A JSON Web Token library.
If you don't care about that header as long as the header is verified, signing and verification can be done with just a few traits.
Claims can be any serde::Serialize type, usually derived with
serde_derive.
use hmac::{Hmac, Mac};
use jwt::SignWithKey;
use sha2::Sha256;
use std::collections::BTreeMap;
let key: Hmac<Sha256> = Hmac::new_from_slice(b"some-secret").unwrap();
let mut claims = BTreeMap::new();
claims.insert("sub", "someone");
let token_str = claims.sign_with_key(&key).unwrap();
assert_eq!(token_str, "eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJzb21lb25lIn0.5wwE1sBrs-vftww_BGIuTVDeHtc1Jsjo-fiHhDwR8m0");Claims can be any serde::Deserialize type, usually derived with
serde_derive.
use hmac::{Hmac, Mac};
use jwt::VerifyWithKey;
use sha2::Sha256;
use std::collections::BTreeMap;
let key: Hmac<Sha256> = Hmac::new_from_slice(b"some-secret").unwrap();
let token_str = "eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJzb21lb25lIn0.5wwE1sBrs-vftww_BGIuTVDeHtc1Jsjo-fiHhDwR8m0";
let claims: BTreeMap<String, String> = token_str.verify_with_key(&key).unwrap();
assert_eq!(claims["sub"], "someone");If you need to customize the header, you can use the Token struct. For
convenience, a Header struct is provided for all of the commonly defined
fields, but any type that implements JoseHeader can be used.
Both header and claims have to implement serde::Serialize.
use hmac::{Hmac, Mac};
use jwt::{AlgorithmType, Header, SignWithKey, Token};
use sha2::Sha384;
use std::collections::BTreeMap;
let key: Hmac<Sha384> = Hmac::new_from_slice(b"some-secret").unwrap();
let header = Header {
algorithm: AlgorithmType::Hs384,
..Default::default()
};
let mut claims = BTreeMap::new();
claims.insert("sub", "someone");
let token = Token::new(header, claims).sign_with_key(&key).unwrap();
assert_eq!(token.as_str(), "eyJhbGciOiJIUzM4NCJ9.eyJzdWIiOiJzb21lb25lIn0.WM_WnPUkHK6zm6Wz7zk1kmIxz990Te7nlDjQ3vzcye29szZ-Sj47rLNSTJNzpQd_");Both header and claims have to implement serde::Deserialize.
use hmac::{Hmac, Mac};
use jwt::{AlgorithmType, Header, Token, VerifyWithKey};
use sha2::Sha384;
use std::collections::BTreeMap;
let key: Hmac<Sha384> = Hmac::new_from_slice(b"some-secret").unwrap();
let token_str = "eyJhbGciOiJIUzM4NCJ9.eyJzdWIiOiJzb21lb25lIn0.WM_WnPUkHK6zm6Wz7zk1kmIxz990Te7nlDjQ3vzcye29szZ-Sj47rLNSTJNzpQd_";
let token: Token<Header, BTreeMap<String, String>, _> = VerifyWithKey::verify_with_key(token_str, &key).unwrap();
let header = token.header();
let claims = token.claims();
assert_eq!(header.algorithm, AlgorithmType::Hs384);
assert_eq!(claims["sub"], "someone");A Store can be used to represent a collection of keys indexed by key id. Right now, this is only automatically implemented for BTreeMap and HashMap with Borrow<str> keys. If specialization lands then it will be implemented for all Index<&str> traits as it was before.
For the trait SignWithStore, the key id will be automatically added to the header for bare claims.
Because claims do not have a way to specify key id, a tuple of key id and claims is necessary. For
tokens, the header's key id will be used to get the key.
For the trait VerifyWithStore, the key id from the deserialized header will be used to choose the key
to use.
use hmac::{Hmac, Mac};
use jwt::{Header, SignWithStore, Token, VerifyWithStore};
use sha2::Sha512;
use std::collections::BTreeMap;
let mut store: BTreeMap<_, Hmac<Sha512>> = BTreeMap::new();
store.insert("first_key", Hmac::new_from_slice(b"first").unwrap());
store.insert("second_key", Hmac::new_from_slice(b"second").unwrap());
let mut claims = BTreeMap::new();
claims.insert("sub", "someone");
let token_str = ("second_key", claims).sign_with_store(&store).unwrap();
assert_eq!(token_str, "eyJhbGciOiJIUzUxMiIsImtpZCI6InNlY29uZF9rZXkifQ.eyJzdWIiOiJzb21lb25lIn0.9gALQon5Mk8r4BjOZ2SJQlauGmT4WUhpN152x9dfKvkPON1VwEN09Id8vjQ0ABlfLJUTVNP36dsdrpYEZDLUcw");
let verified_token: Token<Header, BTreeMap<String, String>, _> = token_str.verify_with_store(&store).unwrap();
assert_eq!(verified_token.claims()["sub"], "someone");
assert_eq!(verified_token.header().key_id.as_ref().unwrap(), "second_key");Pure Rust HMAC is supported through RustCrypto. Implementations of RSA and ECDSA signatures are supported through OpenSSL, which is not enabled by default. OpenSSL types must be wrapped in the PKeyWithDigest struct.
