -pkg app.zip -p /dev/cu.usbmodemD39BF26162261
