JWT signing algorithm.

Associated Types

type SigningKey

Key used when issuing new tokens.

type VerifyingKey

Key used when verifying tokens. May coincide with 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.
