Struct jwt_compact::alg::Es256

pub struct Es256;

Available on crate feature p256 only.

ES256 signing algorithm. Implements elliptic curve digital signatures (ECDSA) on the secp256r1 curve (aka P-256).

Trait Implementations

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.

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.

impl Debug for Es256

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Es256

fn default() -> Es256

Returns the “default value” for a type.

impl SigningKey<Es256> for SigningKey

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.

fn to_verifying_key(&self) -> VerifyingKey

Converts a signing key to a verification key.

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

Returns the key as raw bytes.

impl VerifyingKey<Es256> for VerifyingKey

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

Serializes the key as a 33-byte compressed form.

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.
