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. Additionally all
crates 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.
We recommend curve25519-dalek for a pure Rust Curve25519 library.
All crates in this repository support Rust 1.41 or higher. In future minimum supported Rust version can be changed, but it will be done with the minor version bump.
