ARGUMENTS        top

       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        top

       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 providedpassword .       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        top

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