Expand description

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 and nbf validation to account for clock skew.

Defaults to 60.

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

Create a default validation setup allowing the given alg

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

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

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_spec_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.

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.
