gnutls_verify_stored_pubkey — API function


#include <gnutls/gnutls.h>
int gnutls_verify_stored_pubkey( const char * db_name,
  gnutls_tdb_t tdb,
  const char * host,
  const char * service,
  gnutls_certificate_type_t cert_type,
  const gnutls_datum_t * cert,
  unsigned int flags);


const char * db_name

A file specifying the stored keys (use NULL for the default)

gnutls_tdb_t tdb

A storage structure or NULL to use the default

const char * host

The peer's name

const char * service

non−NULL if this key is specific to a service (e.g. http)

gnutls_certificate_type_t cert_type

The type of the certificate

const gnutls_datum_t * cert

The raw (der) data of the certificate

unsigned int flags

should be 0.


This function will try to verify the provided certificate using a list of stored public keys. The service field if non−NULL should be a port number.

The 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 GNUTLS_E_CERTIFICATE_KEY_MISMATCH if the host/service pair is found but key doesn't match, 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.


If no associated public key is found then GNUTLS_E_NO_CERTIFICATE_FOUND will be returned. If a key is found but does not match GNUTLS_E_CERTIFICATE_KEY_MISMATCH is returned. On success, GNUTLS_E_SUCCESS (0) is returned, or a negative error value on other errors.
