Introduction

Bitpacker or bpak for short is a tool and library for creating firmware archives that can be cryptographically signed, support custom metadata and enable advanced update schemes. Bitpacker is primarily designed for embedded systems.

Embedded systems are often composed of several software components, for example: bootloader, kernel, file systems, device configuration, third party applications, etc. It is common to have many different formats and tools for the various components.

One of the main goals with bitpacker is to reduce the number of tools and formats required to manage these components.
