Python Elliptic Curve cryptography Side-Channel Analysis toolkit.

For more info, see the docs.

Functionality

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 currently provides:

pyecsca consists of three packages:
