A JWT library for rust using serde, serde_json and openssl.
## Documentation
- [Documentation](https://commandline.github.io/medallion/)
## Usage
The library provides a `Token` type that wraps headers and claims.
```rust
extern crate medallion;
use std::default::Default;
use medallion::{
Header,
DefaultPayload,
Token,
};
fn main() {
// will default to Algorithm::HS256
let header: Header<()> = Default::default();
let payload = DefaultPayload {
iss: Some("example.com".into()),
sub: Some("Random User".into()),
..Default::default()
};
let token = Token::new(header, payload);
token.sign(b"secret_key").unwrap();
}
```
The `Header` struct contains all of the headers of the JWT. It requires that a supported algorithm (`HS256`, `HS384`, `HS512`, `RS256`, `RS384`, and `RS512`) be specified. It requires a type for additional header fields. That type must implement serde's `Serialize` and `Deserialize` as well as `PartialEq`. These traits can usually be derived, e.g. `#[derive(PartialEq, Serialize, Deserialize)`.
```rust
extern crate medallion;
use std::default::Default;
use serde::{Serialize, Deserialize};
use medallion::{Header, DefaultPayload, Token};
#[derive(Debug, Serialize, Deserialize, PartialEq)]
struct CustomHeaders {
kid: String,
typ: String,
}
fn main() {
let header = Header {
headers: CustomHeaders {
kid: "0001",)
typ: "JWT",)
}
..Default::default()
}
let payload = DefaultPayload {
iss: Some("example.com".into()),
sub: Some("Random User".into()),
..Default::default()
};
let token = Token::new(header, payload);
token.sign(b"secret_key").unwrap();
}
```
The `Payload` struct contains all of the claims of the JWT. It provides the set of registered, public claims. Additional claims can be added by constructing the `Payload` with a generically typed value. That value's type must implement serde's `Serialize` and `Deserialize` as well as `PartialEq`. These traits can usually be derived, e.g. `#[derive(PartialEq, Serialize, Deserialize)`. A convenience type, `DefaultPayload`, is provided that binds the generic parameter of `Payload` to an empty tuple type.
```rust
extern crate medallion;
use std::default::Default;
use serde::{Serialize, Deserialize};
use medallion::{Header, DefaultPayload, Token};
#[derive(Debug, Serialize, Deserialize, PartialEq)]
struct CustomHeaders {
kid: String,
typ: String,
}
#[derive(Debug, Serialize, Deserialize, PartialEq)]
struct CustomClaims {
user_id: u64,
email: String,
}
fn main() {
let header = Header {
headers: CustomHeaders {
kid: "0001",)
typ: "JWT",)
}
..Default::default()
}
let payload = DefaultPayload {
iss: Some("example.com".into()),
sub: Some("Random User".into()),
claims: CustomClaims {
user_id: 1234,
email: "random@example.com",
}
..Default::default()
};
let token = Token::new(header, payload);
token.sign(b"secret_key").unwrap();
}
```
