Stark Curve
Pure Rust implementation of Stark Curve. Provides basic elliptic curve arithmetic backed by
primeorder, elliptic-curve, and ff crates. #![no_std] friendly.
Curve parameters
As specified in a stark curve specs, this crate provides an implementation of a curve defined by equation:
$$y^2 = x^3 + \alpha x + \beta \pmod p$$
where:
$$ \begin{aligned} \alpha &= 1\\ \beta &= 3141592653589793238462643383279502884197169399375105820974944592307816406665\\ p &= 3618502788666131213697322783095070105623107215331596699973092056135872020481\\ &= 2^{251} + 17 \cdot 2^{192} + 1 \end{aligned} $$
Also, curve order $n$, which is not mentioned in the specs but can be found here:
$n = 3618502788666131213697322783095070105526743751716087489154079457884512865583$
Both $p$ and $n$ are prime.
Security
This crate doesn't implement any sensitive cryptography code. Instead, we delegate scalar arithmetic to ff crate, and elliptic point arithmetic to primeorder crate, which are considered to be heavily used and tested.
