NAME

       gnutls_verify_stored_pubkey - API function

SYNOPSIS

       #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);

ARGUMENTS

       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.

DESCRIPTION

       This function will try to verify a raw public-key or  a  public-key  provided  via  a  raw  (DER-encoded)
       certificate using a list of stored public keys.  The  service field if non-NULL should be a port number.

       The   db_name 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.

       As of GnuTLS 3.6.6 this function also verifies raw public keys.

RETURNS

       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.

SINCE

       3.0.13
