5.2.5 Using a PKCS #11 token with TLS

It is possible to use a PKCS #11 token to a TLS session, as shown in ex-pkcs11-client. In addition the following functions can be used to load PKCS #11 key and certificates by specifying a PKCS #11 URL instead of a filename.

int gnutls_certificate_set_x509_trust_file (gnutls_certificate_credentials_t cred, const char * cafile, gnutls_x509_crt_fmt_t type)

int gnutls_certificate_set_x509_key_file2 (gnutls_certificate_credentials_t res, const char * certfile, const char * keyfile, gnutls_x509_crt_fmt_t type, const char * pass, unsigned int flags)

Function: int gnutls_certificate_set_x509_system_trust (gnutls_certificate_credentials_t cred)

cred: is a gnutls_certificate_credentials_t structure.

This function adds the system’s default trusted CAs in order to verify client or server certificates.

In the case the system is currently unsupported GNUTLS_E_UNIMPLEMENTED_FEATURE is returned.

Returns: the number of certificates processed or a negative error code on error.
