“Elliptic Curves Calculator” is a practical application designed to assist students in simplifying complex calculations related to cryptography. This app allows users to perform various operations related to elliptic curves and show detailed step-by-step solutions, which is particularly helpful for solving homework assignments or understanding cryptographic concepts.

The app provides the following features:
* Addition between two points: Users can perform addition of two points on an elliptic curve using this function.
* Calculation of the curve’s order: The app enables users to calculate the order of a given elliptic curve.
* Double-And-Add Algorithm: By implementing the Double-And-Add Algorithm, users can efficiently perform multiplications on elliptic curves.
* Support for ECDH and ECDSA: The app offers functions to support Elliptic Curve Diffie-Hellman (ECDH) key exchange and the Elliptic Curve Digital Signature Algorithm (ECDSA) for generating and verifying digital signatures.
* Input validation and support for long integers: The app ensures that the input values are correct and supports long integers for precise calculations.

It is important to emphasize that “Elliptic Curves Calculator” has been developed exclusively for educational purposes, aiming to assist students with their homework and understanding of elliptic curves in cryptography.
