NAME         top

       gnutls_verify_stored_pubkey - API function

SYNOPSIS         top

       #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         top

       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         top

       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         top

       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.
