RustCrypto: Elliptic Curves Rust Version Project Chat dependency status

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.

Crates

NOTE: Most crates have field/point arithmetic implementations gated under the arithmetic cargo feature as noted in the arithmetic column below:
