Trait Implementations§

source§

impl Algorithm for Es256

§

type SigningKey = SigningKey<NistP256>

Key used when issuing new tokens.
§

type VerifyingKey = VerifyingKey<NistP256>

Key used when verifying tokens. May coincide with Self::SigningKey for symmetric algorithms (e.g., HS*).
§

type Signature = Signature<NistP256>

Signature produced by the algorithm.
source§

fn name(&self) -> Cow<'static, str>

Returns the name of this algorithm, as mentioned in the alg field of the JWT header.
source§

fn sign( &self, signing_key: &Self::SigningKey, message: &[u8] ) -> Self::Signature

Signs a message with the signing_key.
source§

fn verify_signature( &self, signature: &Self::Signature, verifying_key: &Self::VerifyingKey, message: &[u8] ) -> bool

Verifies the message against the signature and verifying_key.
source§

source§

impl SigningKey<Es256> for SigningKey

source§

fn from_slice(raw: &[u8]) -> Result<Self>

source§

fn to_verifying_key(&self) -> VerifyingKey

Converts a signing key to a verification key.
source§

fn as_bytes(&self) -> SecretBytes<'_>

Returns the key as raw bytes. Read more
source§

impl VerifyingKey<Es256> for VerifyingKey

source§

fn as_bytes(&self) -> Cow<'_, [u8]>

Serializes the key as a 33-byte compressed form.

source§

fn from_slice(raw: &[u8]) -> Result<Self>

Creates a key from raw bytes. Returns an error if the bytes do not represent a valid key.

where A: Algorithm,

source§

fn token<T>( &self, header: &Header<impl Serialize>, claims: &Claims<T>, signing_key: &<A as Algorithm>::SigningKey ) -> Result<String, CreationError>
where T: Serialize,

Creates a new token and serializes it to string.
source§

fn compact_token<T>( &self, header: &Header<impl Serialize>, claims: &Claims<T>, signing_key: &<A as Algorithm>::SigningKey ) -> Result<String, CreationError>
where T: Serialize,

Available on crate feature ciborium only.
Creates a new token with CBOR-encoded claims and serializes it to string.
source§

fn validator<T, 'a>( &'a self, verifying_key: &'a <A as Algorithm>::VerifyingKey ) -> Validator<'a, A, T>
