Jochen Hoenicke 286ee0525c PIN handling - constant time. 
This diff contains three changes.
1. Make timing isPinCorrect independent of storage.pin, to avoid timing attacks
2. Only update failed PIN counter if the user entered a PIN.
   Of course, the fail counter is still incremented, before the PIN is checked.
3. Don't cache the PIN, but just the fact that the PIN was entered.  The
   cache should be in sync with storage.pin in any case.

TREZOR Firmware
===============

http://bitcointrezor.com/

How to build Trezor firmware?
-----------------------------

1. Install Docker (from docker.com or from your distribution repositories)
2. ``git clone https://github.com/trezor/trezor-mcu.git``
3. ``cd trezor-mcu``
4. ``./firmware-docker-build.sh``

This creates trezor.bin in current directory and prints its fingerprint at the last line of the build log.

How to get fingerprint of firmware signed and distributed by SatoshiLabs?
-------------------------------------------------------------------------

1. Pick version of firmware binary listed on https://mytrezor.com/data/firmware/releases.json
2. Download it: ``wget -O trezor.signed.bin.hex https://mytrezor.com/data/firmware/trezor-1.1.0.bin.hex``
3. ``xxd -r -p trezor.signed.bin.hex trezor.signed.bin``
4. ``./firmware-fingerprint.sh trezor.signed.bin``

Step 4 should produce the same sha256 fingerprint like your local build.

The reasoning for ``firmware-fingerprint.sh`` script is that signed firmware has special header holding signatures themselves, which must be avoided while calculating the fingerprint.
