Struct jsonwebtoken::Header

pub struct Header {
    pub typ: Option<String>,
    pub alg: Algorithm,
    pub cty: Option<String>,
    pub jku: Option<String>,
    pub jwk: Option<Jwk>,
    pub kid: Option<String>,
    pub x5u: Option<String>,
    pub x5c: Option<Vec<String>>,
    pub x5t: Option<String>,
    pub x5t_s256: Option<String>,
}

A basic JWT header, the alg defaults to HS256 and typ is automatically set to JWT. All the other fields are optional.

Fields

typ: Option<String>

The type of JWS: it can only be “JWT” here

Defined in RFC7515#4.1.9.

alg: Algorithm

The algorithm used

Defined in RFC7515#4.1.1.

cty: Option<String>

Content type

Defined in RFC7519#5.2.

jku: Option<String>

JSON Key URL

Defined in RFC7515#4.1.2.

jwk: Option<Jwk>

JSON Web Key

Defined in RFC7515#4.1.3.

kid: Option<String>

Key ID

Defined in RFC7515#4.1.4.

x5u: Option<String>

X.509 URL

Defined in RFC7515#4.1.5.

x5c: Option<Vec<String>>

X.509 certificate chain. A Vec of base64 encoded ASN.1 DER certificates.

Defined in RFC7515#4.1.6.

x5t: Option<String>

X.509 SHA1 certificate thumbprint

Defined in RFC7515#4.1.7.

x5t_s256: Option<String>

X.509 SHA256 certificate thumbprint

Defined in RFC7515#4.1.8.

This will be serialized/deserialized as “x5t#S256”, as defined by the RFC.

Implementations

impl Header

pub fn new(algorithm: Algorithm) -> Self

Returns a JWT header with the algorithm given

pub fn x5c_der(&self) -> Result<Option<Vec<Vec<u8>>>>

Decodes the X.509 certificate chain into ASN.1 DER format.

Trait Implementations

impl Clone for Header

fn clone(&self) -> Header

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Header

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

Formats the value using the given formatter.

impl Default for Header

fn default() -> Self

Returns a JWT header using the default Algorithm, HS256

impl<'de> Deserialize<'de> for Header

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>,
