[![Build Status](https://travis-ci.org/Keats/rust-jwt.svg)](https://travis-ci.org/Keats/rust-jwt)
|
|
|
|
|
|
|
|
## Dependencies
|
|
|
|
You will need to add `rustc-serialize` to your Cargo.toml in order to use this crate.
|
|
|
|
|
|
|
|
## How to use
|
|
|
|
There is a complete example in examples/claims.rs but here's a quick one.
|
|
|
|
|
|
|
|
### Encoding
|
|
|
|
```rust
|
|
|
|
// encode<T: Part>(claims: T, secret: String, algorithm: Algorithm) -> Result<String, Error>
|
|
|
|
let token = encode::<Claims>(my_claims, "secret".to_owned(), Algorithm::HS256);
|
|
|
|
```
|
|
|
|
In that example, `my_claims` is an instance of the Claims struct.
|
|
|
|
The struct you are using for your claims should derive `RustcEncodable` and `RustcDecodable`.
|
|
|
|
|
|
|
|
### Decoding
|
|
|
|
```rust
|
|
|
|
// decode<T: Part>(token: String, secret: String, algorithm: Algorithm) -> Result<T, Error>
|
|
|
|
let claims = decode::<Claims>(token.to_owned(), "secret".to_owned(), Algorithm::HS256);
|
|
|
|
```
|
|
|
|
In addition to the normal base64/json decoding errors, `decode` can return two custom errors:
|
|
|
|
|
|
|
|
- **InvalidToken**: if the token is not a valid JWT
|
|
|
|
- **InvalidSignature**: if the signature doesn't match
|
|
|
|
|
|
|
|
## Algorithms
|
|
|
|
Right now, only SHA256 is supported.
|
|
|
|
|
|
|
|
## Missing
|
|
|
|
The header is currently not customisable and therefore does not support things like kid right now.
|
|
|
|
|
|
|
|
