Currently in the protocol file (https://github.com/ntop/nDPI/blob/dev/example/protos.txt) it is not possible to binda protocol to a TLS certificate.

In https://github.com/ntop/nDPI/blob/dev/src/lib/ndpi_content_match.c.inc protocols are defined as follows:

static ndpi_tls_cert_name_match tls_certificate_match [] = {
  { "CN=AnyDesk Client",               NDPI_PROTOCOL_ANYDESK     },
  { "O=philandro Software GmbH",       NDPI_PROTOCOL_ANYDESK     },
...
}

This is to request to extend protocols file wi enable the creation of new protocols based on the certificate name (i.e. allow definition of new protocols other than using tls_certificate_match)
