Enum Verifier

#[non_exhaustive]
pub enum Verifier<'a> {
    VerifyTrustPolicy(&'a CertificateTrustPolicy),
    VerifyCertificateProfileOnly(&'a CertificateTrustPolicy),
    IgnoreProfileAndTrustPolicy,
}

A Verifier reads a COSE signature and reports on its validity.

It can provide different levels of verification depending on the enum value chosen.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

VerifyTrustPolicy(&'a CertificateTrustPolicy)

Use a CertificateTrustPolicy to validate the signing certificate’s profile against C2PA requirements and validate the certificate’s membership against a trust configuration.

VerifyCertificateProfileOnly(&'a CertificateTrustPolicy)

Validate the certificate’s membership against a trust configuration, but do not against any trust list. The CertificateTrustPolicy is used to enforce EKU (Extended Key Usage) policy only.

IgnoreProfileAndTrustPolicy

Ignore both trust configuration and trust lists.

Implementations

impl Verifier<'_>

pub fn verify_signature( &self, cose_sign1: &[u8], data: &[u8], additional_data: &[u8], validation_log: &mut impl StatusTracker, ) -> Result<CertificateInfo, CoseError>

Verify a COSE signature according to the configured policies.

pub async fn verify_signature_async( &self, cose_sign1: &[u8], data: &[u8], additional_data: &[u8], validation_log: &mut impl StatusTracker, ) -> Result<CertificateInfo, CoseError>

Verify a COSE signature according to the configured policies.
