-# Changelog
-All notable changes to this project will be documented in this file.
-
-The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
-and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
-
-## [Unreleased]
-
-## [1.1.0] - 2019-02-17
-### Added
-- Code cleanup
-- Buffer over-read bug fix
-- U2F counter endianness bug fix
-- More testing
-- Extension interface to U2F and FIDO2
-    - Read firmware version
-    - Read RNG bytes
-
-## [1.1.1] - 2019-03-01
-
-- This version fixes an incorrect error code returned in U2F.  
-
-## [2.0.0] - 2019-03-01
-
-- Merge of NFC functionality branch
-- Bug fix with compiled USB name being too long causing buffer overrun
-- Change upper byte of counter from `0xff` to `0x7f` to fix issues with some websites.
-
-## [2.1.0] - 2019-03-31
-
-WARNING: This update may break previous registrations! This is because we fixed the U2F counter for good (rather than arbitrarily set the upper byte high for backwards-compatibility reasons, which ends up causing other issues).
-
-- Adds hmac-secret extension support. This extension is used for generating 32 or 64 byte symmetric keys using parameters from the platform and secrets on the authenticator. It's used by Windows Hello - - for offline authentication.
-- Fix bug in FIDO auth, where setting the pin requires all previous registrations to use pin. Only UV bit needs to be cleared.
-- Slightly change serial emulation USB descriptor to make it less abused by Linux Modem Manager.
-
-## [2.2.0] - 2019-04-17
-
-- Fixes the ordering of keys encoded in CBOR maps to be canonical ordering. They previously were not ordered in any particular way and caused issues for Chrome. #170
-- Fixes CTAP2 implementation to accept credential IDs created by the CTAP1 implementation. So registering with U2F and later authenticating with FIDO2 should work.

 Solo is an upgrade to [U2F Zero](https://github.com/conorpp/u2f-zero). It was born from Conor's passion for making secure hardware, and from our shared belief that security should be open to be trustworthy, in hardware like in software.
 
-Contributors are welcome. The ultimate goal is to have a FIDO2 security key supporting USB, NFC, and BLE interfaces, that can run on a variety of MCUs.

+# Booting into bootloader mode
+
+You can put Solo into bootloader mode by holding down the button, and plugging in Solo.  After 2 seconds, bootloader mode will activate.
+You'll see a yellowish flashing light and you can let go of the button.
+
+Now Solo is ready to [accept firmware updates](/solo/signed-updates).  If the Solo is a secured model, it can only accept signed updates, typically in the `firmware-*.json` format.
+
+If Solo is running a hacker build, it can be put into bootloader mode on command.  This makes it easier for development.
+
+```bash
+solo program aux enter-bootloader
+```
+
+# The boot stages of Solo
+
+Solo has 3 boot stages.
+
+## DFU
+
+The first stage is the DFU (Device Firmware Update) which is in a ROM on Solo.  It is baked into the chip and is not implemented by us.
+This is what allows the entire firmware of Solo to be programmed.  **It's not recommended to develop for Solo using the DFU because 
+if you program broken firmware, you could brick your device**.
+
+On hacker devices, you can boot into the DFU by holding down the button for 5 seconds, when Solo is already in bootloader mode.
+
+You can also run this command when Solo is in bootloader mode to put it in DFU mode.
+
+```bash
+solo program aux enter-dfu
+```
+
+Note it will stay in DFU mode until to tell it to boot again.  You can boot it again by running the following.
+
+```bash
+solo program aux leave-dfu
+```
+
+*Warning*: If you change the firmware to something broken, and you tell the DFU to boot it, you could brick your device.
+
+## Solo Bootloader
+
+The next boot stage is the "Solo bootloader".  So when we say to put your Solo into bootloader mode, it is this stage.
+This bootloader is written by us and allows signed firmware updates to be written.  On Solo Hackers, there is no signature checking
+and will allow any firmware updates.
+
+It is safe to develop for Solo using our Solo bootloader.  If broken firmware is uploaded to the device, then the Solo
+bootloader can always be booted again by holding down the button when plugging in.
+
+## Solo application
+
+This is what contains all the important functionality of Solo.  FIDO2, U2F, etc.  This is what Solo will boot to by default.

