Okta JWT Verifier for Rust

Install

Cargo.toml

toml [dependencies] okta-jwt-verifier = { git = "https://gitlab.com/06chaynes/okta-jwt-verifier.git", branch = "master" }

Basic Usage

This example attempts to retrieve the keys from the provided Okta authorization server, decodes the token header to identify the key id, attempts to find a matching key, attempts to decode the token, and finally attempts to deserialize the claims.

This method will attempt to retrieve the keys upon each request.

```rust use oktajwtverifier::verify; use serde::{Deserialize, Serialize};

[derive(Serialize, Deserialize)]

pub struct Claims { pub iss: String, pub sub: String, pub scp: Vec, pub cid: String, pub uid: String, pub exp: u64, pub iat: u64, }

let token = "token"; let issuer = "https://your.domain/oauth2/default";

verify::(&issuer, &token).await?; ```

Advanced Usage

This example matches the basic example in function but would allow for caching of the keys

```rust use oktajwtverifier::{verify, token, key, JWK, JWKS}; use jsonwebkey::JsonWebKey; use serde::{Deserialize, Serialize};

[derive(Serialize, Deserialize)]

pub struct Claims { pub iss: String, pub sub: String, pub scp: Vec, pub cid: String, pub uid: String, pub exp: u64, pub iat: u64, }

let token = "token"; let issuer = "https://your.domain/oauth2/default";

let kid: String = token::keyid(&token)?; let jwks: JWKS = key::get(&issuer).await?; let jwk: Option<&JWK> = jwks.whereid(&kid); match jwk { Some(keyjwk) => { let key: JsonWebKey = serdejson::tostring(&keyjwk)?.parse()?; let claims = token::decode::(&token, key).await?; } None => {} }

```

Development

Testing

• Note that this requires an internet connection

First copy the example config to a new file:

sh cp .env_example .env

Update the ISSUER variable to reflect your environment (authorization host). Also set TEST_TOKEN to a JWT to test against, then run the tests.

sh cargo test
