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
