unsigned int port
The port of the service connecting (e.g. 443)
unsigned int sflags

Описание (Description)
This function will verify the given certificate chain against the
CA constrains and/or the certificate available via DANE. If no
information via DANE can be obtained the flag
DANE_VERIFY_NO_DANE_INFO
is set. If a DNSSEC signature is not
available for the DANE record then the verify flag
DANE_VERIFY_NO_DNSSEC_DATA
is set.
Due to the many possible options of DANE, there is no single
threat model countered. When notifying the user about DANE
verification results it may be better to mention: DANE
verification did not reject the certificate, rather than
mentioning a successful DANE verication.
Note that this function is designed to be run in addition to PKIX
- certificate chain - verification. To be run independently the
DANE_VFLAG_ONLY_CHECK_EE_USAGE
flag should be specified; then the
function will check whether the key of the peer matches the key
advertized in the DANE entry.
Возвращаемое значение (Return value)
a negative error code on error and DANE_E_SUCCESS
(0) when the
DANE entries were successfully parsed, irrespective of whether
they were verified (see verify for that information). If no
usable entries were encountered
DANE_E_REQUESTED_DATA_NOT_AVAILABLE
will be returned.
