rsa-der

A simple crate to encode and decode RSA public keys to DER-encoded bytes.

See the documentation for examples.

lib.rs:

A simple crate to encode and decode DER-formatted public RSA keys.

Public keys are passed to and returned from functions simply using the n and e components, so any RSA library can be used in conjunction with this crate.

Examples

Convert an RSA public key to DER bytes:

# use rsa::{RSAPrivateKey, PublicKey};
use rand::rngs::OsRng;
# fn generate_key() -> impl PublicKey {
# let mut rng = OsRng::new().unwrap();
# let key = RSAPrivateKey::new(&mut rng, 2048).unwrap();
# key
# }

let key = generate_key();
let der_bytes = rsa_der::public_key_to_der(&key.n().to_bytes_be(), &key.e().to_bytes_be());