-## Pre-programmed Solo Hacker
-
-If your Solo device is already programmed (it flashes green when powered), we recommend
-programming it using the Solo bootloader.
-
-```
-solo program aux enter-bootloader
-solo program bootloader solo.hex
-```
-
-Make sure to program `solo.hex` and not `all.hex`.  Nothing bad would happen, but you'd
-see errors.
-
-If something bad happens, you can always boot the Solo bootloader by doing the following.
-
-1. Unplug device.
-2. Hold down button.
-3. Plug in device while holding down button.
-4. Wait about 2 seconds for flashing yellow light.  Release button.
-
-If you hold the button for an additional 5 seconds, it will boot to the ST DFU (device firmware update).

-# powercycle key
-solo program dfu all.hex
-```
-
-Make sure to program `all.hex`, as this contains both the bootloader and the Solo application.
-
-If all goes well, you should see a slow-flashing green light.
-
-##  Solo Hacker vs Solo
-
-A Solo hacker device doesn't need to be in bootloader mode to be programmed, it will automatically switch.
-
-Solo (locked) needs the button to be held down when plugged in to boot to the bootloader.
-
-A locked Solo will only accept signed updates.
-
-## Signed updates
-
-If this is not a device with a hacker build, you can only program signed updates.
-
-```
-solo program bootloader /path/to/firmware.json
-```
-
-If you've provisioned the Solo bootloader with your own secp256r1 public key, you can sign your
-firmware by running the following command.
-
-```
-solo sign /path/to/signing-key.pem /path/to/solo.hex /output-path/to/firmware.json
-```
-
-If your Solo isn't locked, you can always reprogram it using a debugger connected directly
-to the token.
-
-# Permanently locking the device
-
-If you plan to be using your Solo for real, you should lock it permanently.  This prevents
-someone from connecting a debugger to your token and stealing credentials.
-
-To do this, build the locked release firmware.
-```
-make build-release-locked
-```
-
-Now when you program `all.hex`, the device will lock itself when it first boots.  You can only update it
-with signed updates.
-
-If you'd like to also permanently disable signed updates, plug in your programmed Solo and run the following:
-
-```

