gnutls_verify_stored_pubkey - API function
#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);
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.
