LightECC is a lightweight Python library for Elliptic Curve Cryptography (ECC) arithmetic. It provides support for various elliptic curve forms, including Weierstrass, Koblitz, and Edwards, along with many pre-defined curves. The library simplifies fundamental ECC operations such as point addition, subtraction, scalar multiplication, and division. As of its current version 0.0.5, LightECC aims to make ECC operations accessible without requiring deep understanding of the underlying mathematical principles. The library appears to be actively maintained, with recent updates.

This quickstart demonstrates how to initialize a LightECC object, retrieve the base point, and perform basic elliptic curve point arithmetic operations like addition, subtraction, and scalar multiplication. It also shows an example of point division, noting its computational complexity.
Avoid using point division in performance-critical or real-time applications. For cryptographic schemes, typically the ECDLP hardness is exploited, not solved.
Refer to the official LightECC documentation or source code for the list of supported `curve_name` values and their corresponding `form_name` to ensure proper and secure curve instantiation.
Ensure the package is installed using `pip install lightecc`. Verify the import statement is `from lightecc import LightECC`.
Check the LightECC documentation or the object's available methods (e.g., using `dir(ec)`) to ensure the correct attribute or method name is used.
Ensure that arithmetic operations are performed between compatible LightECC `Point` objects or between a `Point` and a scalar (for multiplication). For point addition/subtraction, both operands must be `Point` instances.
