Overview
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.