+
+## Custom Attestation key
+
+The attestation key is used in the FIDO2 *makeCredential* or U2F *register* requests.  It signs
+newly generated credentials.  The certificate associated with the attestation key is output with newly created credentials.
+
+Platforms or services can use the attestation feature to enforce specific authenticators to be used.
+This is typically a use case for organizations and isn't seen in the wild for consumer use cases.
+
+Attestation keys are typically the same for at least 100K units of a particular authenticator model.
+This is so they don't contribute a significant fingerprint that platforms could use to identify the user.
+
+If you don't want to use the default attestation key that Solo builds with, you can create your own
+and program it.
+
+### Creating your attestation key pair
+
+Since we are generating keys, it's important to use a good entropy source.
+You can use the [True RNG on your Solo](/solo/solo-extras) to generate some good random numbers.
+
+```
+# Run for 1 second, then hit control-c
+solo key rng raw > seed.bin
+```
+
+First we will create a self signed key pair that acts as the root of trust.  This
+won't go on the authenticator, but will sign the keypair that does.
+
+Please change the root certification information as needed.  You may change the ECC curve.
+
+```
+curve=prime256v1
+
+country=US
+state=Maine
+organization=OpenSourceSecurity
+unit="Root CA"
+CN=example.com
+email=example@example.com
+
+# generate EC private key
+openssl ecparam -genkey -name "$curve" -out root_key.pem -rand seed.bin
+
+# generate a "signing request"
+openssl req -new -key root_key.pem -out root_key.pem.csr  -subj "/C=$country/ST=$state/O=$organization/OU=$unit/CN=example.com/emailAddress=$email"
+
+# self sign the request
+openssl x509 -trustout -req -days 18250  -in root_key.pem.csr -signkey root_key.pem -out root_cert.pem -sha256
+
+# convert to smaller size format DER
+openssl  x509 -in root_cert.pem -outform der -out root_cert.der
+
+# print out information and verify
+openssl x509 -in root_cert.pem -text -noout
+```
+
+You need to create a extended certificate for the device certificate to work with FIDO2.  You need to create this
+file, `v3.ext`, and add these options to it.
+
+```
+subjectKeyIdentifier=hash
+authorityKeyIdentifier=keyid,issuer
+basicConstraints=CA:FALSE
+keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
+```
+
+Now to generate & sign the attestation key pair that will go on your device, or maybe 100,000 devices :).
+Note you must use a prime256v1 curve for this step, and you must leave the unit/OU as "Authenticator Attestation".
+
+```
+country=US
+state=Maine
+organization=OpenSourceSecurity
+unit="Authenticator Attestation"
+CN=example.com
+email=example@example.com
+
+# generate EC private key
+openssl ecparam -genkey -name "$curve" -out device_key.pem -rand seed.bin
+
+# generate a "signing request"
+openssl req -new -key device_key.pem -out device_key.pem.csr -subj "/C=$country/ST=$state/O=$organization/OU=$unit/CN=example.com/emailAddress=$email"
+
+# sign the request
+openssl x509 -req -days 18250  -in device_key.pem.csr -extfile v3.ext -CA root_cert.pem -CAkey root_key.pem -set_serial 01 -out device_cert.pem -sha256
+
+# convert to smaller size format DER
+openssl  x509 -in device_cert.pem  -outform der -out device_cert.der
+
+# Verify the device certificate details
+openssl x509 -in device_cert.pem -text -noout
+```
+
+Let's verify that the attestation key and certificate are valid, and that they can be verified with the root key pair.
+
+```
+echo 'challenge $RANDOM' > chal.txt
+
+# check that they are valid key pairs
+openssl dgst -sha256 -sign device_key.pem -out sig.txt chal.txt
+openssl dgst -sha256 -verify  <(openssl x509 -in device_cert.pem  -pubkey -noout)  -signature sig.txt chal.txt
+
+openssl dgst -sha256 -sign "root_key.pem" -out sig.txt chal.txt
+openssl dgst -sha256 -verify  <(openssl x509 -in root_cert.pem  -pubkey -noout)  -signature sig.txt chal.txt
+
+# Check they are a chain
+openssl verify -verbose -CAfile "root_cert.pem" "device_cert.pem"
+```
+
+If the checks succeed, you are ready to program the device attestation key and certificate.
+
+### Programming an attestation key and certificate
+
+Convert the DER format of the device attestation certificate to "C" bytes using our utility script.  You may first need to
+first install prerequisite python modules (pip install -r tools/requirements.txt).
+
+```
+python tools/gencert/cbytes.py device_cert.der
+```
+
+Copy the byte string portion into the [`attestation.c` source file of Solo](https://github.com/solokeys/solo/blob/master/targets/stm32l432/src/attestation.c).  Overwrite the development or "default" certificate that is already there.
+
+Now [build the Solo firmware](/solo/building), either a secure or hacker build.  You will need to produce a bootloader.hex file and a solo.hex file.
+
+Print your attestation key in a hex string format.
+
+```
+python tools/print_x_y.py device_key.pem
+```
+
+Merge the bootloader.hex, solo.hex, and attestion key into one firmware file.
+
+```
+solo mergehex --attestation-key <attestation-key-hex-string> bootloader.hex solo.hex all.hex
+```
+
+Now you have a newly create `all.hex` file with a custom attestation key.  You can [program this all.hex file
+with Solo in DFU mode](/solo/programming#procedure).

