Introduce GET BULK DATA to execute GET DATA in multiple DO with a single APDU.

It saves considerable bandwidth since only one APDU/RAPDU are transmitted.

+# Contributing
+
+Thank you for your interest in contributing to this project.
+
+This repository is published in two forms:
+- a Community Edition released under AGPLv3, and
+- a proprietary / commercial / Enterprise Edition offered to organizations.
+
+To keep that model legally clean, we need to be explicit about how contributions can be used.
+
+By opening a pull request, you agree to all of the following:
+
+1. **You have the right to contribute this code.**
+   You are either the original author of the contribution, or you have obtained the necessary rights/permissions to contribute it under these terms.
+
+2. **Dual licensing permission.**
+   You agree that your contribution may be:
+   - merged into this repository, and
+   - used, copied, modified, sublicensed, and redistributed
+     - under the AGPLv3 Community Edition, and
+     - under any proprietary / commercial / Enterprise editions of this project,
+       now or in the future.
+
+   In other words: you are granting the project maintainer(s) the right to include
+   your contribution in both the open-source (AGPLv3) codebase and in closed-source /
+   commercially licensed builds, without any additional approval or payment.
+
+3. **Attribution.**
+   The maintainers may keep or add attribution lines such as
+   `Copyright (c) <your name>` or an AUTHORS / CONTRIBUTORS list.
+   The maintainers may also make changes for clarity, style, security, refactoring,
+   or integration reasons.
+
+4. **No automatic SLA.**
+   Submitting a pull request does *not* create any support obligation,
+   service-level agreement, warranty, or guarantee that the contribution
+   will be reviewed, merged, or maintained.
+
+5. **Potential rejection for business reasons.**
+   Features that fall under "Enterprise / Commercial" functionality
+   (e.g. multi-tenant provisioning at scale, centralized audit trails,
+   corporate policy enforcement, attestation/branding flows, key escrow / dual-control,
+   etc.) may be declined for the public AGPLv3 tree even if technically valid.
+   That is normal: some functionality is intentionally offered only
+   under commercial terms.
+
+If you are not comfortable with these terms, **do not open a pull request yet.**
+Instead, please open an Issue to start a discussion.
+
+## How to contribute (technical side)
+
+### 1. 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.

