All features comply with the specifications. If you encounter unexpected behavior or deviations from the specifications, please open an issue. ## Security Considerations +Microcontrollers RP2350 and ESP32-S3 are designed to support secure environments when Secure Boot is enabled, and optionally, Secure Lock. These features allow a master key encryption key (MKEK) to be stored in a one-time programmable (OTP) memory region, which is inaccessible from outside secure code. This master key is then used to encrypt all private and secret keys on the device, protecting sensitive data from potential flash memory dumps. -Pico FIDO is an open platform, so exercise caution. The flash memory contents can be easily dumped, potentially revealing private/master keys. It is not feasible to encrypt the content, meaning at least one key (the master key) must be stored in clear text. - -If the Pico is stolen, the private and secret keys can be accessed. +**However**, the RP2040 microcontroller lacks this level of security hardware, meaning that it cannot provide the same protection. Data stored on its flash memory, including private or master keys, can be easily accessed or dumped, as encryption of the master key itself is not feasible. Consequently, if an RP2040 device is stolen, any stored private or secret keys may be exposed. ## Download -Please visit the [Release page](https://github.com/polhenarejos/pico-fido/releases "Release page") to download the UF2 file for your board. +**If you own an ESP32-S3 board, go to [ESP32 Flasher](https://www.picokeys.com/esp32-flasher/) for flashing your Pico FIDO.** -Note that UF2 files are shipped with a dummy VID/PID to avoid license issues (FEFF:FCFD).

Put the Pico board into loading mode by holding the `BOOTSEL` button while plugging it in. +2. Copy the `pico_fido.uf2` file to the new USB mass storage device that appears. +3. Once the file is copied, the Pico mass storage device will automatically disconnect, and the Pico board will reset with the new firmware. +4. A blinking LED will indicate that the device is ready to work. ## Led blink Pico FIDO uses the led to indicate the current status.

PIN is also an input vector, which defines a separated domain. PIN is used to derive encryption key, derive session key and derive verifier. From session key is derived encryption key. As a consequence, MKEK functionalities are not necessary anymore, since key device is handled by this new set directly. Some MKEK functions are left for compatibility purposes and for the silent migration to new format. It also applies for double_hash_pin and hash_multi, which are deprecated.

Main changes: - Replace GPLv3 headers with AGPLv3 headers in source files. - Update LICENSE file to the full AGPLv3 text. - Add ENTERPRISE.md describing the dual-licensing model: * Community Edition: AGPLv3 (strong copyleft, including network use). * Enterprise / Commercial Edition: proprietary license for production / multi-user / OEM use without the obligation to disclose derivative code. - Update README with a new "License and Commercial Use" section pointing to ENTERPRISE.md and clarifying how companies can obtain a commercial license. Why this change: - AGPLv3 ensures that modified versions offered as a service or deployed in production environments must provide corresponding source code. - The Enterprise / Commercial edition provides organizations with an alternative proprietary license that allows internal, large-scale, or OEM use (bulk provisioning, policy enforcement, inventory / revocation, custom attestation, signed builds) without AGPL disclosure obligations. This commit formally marks the first release that is dual-licensed: AGPLv3 for the Community Edition and a proprietary commercial license for Enterprise customers.

Bug reports / issues +- Please include: + - hardware / board revision + - firmware / commit hash + - exact steps to reproduce + - expected vs actual behavior + - logs / traces if available (strip secrets) + +Security-sensitive findings: do **not** post publicly. +Send a short report by email instead so it can be triaged responsibly. + +### 2. Small fixes / minor improvements +- You can open a PR directly for: + - bug fixes + - portability fixes / new board definitions + - clarifications in code comments + - build / tooling cleanup + - documentation of existing behavior + +Please keep PRs focused (one logical change per PR if possible). + +### 3. Larger features / behavior changes +- Please open an Issue first and describe: + - what problem you're solving (not just "add feature X") + - impact on existing flows / security model + - any new dependencies + +This helps avoid doing a bunch of work on something that won't be accepted +in the Community Edition. + +### 4. Coding style / security posture +- Aim for clarity and small, auditable changes. This code runs in places + where secrets live. +- No debug backdoors, no "just for testing" shortcuts left enabled. +- Keep external dependencies minimal and license-compatible + (MIT / Apache 2.0 / similarly permissive is usually fine). + +### 5. Commit / PR format +- Use descriptive commit messages ("Fix PIN retry counter wrap" is better than "fix stuff"). +- In the PR description, please include a short summary of what was changed and why. +- At the bottom of the PR description, **copy/paste and confirm the licensing line below**: + + > I confirm that I have read `CONTRIBUTING.md` and I agree that this contribution may be used under both the AGPLv3 Community Edition and any proprietary / commercial / Enterprise editions of this project, now or in the future. + +A PR without that confirmation may be delayed or closed without merge. + +## Thank you + +This project exists because people build on it, break it, fix it, +and push it into places it wasn't originally designed to go. + +Whether you are here for research, hacking on hardware, +rolling out secure keys for a team, or building a commercial product: +thank you for helping improve it. -- 2.34.1 From cf0686f857b8f6d78cbebc3c604df6814b463dc0 Mon Sep 17 00:00:00 2001 From: Pol Henarejos Date: Mon, 27 Oct 2025 08:57:59 +0100 Subject: [PATCH 222/290] Add template for pull requests.
