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.
All curves reside in the separate crates and implemented using traits from
the elliptic-curve crate.
Crates in this repo do not require the standard library (i.e. no_std capable)
and can be easily used for bare-metal or WebAssembly programming.

NOTE: Some crates contain field/point arithmetic implementations gated under the
arithmetic cargo feature as noted above.
Please see our tracking issue for additional elliptic curves if you are interested in curves beyond the ones listed here.
All crates in this repository support Rust 1.61 or higher.
Minimum supported Rust version can be changed in the future, but it will be done with a minor version bump.
All crates licensed under either of
