How about pass in the `KeyIdentifier` instead of `PublicKey akey` into the createV3Extensions method? And you can calculated with
        X509CertImpl impl;
        if (signerCert instanceof X509CertImpl) {
            impl = (X509CertImpl) signerCert;
        } else {
            impl = new X509CertImpl(signerCert.getEncoded());
        }
        impl.getSubjectKeyId();
