Struct jwt_compact_preview::alg::Ed25519

pub struct Ed25519;

Integrity algorithm using digital signatures on the Ed25519 elliptic curve.

The name of the algorithm is specified as EdDSA as per the IANA registry. Use with_specific_name() to switch to non-standard Ed25519.

This type is available if the crate is built with the ed25519-compact feature.

Implementations

impl Ed25519

pub fn with_specific_name() -> Renamed<Self>

Creates an algorithm instance with the algorithm name specified as Ed25519. This is a non-standard name, but it is used in some apps.

pub fn generate<R: CryptoRng + RngCore>(
    &self,
    rng: &mut R
) -> (Ed25519SigningKey, Ed25519VerifyingKey)

Generate a new key pair.

Trait Implementations

impl Algorithm for Ed25519

type SigningKey = Ed25519SigningKey

Key used when issuing new tokens.

type VerifyingKey = Ed25519VerifyingKey

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

type Signature = Signature

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 Clone for Ed25519

fn clone(&self) -> Ed25519

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Ed25519

impl Debug for Ed25519

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

Formats the value using the given formatter.

impl Hash for Ed25519

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl PartialEq<Ed25519> for Ed25519

fn eq(&self, other: &Ed25519) -> bool
