//! Public/private key processing.
|
|
//!
|
|
//! Asymmetric public key algorithms solve the problem of establishing and sharing
|
|
//! secret keys to securely send and receive messages.
|
|
//! This system uses a pair of keys: a public key, which can be freely
|
|
//! distributed, and a private key, which is kept to oneself. An entity may
|
|
//! encrypt information using a user's public key. The encrypted information can
|
|
//! only be deciphered using that user's private key.
|
|
//!
|
|
//! This module offers support for five popular algorithms:
|
|
//!
|
|
//! * RSA
|
|
//!
|
|
//! * DSA
|
|
//!
|
|
//! * Diffie-Hellman
|
|
//!
|
|
//! * Elliptic Curves
|
|
//!
|
|
//! * HMAC
|
|
//!
|
|
//! These algorithms rely on hard mathematical problems - namely integer factorization,
|
|
//! discrete logarithms, and elliptic curve relationships - that currently do not
|
|
//! yield efficient solutions. This property ensures the security of these
|
|
//! cryptographic algorithms.
|
|
//!
|
|
//! # Example
|
|
//!
|
|
//! Generate a 2048-bit RSA public/private key pair and print the public key.
|
|
//!
|
|
//! ```rust
|
|
//! use boring2::rsa::Rsa;
|
|
//! use boring2::pkey::PKey;
|
|
//! use std::str;
|
|
//!
|
|
//! let rsa = Rsa::generate(2048).unwrap();
|
|
//! let pkey = PKey::from_rsa(rsa).unwrap();
|
|
//!
|
|
//! let pub_key: Vec<u8> = pkey.public_key_to_pem().unwrap();
|
|
//! println!("{:?}", str::from_utf8(pub_key.as_slice()).unwrap());
|
|
//! ```
