imgtool: Improve ECDSA key generation

This patch improves the existing ECDSA key generation feature
in the imgtool by:
 - Fix a bug in the 'minimal' representation of PKCS#8 keys where
   the resulting ASN.1 DER encoding is not compliant
 - Add the option to export ECDSA private keys in SEC1 format by
   providing a command line option -f or --format that can be
   'openssl' (for SEC1 format) or 'pkcs8'. This format ends up in
   key encodings which are generally smaller than PKCS#8.

MCUboot

Package on PyPI Coverity Scan Build Status Build Status (Sim) Build Status (Mynewt) Publishing Status (imgtool) Build Status (Travis CI) Apache 2.0

This is MCUboot version 1.10.0-dev

MCUboot is a secure bootloader for 32-bits microcontrollers. It defines a common infrastructure for the bootloader and the system flash layout on microcontroller systems, and provides a secure bootloader that enables easy software upgrade.

MCUboot is not dependent on any specific operating system and hardware and relies on hardware porting layers from the operating system it works with. Currently, MCUboot works with the following operating systems and SoCs:

RIOT is supported only as a boot target. We will accept any new port contributed by the community once it is good enough.

MCUboot How-tos

See the following pages for instructions on using MCUboot with different operating systems and SoCs:

There are also instructions for the Simulator.

Roadmap

The issues being planned and worked on are tracked using GitHub issues. To give your input, visit MCUboot GitHub Issues.
