What Is tinyec

This section introduces what is tinyec - a tiny library to perform arithmetic operations on elliptic curves in pure Python.

**What Is tinyec?**
tinyec is a tiny library to perform arithmetic operations on elliptic
curves in pure Python.
It is not a library suitable for production.
It is useful for security professionals to understand the inner workings
of EC, and be able to play with pre-defined curves.

There are 2 main classes in tinyec:

- Curve(), which describes an elliptic curve in a finite field.
- Point(), which describes a point belonging to an EC.

tinyec also supports some named curves: brainpoolP160r1, brainpoolP192r1, brainpoolP224r1, brainpoolP256r1, brainpoolP320r1, brainpoolP384r1, brainpoolP512r1, secp192r1, secp224r1, secp256r1, secp384r1, secp521r1