+# Enterprise / Commercial Edition
+
+This project is offered under two editions:
+
+## 1. Community Edition (FOSS)
+
+The Community Edition is released under the GNU Affero General Public License v3 (AGPLv3).
+
+Intended for:
+- individual users and researchers
+- evaluation / prototyping
+- internal lab / security testing
+
+You are allowed to:
+- read and study the source code
+- modify it
+- run it internally
+
+Obligations under AGPLv3:
+- If you distribute modified firmware/binaries/libraries to third parties, you must provide the corresponding source code of your modifications.
+- If you run a modified version of this project as a network-accessible service (internal or external), you must offer the source code of those modifications to the users of that service.
+- No warranty, no support, no SLA.
+- Enterprise features (bulk provisioning, multi-user policy enforcement, device inventory / revocation, corporate PIN rules, custom attestation/identity, etc.) are NOT included.
+
+The Community Edition will continue to exist.
+
+## 2. Enterprise / Commercial Edition
+
+The Enterprise / Commercial Edition is a proprietary license for organizations that need to:
+
+- deploy this in production at scale (multiple devices / multiple users / multiple teams)
+- integrate it into their own physical product or appliance
+- run it as an internal service (VM / container / private cloud "HSM / auth backend") for multiple internal teams or tenants
+- enforce internal security policy (admin vs user roles, mandatory PIN rules, secure offboarding / revocation)
+- avoid any AGPLv3 disclosure obligations for their own modifications and integration code
+
+### What the Enterprise Edition provides
+
+**Base license package (always included):**
+- **Commercial license (proprietary).**
+  You may run and integrate the software/firmware in production — including virtualized / internal-cloud style deployments — without being required to disclose derivative source code under AGPLv3.
+- **Official signed builds.**
+  You receive signed builds from the original developer so you can prove integrity and provenance.
+- **Onboarding call (up to 1 hour).**
+  A live remote session to get you from "we have it" to "it’s actually running in our environment" with minimal guesswork.
+
+**Optional enterprise components (available on demand, scoped and priced per customer):**
+- **Production / multi-user readiness.**
+  Permission to operate the system with multiple users, multiple devices and multiple teams in real environments.
+- **Bulk / fleet provisioning.**
+  Automated enrollment for many tokens/devices/users at once (CSV / directory import), scripted onboarding of new users, initial PIN assignment / reset workflows, and role-based access (admin vs user).
+- **Policy & lifecycle tooling.**
+  Corporate PIN policy enforcement, per-user / per-team access control, device inventory / traceability, and secure revocation / retirement when someone leaves.
+- **Custom attestation / per-organization identity.**
+  Per-company certificate chains and attestation keys so devices can prove "this token/HSM is officially ours," including anti-cloning / unique device identity for OEM and fleet use.
+- **Virtualization / internal cloud deployment support.**
+  Guidance and components to run this as an internal service (VM, container, private-cloud HSM/auth backend) serving multiple internal teams or tenants under your brand.
+- **Post-quantum (PQC) key material handling.**
+  Integration/roadmap support for PQC algorithms (auth / signing) and secure PQC key storage inside the device or service.
+- **Hierarchical deterministic key derivation (HD).**
+  Wallet-style hierarchical key trees (BIP32-like concepts adapted to this platform) for issuing per-user / per-tenant / per-purpose subkeys without exporting the root secret — e.g. embedded wallet logic, tenant isolation, firmware signing trees, large fleets.
+- **Cryptographically signed audit trail / tamper-evident event logging.**
+  High-assurance logging of sensitive actions (key use, provisioning, PIN resets, revocations) with integrity protection for forensic / compliance needs.
+- **Dual-control / two-person approval ("four-eyes").**
+  Require multi-party authorization for high-risk actions such as firmware signing, key export, or critical configuration changes — standard in high-assurance / regulated environments.
+- **Secure key escrow / disaster recovery design.**
+  Split-secret or escrowed backup strategies so you don’t lose critical signing keys if a single admin disappears or hardware is lost.
+- **Release-signing / supply-chain hardening pipeline.**
+  Reference tooling and process so every production firmware/binary is signed with hardware-backed keys, proving origin and preventing tampering in transit or at manufacturing.
+- **Policy-locked hardened mode ("FIPS-style profile").**
+  Restricted algorithms, debug disabled, no raw key export, tamper-evident configuration for regulated / high-assurance deployments.
+- **Priority support / security response SLA.**
+  A direct line and guaranteed response window for production-impacting security issues.
+- **White-label demo / pre-sales bundle.**
+  Branded demo firmware + safe onboarding script so you can show "your product" to your own customers without exposing real production secrets.
+
+These components are NOT automatically bundled. They are available case-by-case depending on your use case and are priced separately.
+
+### Licensing models
+
+- **Internal Use License**
+  Internal production use within one legal entity (your company), including internal private cloud / virtualized deployments for multiple internal teams.
+  Optional enterprise components can be added as needed.
+
+- **OEM / Redistribution / Service License**
+  Integration into a product/appliance you ship to customers, OR operating this as a managed service / hosted feature for external clients or third parties.
+  Optional enterprise components (attestation branding, PQC support, HD key derivation, multi-tenant service hardening, audit trail, etc.) can be added as required.
+
+Pricing depends on scope, fleet size, number of users/tenants, regulatory requirements, and which optional components you select.
+
+### Request a quote
+
+Email: pol@henarejos.me
+Subject: `ENTERPRISE LICENSE <your company name>`
+
+Please include:
+- Company name and country
+- Intended use:
+  - Internal private deployment
+  - OEM / external service to third parties
+- Approximate scale (number of devices/tokens, number of users/tenants)
+- Which optional components you are interested in (bulk provisioning, policy & lifecycle tooling, attestation branding / anti-cloning, virtualization/cloud, PQC, HD key derivation, audit trail, dual-control, key escrow, supply-chain signing, hardened mode, SLA, white-label demo)
+
+You will receive:
+1. A short commercial license agreement naming your company.
+2. Access to the base package (and any optional components agreed).
+3. Scheduling of the onboarding call.
+
+## Why Enterprise exists
+
+- Companies often need hardware-backed security (HSM, FIDO2, OpenPGP, etc.) under their own control, but cannot or will not open-source their internal security workflows.
+- They also need multi-user / fleet-management features that hobby users do not.
+- The commercial license funds continued development, maintenance and new hardware support.
+
+The Community Edition remains AGPLv3.
+The Enterprise Edition is for production, scale, and legal clarity.

-freedoms that you received.  You must make sure that they, too, receive
-or can get the source code.  And you must show them these terms so they

+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they

+ensure that, in such cases, the modified source code becomes available

+a publicly accessible server, gives the public access to the source
+code of the modified version.
 
-  For the developers' and authors' protection, the GPL clearly explains
-that there is no warranty for this free software.  For both users' and

 OpenPGP cards are used to manage PGP keys and do cryptographic operations, such as keypair generation, signing and asymmetric deciphering. Pico OpenPGP follows the [**OpenPGP 3.4.1** specifications](https://gnupg.org/ftp/specs/OpenPGP-smart-card-application-3.4.pdf "**OpenPGP 3.4.1** specifications"), available at [GnuPG](http://gnupg.org "GnuPG").

