Trait Implementations

impl Clone for HS256

fn clone(&self) -> HS256

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HS256

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for HS256

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Drop for HS256

fn drop(&mut self)

Executes the destructor for this type.

impl Key for HS256

const ALG: &'static str = "HS256"

value for alg in the JWT header

fn check_alg(alg: &str) -> Result<(), Error>

Checks that alg equals Self::ALG.

impl PartialEq for HS256

fn eq(&self, other: &HS256) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for HS256

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl SigningKey for HS256

Implements signing of JWTs using the sha256-hmac.

use base64ct::{Base64UrlUnpadded, Encoding as _};

// Example A.1.1 of RFC 7515

    "dBjftJeZ4CVP-mB92K27uhbUJU1p1r_wW1gFWFOEjXk");

type Signature = GenericArray<u8, <CoreWrapper<CtVariableCoreWrapper<Sha256VarCore, UInt<UInt<UInt<UInt<UInt<UInt<UTerm, B1>, B0>, B0>, B0>, B0>, B0>, OidSha256>> as OutputSizeUser>::OutputSize>

The result of signing, e.g. [u8; 32].

fn sign(&self, s: &[u8]) -> Result<Self::Signature>

Returns a (non-base64-encoded) signature on s.

fn jwk(&self) -> Value

Returns JSON Web Key description of the associated public key.

impl VerifyingKey for HS256

use pubhubs::misc::jwt::{HS256, VerifyingKey};
use base64ct::{Base64UrlUnpadded, Encoding as _};

// Example A.1.1 of RFC 7515