+
+### Install ARM tools Linux
+
+1.  Download current [ARM tools] package: [gcc-arm-none-eabi-8-2018-q4-major-linux.tar.bz2].
+
+2.  Extract the archive.
+
+3.  Add full path to the `./bin` directory as first entry to the `$PATH` variable,
+    as in `~/gcc-arm/gcc-arm-none-eabi-8-2018-q4-major/bin/:$PATH`.
+
+### Install ARM tools OsX using brew package manager
+
+```bash
+brew tap ArmMbed/homebrew-formulae
+brew install arm-none-eabi-gcc
+```
+
+### Install flashing software
+
+ST provides a CLI flashing tool - `STM32_Programmer_CLI`. It can be downloaded directly from the vendor's site:
+1\. Go to [download site URL](https://www.st.com/content/st_com/en/products/development-tools/software-development-tools/stm32-software-development-tools/stm32-programmers/stm32cubeprog.html),
+go to bottom page and from STM32CubeProg row select Download button.
+2\. Unzip contents of the archive.
+3\. Run \*Linux setup
+4\. In installation directory go to ./bin - there the ./STM32_Programmer_CLI is located
+5\. Add symlink to the STM32 CLI binary to .local/bin. Make sure the latter it is in $PATH.
+
+If you're on OsX and installed the STM32CubeProg, you need to add the following to your path:
+
+```bash
+# ~/.bash_profile
+export PATH="/Applications/STMicroelectronics/STM32Cube/STM32CubeProgrammer/STM32CubeProgrammer.app/Contents/MacOs/bin/":$PATH
+```
+
+## Building and flashing
+
+### Building
+
+Please follow <https://docs.solokeys.io/solo/building/>, as the build way changes rapidly.
+Currently (8.1.19) to build the firmware, following lines should be executed
+
+```bash
+# while in the main project directory
+cd targets/stm32l432
+make cbor
+make build-hacker DEBUG=1
+```
+
+Note: `DEBUG=2` stops the device initialization, until a serial client will be attached to its virtual port.
+Do not use it, if you do not plan to do so.
+
+### Flashing via the Makefile command
+
+```bash
+# while in the main project directory
+# create Python virtual environment with required packages, and activate
+make venv
+. venv/bin/activate
+# Run flashing
+cd ./targets/stm32l432
+make flash
+ # which runs:
+ # flash: solo.hex bootloader.hex
+ #	python merge_hex.py solo.hex bootloader.hex all.hex (intelhex library required)
+ #	STM32_Programmer_CLI -c port=SWD -halt -e all --readunprotect
+ #	STM32_Programmer_CLI -c port=SWD -halt  -d all.hex -rst
+```
+
+### Manual flashing
+
+In case you already have a firmware to flash (named `all.hex`), please run the following:
+
+```bash
+STM32_Programmer_CLI -c port=SWD -halt -e all --readunprotect
+STM32_Programmer_CLI -c port=SWD -halt  -d all.hex -rst
+```
+
+## Testing