-All secret keys (asymmetric and symmetric) are stored encrypted in the flash memory of the Raspberry Pico. DEK is used as a 256 bit AES key to protect private and secret keys. Keys are never stored in RAM except for signature and decryption operations and only during the process. All keys (including DEK) are loaded and cleared every time to avoid potential security flaws.

DEK is a 256 bit AES key used to protect private and secret keys. Keys are never stored in RAM except for signature and decryption operations and only during the process. All keys (including DEK) are loaded and cleared every time to avoid potential security flaws.
 
-At the same time, DEK is encrypted with doubled salted and hashed PIN. Also, the PIN is hashed in memory during the session. Hence, PIN is never stored in plain text neither in flash nor in memory. Note that PIN is conveyed from the host to the Pico in plain text if no secure channel is provided.
+At the same time, DEK is encrypted with doubled salted and hashed PIN. For RP2350 and ESP32-S3 microcontrollers it is masked by a secure device 32 bytes key. Also, the PIN is hashed in memory during the session. Hence, PIN is never stored in plain text neither in flash nor in memory. Note that PIN is conveyed from the host to the Pico in plain text if no secure channel is provided.
 
 If the Pico is stolen the contents of private and secret keys cannot be read without the PIN, even if the flash memory is dumped.
 
+### RP2350 and ESP32-S3
+RP2350 and ESP32-S3 microcontrollers are equipped with advanced security features, including Secure Boot and Secure Lock, ensuring that firmware integrity and authenticity are tightly controlled. Both devices support the storage of the Device Encryption Key (DEK) in an OTP (One-Time Programmable) memory region, making it permanently inaccessible for external access or tampering. This secure, non-volatile region guarantees that critical security keys are embedded into the hardware, preventing unauthorized access and supporting robust defenses against code injection or firmware modification. Together, Secure Boot and Secure Lock enforce firmware authentication, while the DEK in OTP memory solidifies the foundation for secure operations.

 ## Download
-Please, go to the [Release page](https://github.com/polhenarejos/pico-openpgp/releases "Release page"))  and 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 OpenPGP.**
 
-Note that UF2 files are shiped with a dummy VID/PID to avoid license issues (FEFF:FCFD). If you are planning to use it with OpenSC or similar, you should modify Info.plist of CCID driver to add these VID/PID or use the VID/PID patcher as follows: `./patch_vidpid.sh VID:PID input_openpgp_file.uf2 output_openpgp_file.uf2`
+If you own a Raspberry Pico (RP2040 or RP2350), go to [Download page](https://www.picokeys.com/getting-started/), select your vendor and model and download the proper firmware; or go to [Release page](https://www.github.com/polhenarejos/pico-openpgp/releases/) and download the UF2 file for your board.
 
-You can use whatever VID/PID (i.e., 234b:0000 from FISJ), but remember that you are not authorized to distribute the binary with a VID/PID that you do not own.

+
+Note that the [PicoKey App](https://www.picokeys.com/picokeyapp/ "PicoKey App") is the most recommended.
+
+## Build for Raspberry Pico
 Before building, ensure you have installed the toolchain for the Pico and the Pico SDK is properly located in your drive.
+```
+git clone https://github.com/polhenarejos/pico-openpgp
+git submodule update --init --recursive
+cd pico-openpgp
+mkdir build
+cd build
+PICO_SDK_PATH=/path/to/pico-sdk cmake .. -DPICO_BOARD=board_type -DUSB_VID=0x1234 -DUSB_PID=0x5678
+make
+```
+Note that `PICO_BOARD`, `USB_VID` and `USB_PID` are optional. If not provided, `pico` board and VID/PID `FEFF:FCFD` will be used.
 
-    git clone https://github.com/polhenarejos/pico-openpgp

-    PICO_SDK_PATH=/path/to/pico-sdk cmake .. -DPICO_BOARD=board_type -DUSB_VID=0x1234 -DUSB_PID=0x5678
-    make
+Additionally, you can pass the `VIDPID=value` parameter to build the firmware with a known VID/PID. The supported values are:
 
-Note that PICO_BOARD, USB_VID and USB_PID are optional. If not provided, pico board and VID/PID FEFF:FCFD will be used.

+- `NitroStart`
+- `NitroPro`
+- `Nitro3`
+- `Yubikey5`
+- `YubikeyNeo`
+- `YubiHSM`
+- `Gnuk`
+- `GnuPG`
 
-After make ends, the binary file pico_openpgp.uf2 will be generated. Put your pico board into loading mode, by pushing BOOTSEL button while pluging on, and copy the UF2 to the new fresh usb mass storage Pico device. Once copied, the pico mass storage will be disconnected automatically and the pico board will reset with the new firmware. A blinking led will indicate the device is ready to work.
+After running `make`, the binary file `pico_openpgp.uf2` will be generated. To load this onto your Pico board:
+

+2. Copy the `pico_openpgp.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.
