NAME
gnutls_x509_privkey_export_pkcs8 - This function will export the private key to PKCS8 format
SYNOPSIS
#include <gnutls/x509.h>
I int gnutls_x509_privkey_export_pkcs8(gnutls_x509_privkey_t key , gnutls_x509_crt_fmt_t format , const char * password , unsigned int flags , void * output_data , size_t * output_data_size );
ARGUMENTS
"gnutls_x509_privkey_t
Holds the key
"gnutls_x509_crt_fmt_t
the format of output params. One of PEM or DER.
"const
the password that will be used to encrypt the key.
"unsigned
an ORed sequence of gnutls_pkcs_encrypt_flags_t
"void
will contain a private key PEM or DER encoded
"size_t
holds the size of output_data (and will be
replaced by the actual size of parameters)
DESCRIPTION
This function will export the private key to a PKCS8 structure.
Currently only RSA keys can be exported since there is no documented
standard for other keys. 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.
RETURN VALUE
In case of failure a negative value will be
returned, and 0 on success.
