Struct jsonwebtoken::Validation

    pub required_spec_claims: HashSet<String>,

}

Contains the various validations that are applied after decoding a JWT.

All time validation happen on UTC timestamps as seconds.

use jsonwebtoken::{Validation, Algorithm};

let mut validation = Validation::new(Algorithm::HS256);
validation.leeway = 5;
// Setting audience
validation.set_audience(&["Me"]); // a single string
validation.set_audience(&["Me", "You"]); // array of strings
// or issuer
validation.set_issuer(&["Me"]); // a single string
validation.set_issuer(&["Me", "You"]); // array of strings

Fields

required_spec_claims: HashSet<String>

Which claims are required to be present before starting the validation. This does not interact with the various validate_*. If you remove exp from that list, you still need to set validate_exp to false. The only value that will be used are “exp”, “nbf”, “aud”, “iss”, “sub”. Anything else will be ignored.

Defaults to {"exp"}

leeway: u64

Add some leeway (in seconds) to the exp, iat and nbf validation to account for clock skew.

Defaults to 0.

validate_exp: bool

Whether to validate the exp field.

It will return an error if the time in the exp field is past.

Defaults to true.

validate_nbf: bool

Whether to validate the nbf field.

It will return an error if the current timestamp is before the time in the nbf field.

Defaults to false.

aud: Option<HashSet<String>>

If it contains a value, the validation will check that the aud field is a member of the audience provided and will error otherwise. Use set_audience to set it

Defaults to None.

iss: Option<HashSet<String>>

If it contains a value, the validation will check that the iss field is a member of the iss provided and will error otherwise. Use set_issuer to set it

Defaults to None.

sub: Option<String>

If it contains a value, the validation will check that the sub field is the same as the one provided and will error otherwise.

Defaults to None.

algorithms: Vec<Algorithm>

The validation will check that the alg of the header is contained in the ones provided and will error otherwise. Will error if it is empty.

Defaults to vec![Algorithm::HS256].

Implementations

impl Validation

pub fn new(alg: Algorithm) -> Validation

Create a default validation setup allowing the given alg

pub fn set_audience<T: ToString>(&mut self, items: &[T])

aud is a collection of one or more acceptable audience members The simple usage is set_audience(&["some aud name"])

pub fn set_issuer<T: ToString>(&mut self, items: &[T])

iss is a collection of one or more acceptable issuers members The simple usage is set_issuer(&["some iss name"])

pub fn set_required_spec_claims<T: ToString>(&mut self, items: &[T])

Which claims are required to be present for this JWT to be considered valid. The only values that will be considered are “exp”, “nbf”, “aud”, “iss”, “sub”. The simple usage is set_required_claims(&["exp", "nbf"]). If you want to have an empty set, do not use this function - set an empty set on the struct param directly.

pub fn insecure_disable_signature_validation(&mut self)

Whether to validate the JWT cryptographic signature Very insecure to turn that off, only do it if you know what you’re doing. With this flag turned off, you should not trust any of the values of the claims.

Trait Implementations

impl Clone for Validation

fn clone(&self) -> Validation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Validation

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

Formats the value using the given formatter.

impl Default for Validation

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq<Validation> for Validation

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
