Module openssl::pkey [−][src]
Expand description
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

DiffieHellman

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 2048bit RSA public/private key pair and print the public key.
use openssl::rsa::Rsa;
use openssl::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());