+# Programming
+
+This page documents how to update or program your Solo.
+
+## Prerequisites
+
+To program Solo, you'll likely only need to use our Solo tool.
+
+```python
+pip3 install solo-python
+```
+
+## Updating the firmware
+
+If you just want to update the firmware, you can run one of the following commands.
+Make sure your key [is in bootloader mode](/solo/bootloader-mode#solo-bootloader) first.
+
+```bash
+solo key update <--secure | --hacker>
+```
+
+You can manually install the [latest release](https://github.com/solokeys/solo/releases), or use a build that you made.
+
+```bash
+# If it's a hacker, it will automatically boot into bootloader mode.
+solo program bootloader <firmware.hex | firmware.json>
+```
+
+Note you won't be able to use `all.hex` or the `bundle-*.hex` builds, as these include the solo bootloader.  You shouldn't
+risk changing the Solo bootloader unless you want to make it a secure device, or [make other customizations]().
+
+## Updating a Hacker to a Secure Solo
+
+Updating a hacker to be a secure build overwrites the [Solo bootloader](/solo/bootloader-mode#solo-bootloader).
+So it's important to not mess this up or you may brick your device.
+
+You can use a firmware build from the [latest release](https://github.com/solokeys/solo/releases) or use
+a build that you made yourself.
+
+You need to use a firmware file that has the combined bootloader and application (or at the very least just the bootloader).
+This means using the `bundle-*.hex` file or the `all.hex` from your build.  If you overwrite the Solo flash with a missing bootloader,
+it will be bricked.
+
+We provide two types of bundled builds.  The `bundle-hacker-*.hex` build is the hacker build.  If you update with this,
+you will update the bootloader and application, but nothing will be secured.  The `bundle-secure-non-solokeys.hex`
+is a secured build that will lock your device and it will behave just like a Secure Solo.  The main difference is that
+it uses a "default" attestation key in the device, rather than the SoloKeys attestation key.  There is no security
+concern with using our default attestation key, aside from a privacy implication that services can distinguish it from Solo Secure.
+
+### Procedure
+
+1. Boot into DFU mode.
+
+        # Enter Solo bootloader
+        solo program aux enter-bootloader
+
+        # Enter DFU
+        solo program aux enter-dfu
+
+    The device should be turned off.
+
+2. Program the device
+
+        solo program dfu <bundle-secure-non-solokeys.hex | all.hex>
+
+    Double check you programmed it with bootloader + application (or just bootloader).
+    If you messed it up, simply don't do the next step and repeat this step correctly.
+
+3. Boot the device
+
+    Once Solo boots a secure build, it will lock the flash permantly from debugger access.  Also the bootloader
+    will only accept signed firmware updates.
+
+        solo program aux leave-dfu
+
+If you are having problems with solo tool and DFU mode, you could alternatively try booting into DFU
+by holding down the button while Solo is in bootloader mode.  Then try another programming tool that works
+with ST DFU:
+
+* STM32CubeProg
+* openocd
+* stlink
+
+Windows users need to install [libusb](https://sourceforge.net/projects/libusb-win32/files/libusb-win32-releases/1.2.6.0/)
+for solo-python to work with Solo's DFU.
+
+
+## Programming a Solo that hasn't been programmed
+
+A Solo that hasn't been programmed will boot into DFU mode.  You can program
+it by following a bootloader, or combined bootloader + application.
+
+```
+solo program dfu <bundle-*.hex | all.hex>
+```
+
+Then boot the device.  Make sure it has a bootloader to boot to.
+
+```
+solo program aux leave-dfu
+```
+
+## Disable signed firmware updates
+
+If you'd like to also permanently disable signed updates, plug in your programmed Solo and run the following:
+
+```bash
+# WARNING: No more signed updates.
+solo program disable-bootloader
+```
+
+You won't be able to update to any new releases.

+
+## Random number generation
+
+Solo contains a True Random Number Generator (TRNG).  A TRNG is a hardware based mechanism
+that leverages natural phenomenon to generate random numbers, which is can be better than a traditional
+RNG that has state and updates deterministically using cryptographic methods.
+
+You can easily access the TRNG stream on Solo using our python tool [solo-python](https://github.com/solokeys/solo-python).
+
+```
+solo key rng raw > random.bin
+```
+
+Or you can seed the state of the RNG on your kernel (/dev/random).

+```
+solo key rng feedkernel

-/**
- * @class MemoryMap
- *
- * Represents the contents of a memory layout, with main focus into (possibly sparse) blocks of data.
- *<br/>
- * A {@linkcode MemoryMap} acts as a subclass of
- * {@linkcode https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Map|Map}.
- * In every entry of it, the key is the starting address of a data block (an integer number),
- * and the value is the <tt>Uint8Array</tt> with the data for that block.
- *<br/>
- * The main rationale for this is that a .hex file can contain a single block of contiguous
- * data starting at memory address 0 (and it's the common case for simple .hex files),
- * but complex files with several non-contiguous data blocks are also possible, thus
- * the need for a data structure on top of the <tt>Uint8Array</tt>s.
- *<br/>
- * In order to parse <tt>.hex</tt> files, use the {@linkcode MemoryMap.fromHex} <em>static</em> factory
- * method. In order to write <tt>.hex</tt> files, create a new {@linkcode MemoryMap} and call
- * its {@linkcode MemoryMap.asHexString} method.
- *
- * @extends Map
- * @example
- * import MemoryMap from 'nrf-intel-hex';
- *
- * let memMap1 = new MemoryMap();
- * let memMap2 = new MemoryMap([[0, new Uint8Array(1,2,3,4)]]);
- * let memMap3 = new MemoryMap({0: new Uint8Array(1,2,3,4)});
- * let memMap4 = new MemoryMap({0xCF0: new Uint8Array(1,2,3,4)});
