v0.28.0

What's Changed

• Add support for issuer metadata policy and update OpenID4VP dependency to v0.33.0 by @phisakel in #343

Configure Issuer Metadata Policy

When you need strict validation of issuer metadata signatures using certificate chains (such as IACA root certificates), you can configure the issuer's OpenId4VciConfiguration with a signed metadata policy:

// Create a certificate chain trust validator with IACA root certificates
let trust: CertificateChainTrust = TrustedChainValidator(iacaRoots: [eudic])

// Create an issuer metadata policy that requires signed metadata
let issuerMetadataPolicy: IssuerMetadataPolicy = .requireSigned(issuerTrust: .byCertificateChain(certificateChainTrust: trust))

// Configure the issuer with the strict signed metadata policy
let config = OpenId4VciConfiguration(credentialIssuerURL: "https://issuer.example.com", clientId: "my-wallet",
 issuerMetadataPolicy: issuerMetadataPolicy)
