@deftypefun {int} {gnutls_verify_stored_pubkey} (const char * @var{db_name}, gnutls_tdb_t @var{tdb}, const char * @var{host}, const char * @var{service}, gnutls_certificate_type_t @var{cert_type}, const gnutls_datum_t * @var{cert}, unsigned int @var{flags})
@var{db_name}: A file specifying the stored keys (use NULL for the default)
@var{tdb}: A storage structure or NULL to use the default
@var{host}: The peer's name
@var{service}: non-NULL if this key is specific to a service (e.g. http)
@var{cert_type}: The type of the certificate
@var{cert}: The raw (der) data of the certificate
@var{flags}: should be 0.
This function will try to verify the provided (raw or DER-encoded) certificate
using a list of stored public keys. The @code{service} field if non-NULL should
be a port number.
The @code{retrieve} variable if non-null specifies a custom backend for
the retrieval of entries. If it is NULL then the
default file backend will be used. In POSIX-like systems the
file backend uses the $HOME/.gnutls/known_hosts file.
Note that if the custom storage backend is provided the
retrieval function should return @code{GNUTLS_E_CERTIFICATE_KEY_MISMATCH}
if the host/service pair is found but key doesn't match,
@code{GNUTLS_E_NO_CERTIFICATE_FOUND} if no such host/service with
the given key is found, and 0 if it was found. The storage
function should return 0 on success.
@strong{Returns:} If no associated public key is found
then @code{GNUTLS_E_NO_CERTIFICATE_FOUND} will be returned. If a key
is found but does not match @code{GNUTLS_E_CERTIFICATE_KEY_MISMATCH}
is returned. On success, @code{GNUTLS_E_SUCCESS} (0) is returned,
or a negative error value on other errors.
@strong{Since:} 3.0.13
