#![doc = include_str!("../README.md")]

//! # Usage
//! The following example demonstrates how to use an OID as the `parameters`
//! of an [`AlgorithmIdentifier`].
//!
//! Borrow the [`ObjectIdentifier`] first then use [`der::Any::from`] or `.into()`:
//!
//! ```
//! use spki::{AlgorithmIdentifier, ObjectIdentifier, der::Any};
//!
//! let alg_oid = "1.2.840.10045.2.1".parse::<ObjectIdentifier>().unwrap();
//! let params_oid = "1.2.840.10045.3.1.7".parse::<ObjectIdentifier>().unwrap();
//!
//! let alg_id = AlgorithmIdentifier {
//!     oid: alg_oid,
//!     parameters: Some(Any::from(&params_oid))
//! };
//! ```
