//! Pure Rust implementation of Public-Key Cryptography Standards (PKCS) #1:
//!
//! RSA Cryptography Specifications Version 2.2 ([RFC 8017])
//!
//! ## About
//! This crate supports encoding and decoding RSA private and public keys
//! in either PKCS#1 DER (binary) or PEM (text) formats.
//!
//! PEM encoded RSA private keys begin with:
//!
//! ```text
//! -----BEGIN RSA PRIVATE KEY-----
//! ```
//!
//! PEM encoded RSA public keys begin with:
//!
//! ```text
//! -----BEGIN RSA PUBLIC KEY-----
//! ```
//!
//! # Minimum Supported Rust Version
//! This crate requires **Rust 1.51** at a minimum.
//!
//! [RFC 8017]: https://tools.ietf.org/html/rfc8017
