NAME

6       gnutls_verify_stored_pubkey - API function
7

SYNOPSIS

9       #include <gnutls/gnutls.h>
10
11       int gnutls_verify_stored_pubkey(const char * db_name, gnutls_tdb_t tdb,
12       const char * host,  const  char  *  service,  gnutls_certificate_type_t
13       cert_type, const gnutls_datum_t * cert, unsigned int flags);
14

ARGUMENTS

16       const char * db_name
17                   A  file  specifying  the  stored  keys  (use  NULL  for the
18                   default)
19
20       gnutls_tdb_t tdb
21                   A storage structure or NULL to use the default
22
23       const char * host
24                   The peer's name
25
26       const char * service
27                   non-NULL if this key is specific to a service (e.g. http)
28
29       gnutls_certificate_type_t cert_type
30                   The type of the certificate
31
32       const gnutls_datum_t * cert
33                   The raw (der) data of the certificate
34
35       unsigned int flags
36                   should be 0.
37

DESCRIPTION

39       This function will try to verify a raw public-key or a public-key  pro‐
40       vided via a raw (DER-encoded) certificate using a list of stored public
41       keys.  The  service field if non-NULL should be a port number.
42
43       The  db_name variable if non-null specifies a custom  backend  for  the
44       retrieval  of entries. If it is NULL then the default file backend will
45       be  used.  In  POSIX-like   systems   the   file   backend   uses   the
46       $HOME/.gnutls/known_hosts file.
47
48       Note that if the custom storage backend is provided the retrieval func‐
49       tion should return GNUTLS_E_CERTIFICATE_KEY_MISMATCH if  the  host/ser‐
50       vice pair is found but key doesn't match, GNUTLS_E_NO_CERTIFICATE_FOUND
51       if no such host/service with the given key is found, and 0  if  it  was
52       found. The storage function should return 0 on success.
53
54       As of GnuTLS 3.6.6 this function also verifies raw public keys.
55

RETURNS

57       If no associated public key is found then GNUTLS_E_NO_CERTIFICATE_FOUND
58       will be returned. If a key is found but does  not  match  GNUTLS_E_CER‐
59       TIFICATE_KEY_MISMATCH  is returned. On success, GNUTLS_E_SUCCESS (0) is
60       returned, or a negative error value on other errors.
