gnutls_verify_stored_pubkey - API function
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);
- 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.
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.
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.
