Struct rustwt::Encoder

pub struct Encoder { /* fields omitted */ }

Low level structure for encoding JWT. Use this struct if you want to have full control over the payload used for your JWT. In most scenarios, you are better of using id_token though.

Example public key signature

use rustwt::{Payload,Encoder,Algorithm,Decoder,Value};
// you can use RSA keys as well. Just adjust the algorithm.
let ec_private_key: &str = include_str!("../test/ec_x9_62_prime256v1.private.key.pem");
let ec_public_key: &str = include_str!("../test/ec_x9_62_prime256v1.public.key.pem");
let mut p1 = Payload::new();
p1.insert("key12".to_string(), Value::String("val1".to_string()));
p1.insert("key22".to_string(), Value::String("val2".to_string()));
p1.insert("key33".to_string(), Value::String("val3".to_string()));
let encoder = Encoder::from_raw_private_key(ec_private_key, Algorithm::ES256).unwrap();
let decoder = Decoder::from_pem(ec_public_key).unwrap();
let jwt1 = encoder.encode(p1.clone()).expect("could not encode token");
let maybe_res = decoder.decode(jwt1);

Example hmac

use rustwt::{Payload,Encoder,Algorithm,Decoder,Value};
let secret: &str = "secret123";
let mut p1 = Payload::new();
p1.insert("key12".to_string(), Value::String("val1".to_string()));
p1.insert("key22".to_string(), Value::String("val2".to_string()));
p1.insert("key33".to_string(), Value::String("val3".to_string()));
let encoder = Encoder::from_raw_private_key(secret, Algorithm::HS256).unwrap();
let decoder = Decoder::from_hmac_secret(secret).unwrap();
let jwt1 = encoder.encode(p1.clone()).expect("could not encode token");
let maybe_res = decoder.decode(jwt1);

Methods

impl Encoder

fn from_raw_private_key<T: ?Sized + AsRef<[u8]>>(
    raw_key: &T,
    alg: Algorithm
) -> Result<Encoder, Error>

Create a new Encoder from a raw private key and an Algorithm. The private key can either be a HMAC or a PEM encoded RSA/EC key.

fn from_private_key(pkey: PKey, alg: Algorithm) -> Encoder

Create a new Encoder from a PKey struct.

fn encode(&self, payload: Payload) -> Result<String, Error>

Encodes a payload into a JWT.
