gnutls_tpm_privkey_generate (gnutls_pk_algorithm_t pk,
                             unsigned int bits,
                             const char *srk_password,
                             const char *key_password,

                             unsigned int flags);

This function will generate a private key in the TPM chip. The private key will be generated within the chip and will be exported in a wrapped with TPM's master key form. Furthermore the wrapped key can be protected with the provided password .

Note that bits in TPM is quantized value. If the input value is not one of the allowed values, then it will be quantized to one of 512, 1024, 2048, 4096, 8192 and 16384.

Allowed flags are:

GNUTLS_TPM_KEY_SIGNING: Generate a signing key instead of a legacy,

GNUTLS_TPM_REGISTER_KEY: Register the generate key in TPM. In that case privkey would contain a URL with the UUID.

Since: 3.1.0

gnutls_tpm_key_list_deinit ()

void
gnutls_tpm_key_list_deinit (gnutls_tpm_key_list_t list);

This function will deinitialize the list of stored keys in the TPM.

Since: 3.1.0

gnutls_tpm_key_list_get_url ()

int
gnutls_tpm_key_list_get_url (gnutls_tpm_key_list_t list,
                             unsigned int idx,
                             char **url,
                             unsigned int flags);

This function will return for each given index a URL of the corresponding key. If the provided index is out of bounds then GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE is returned.

Since: 3.1.0

gnutls_tpm_get_registered ()

int
gnutls_tpm_get_registered (gnutls_tpm_key_list_t *list);

This function will get a list of stored keys in the TPM. The uuid of those keys

Since: 3.1.0

gnutls_tpm_privkey_delete ()

int
gnutls_tpm_privkey_delete (const char *url,
                           const char *srk_password);

This function will unregister the private key from the TPM chip.

Since: 3.1.0
