**Py**\ thon **E**\ lliptic **C**\ urve cryptography **S**\ ide-**C**\ hannel **A**\ nalysis toolkit.
**pyecsca** aims to fill a gap in SCA tooling for Elliptic Curve Cryptography, it focuses on
black-box implementations of ECC and presents a way to extract implementation information
about a black-box implementation of ECC through side-channels. The main goal of **pyecsca**
is to be able to reverse engineer the curve model, coordinate system, addition formulas, scalar
multiplier and even finite-field implementation details.
It is currently in an alpha stage of development and thus only provides:
.. card:: Enumeration
Enumeration of millions of possible ECC implementation configurations (see :doc:`notebook/configuration_space`)
.. card:: Simulation
Simulation and execution tracing of key generation, ECDH and ECDSA (see :doc:`notebook/simulation`)
.. card:: Code generation
Synthesis of C implementations of ECC for embedded devices, given any implementation configuration (see :doc:`notebook/codegen`),
CPU-level simulation of implementations (see :doc:`notebook/simulator`)
.. card:: Trace acquisition
Trace acquisition using PicoScope/ChipWhisperer oscilloscopes (see :doc:`notebook/measurement`)
.. card:: Trace processing
Trace processing capabilities, e.g. signal-processing, filtering, averaging, cutting, aligning (:doc:`api/pyecsca.sca`)
.. card:: Trace visualization
Trace visualization using holoviews and datashader (see :doc:`notebook/visualization`)
.. card:: Smartcard communication
Communication via PCSC/LEIA with a smartcard target (see :doc:`notebook/smartcards`)
**pyecsca** consists of three repositories:
.. grid:: 3
.. grid-item-card:: Core
The `core <https://github.com/J08nY/pyecsca>`_ package contains the core of the
functionality, except the code generation and notebooks.
.. grid-item-card:: Codegen
The `codegen <https://github.com/J08nY/pyecsca-codegen>`_ package contains
the code generation functionality.
.. grid-item-card:: Notebook
The `notebook <https://github.com/J08nY/pyecsca-notebook>`_ repository contains
example notebooks that showcase functionality of the toolkit.
:fas:`book` Notebooks
=========================
The notebooks below contain a showcase of what is possible using **pyecsca** and
are the best source of documentation on how to use **pyecsca**.

*pyecsca* contains data from the `Explicit-Formulas Database`_ by Daniel J. Bernstein and Tanja Lange.
The data was partially changed, to make working with it easier. It is available on Github at `crocs-muni/efd`_.
It uses `ChipWhisperer`_ as one of its targets. It also supports working with Riscure_ Inspector trace sets, which are of a proprietary format.
.. dropdown:: Testing & Development
See the Makefile for tests, performance measurement, codestyle and type checking commands.
Use black_ for code-formatting.
