//! Pure Rust implementations of the cryptographic traits.
//!
//! Most applications using this crate should use these implementations.
//! Alternative implementations can be useful on targets like wasm and
//! on-chain environments, where code size is at a premium and a faster
//! platform-native cryptographic API is available.
