Indeed but I'm thinking that someone might do more than check a single
issuer. He might want to print the whole imported list. In that case
I'd use something like gnutls_certificate_export_x509_cas() that will
return the whole list of issuers, and your check can be done at the
application level. Would something like this suit you?
