## About

Pure Rust implementation of [SEC1: Elliptic Curve Cryptography] encoding
formats including ASN.1 DER-serialized private keys (also described in
[RFC5915]) as well as the `Elliptic-Curve-Point-to-Octet-String` and
`Octet-String-to-Elliptic-Curve-Point` encoding algorithms.

## Minimum Supported Rust Version

This crate requires **Rust 1.57** at a minimum.

We may change the MSRV in the future, but it will be accompanied by a minor
version bump.
