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

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:

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