Struct JwtCredentialValidatorHybrid

Source 
pub struct JwtCredentialValidatorHybrid<TRV, PQV>(/* private fields */);
Expand description

A type for decoding and validating Credentials signed with a PQ/T signature.

Implementations§

Source§

impl<TRV, PQV> JwtCredentialValidatorHybrid<TRV, PQV>
where TRV: JwsVerifier, PQV: JwsVerifier,

Source

pub fn with_signature_verifiers( traditional_signature_verifier: TRV, pq_signature_verifier: PQV, ) -> JwtCredentialValidatorHybrid<TRV, PQV>

Create a new JwtCredentialValidatorHybrid that delegates cryptographic signature verification to the given traditional JwsVerifier and PQ JwsVerifier.

Source

pub fn validate<DOC, T>( &self, credential_jwt: &Jwt, issuer: &DOC, options: &JwtCredentialValidationOptions, fail_fast: FailFast, ) -> Result<DecodedJwtCredential<T>, CompoundCredentialValidationError>
where T: Clone + Serialize + DeserializeOwned, DOC: AsRef<CoreDocument>,

Decodes and validates a Credential issued as a JWT. A DecodedJwtCredential is returned upon success.

The following properties are validated according to options:

  • the issuer’s PQ/T signature on the JWS,
  • the expiration date,
  • the issuance date,
  • the semantic structure.
§Warning

The lack of an error returned from this method is in of itself not enough to conclude that the credential 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 issuer’s DID Document

The caller must ensure that issuer represents an up-to-date DID Document.

§Properties that are not validated

There are many properties defined in The Verifiable Credentials Data Model that are not validated, such as: proof, credentialStatus, type, credentialSchema, refreshService and more. These should be manually checked after validation, according to your requirements.

§Errors

An error is returned whenever a validated condition is not satisfied.

Source

pub fn verify_signature<DOC, T>( &self, credential: &Jwt, trusted_issuers: &[DOC], options: &JwsVerificationOptions, ) -> Result<DecodedJwtCredential<T>, JwtValidationError>
where T: Clone + Serialize + DeserializeOwned, DOC: AsRef<CoreDocument>,

Decode and verify the PQ/T JWS signature of a Credential issued as a JWT using the DID Document of a trusted issuer.

A DecodedJwtCredential is returned upon success.

§Warning

The caller must ensure that the DID Documents of the trusted issuers are up-to-date.

§Proofs

Only the PQ/T JWS signature is verified. If the Credential contains a proof property this will not be verified by this method.

§Errors

This method immediately returns an error if the credential issuer’ url cannot be parsed to a DID belonging to one of the trusted issuers. Otherwise an attempt to verify the credential’s signature will be made and an error is returned upon failure.
