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 the provided (raw or DER-encoded) 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.

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.
