Crate elliptic_curve

General purpose Elliptic Curve Cryptography (ECC) support, including types and traits for representing various elliptic curve forms, scalars, points, and public/secret keys composed thereof.

Minimum Supported Rust Version

Rust 1.51 or higher.

Minimum supported Rust version can be changed in the future, but it will be done with a minor version bump.
