        signing_key: &Self::SigningKey,

}

JWT signing algorithm.

Required Associated Types

type SigningKey

Key used when issuing new tokens.

type VerifyingKey

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

type Signature: AlgorithmSignature

Signature produced by the algorithm.

Required Methods

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

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

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

Signs a message with the signing_key.

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

Verifies the message against the signature and verifying_key.
