Expand description

Struct for validating Presentation.

Implementations§

Source§

impl<V> JwtPresentationValidator<V>
where V: JwsVerifier,

Source

pub fn with_signature_verifier( signature_verifier: V, ) -> JwtPresentationValidator<V>

Creates a new JwtPresentationValidator using a specific JwsVerifier.

Source

pub fn validate<HDOC, CRED, T>( &self, presentation: &Jwt, holder: &HDOC, options: &JwtPresentationValidationOptions, ) -> Result<DecodedJwtPresentation<CRED, T>, CompoundJwtPresentationValidationError>
where HDOC: AsRef<CoreDocument> + ?Sized, T: ToOwned<Owned = T> + Serialize + DeserializeOwned, CRED: ToOwned<Owned = CRED> + Serialize + DeserializeOwned + Clone,

Validates a Presentation.

The following properties are validated according to options:

  • the JWT can be decoded into a semantically valid presentation.
  • the expiration and issuance date contained in the JWT claims.
  • the holder’s signature.

Validation is done with respect to the properties set in options.

§Warning
  • This method does NOT validate the constituent credentials and therefore also not the relationship between the credentials’ subjects and the presentation holder. This can be done with JwtCredentialValidationOptions.
  • The lack of an error returned from this method is in of itself not enough to conclude that the presentation can be trusted. This section contains more information on additional checks that should be carried out before and after calling this method.
§The state of the supplied DID Documents.

The caller must ensure that the DID Documents in holder and issuers are up-to-date.

§Errors

An error is returned whenever a validated condition is not satisfied or when decoding fails.
