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
