> There's an endless loop when checking the certificate of an OCSP response with a specific TSA. Solution: {{CertificateVerifier.verifyOCSP}} must make sure when checking the certificate of the responder that this isn't the certificate it is checking right now.
> There's also a recursion in {{AddValidationInformation.addOcspData()}} which then calls {{updateVRI()}}, which ends up checking the certificate again later, so I'll use a set to prevent that to happen.
