Struct DefaultVerifier 

pub struct DefaultVerifier;

A JwsVerifier over RustCrypto: ed25519-dalek for EdDSA, p256 for ES256, k256 for ES256K (feature secp256k1) and rsa for RS256 and PS256 (feature rsa).

ES384 is in the JwsAlgorithm vocabulary but not implemented here; verifying it returns VerificationError::UnsupportedAlgorithm.

Before the signature is checked, the key’s own restrictions are: a key whose alg names another algorithm, whose use is not sig or whose key_ops lacks verify is rejected.

Examples

use identity_kit::jose::{DefaultVerifier, Jwk, JwsAlgorithm, JwsVerifier};

// RFC 8037 Appendix A.4 and A.5.
let key: Jwk = serde_json::from_str(
    r#"{"kty":"OKP","crv":"Ed25519","x":"11qYAYKxCrfVS_7TyWQHOg7hcvPapiMlrwIaaPcHURo"}"#,
)?;
let token = "eyJhbGciOiJFZERTQSJ9.RXhhbXBsZSBvZiBFZDI1NTE5IHNpZ25pbmc.\
             hgyY0il_MGCjP0JzlnLWG1PPOt7-09PGcvMg3AIbQR6dWbhijcNR4ki4iylGjg5BhVsPt9g7sVvpAr_MuM0KAg";
let jws = identity_kit::jose::CompactJws::decode(token)?;
DefaultVerifier.verify(JwsAlgorithm::EdDSA, jws.signing_input(), jws.signature(), &key)?;
