1//! OpenPGP native adapters for uselesskey fixtures.
2//!
3//! Provides conversions to native [`pgp`] crate key types from
4//! [`PgpKeyPair`](crate::PgpKeyPair) generated fixtures.
5//!
6//! Gated behind the `native` Cargo feature so consumers that only want
7//! the armored/binary byte surface owned by this crate are not pulled
8//! into the native parser surface.
