an ORed sequence of gnutls_pkcs_encrypt_flags_t

holds the size of output_data (and will be replaced by the actual size of parameters)
This function will export the private key to a PKCS8
structure. Both RSA and DSA keys can be exported. For DSA
keys we use PKCS 11
definitions. If the flags do not specify the encryption
cipher, then the default 3DES (PBES2) will be used.
The password can
be either ASCII or UTF−8 in the default PBES2
encryption schemas, or ASCII for the PKCS12 schemas.
If the buffer provided is not long enough to hold the output, then *output_data_size is updated and GNUTLS_E_SHORT_MEMORY_BUFFER will be returned.
If the structure is PEM encoded, it will have a header of "BEGIN ENCRYPTED PRIVATE KEY" or "BEGIN PRIVATE KEY" if encryption is not used.
