gnutls_tpm_privkey_generate — API function

Synopsis

#include <gnutls/tpm.h>

int gnutls_tpm_privkey_generate(gnutls_pk_algorithm_t pk, unsigned int bits, const char * srk_password, const char * key_password, gnutls_tpmkey_fmt_t format, gnutls_x509_crt_fmt_t pub_format, gnutls_datum_t * privkey, gnutls_datum_t * pubkey, unsigned int flags);

Arguments

gnutls_pk_algorithm_t pk
the public key algorithm
unsigned int bits
the security bits
const char * srk_password
a password to protect the exported key (optional)
const char * key_password
the password for the TPM (optional)
gnutls_tpmkey_fmt_t format
the format of the private key
gnutls_x509_crt_fmt_t pub_format
the format of the public key
gnutls_datum_t * privkey
the generated key
gnutls_datum_t * pubkey
the corresponding public key (may be null)
unsigned int flags
should be a list of GNUTLS_TPM_* flags

Description

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:

Returns

On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.
