Crate detached_jws

Encoding, decoding, signing and verification (Detached JWS)

Signing and verifying is done through the Sign and Verify traits.

Example:

use openssl::pkey::PKey;
use openssl::rsa::Rsa;
use openssl::{hash::MessageDigest};
use openssl::{
    rsa::Padding,
    sign::{Signer, Verifier},
};
use serde_json::{json, Map, Value};
 
let keypair = PKey::from_rsa(Rsa::generate(2048).unwrap()).unwrap();
 
let mut signer = Signer::new(MessageDigest::sha256(), &keypair).unwrap();
signer.set_rsa_padding(Padding::PKCS1_PSS).unwrap();
 
let mut header = Map::new();
header.insert("custom".to_owned(), json!("custom_value"));
 
let payload = vec![0, 1, 2, 3, 4, 5, 6];
 
let jws = detached_jws::serialize(
    "PS256".to_owned(),
    header,
    &mut payload.as_slice(),
    &mut signer,
)
.unwrap();
 
let mut verifier = Verifier::new(MessageDigest::sha256(), &keypair).unwrap();
verifier.set_rsa_padding(Padding::PKCS1_PSS).unwrap();
 
let verified_headers =
    detached_jws::deserialize(&jws, &mut payload.as_slice(), &mut verifier).unwrap();
 
assert_eq!(
    verified_headers.get("custom").unwrap().as_str().unwrap(),
    "custom_value"
);
