gnutls_tpm_privkey_generate - API function


#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);


the public key algorithm
the security bits
a password to protect the exported key (optional)
the password for the TPM (optional)
the format of the private key
the format of the public key
the generated key
the corresponding public key (may be null)
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.
