.SH NAME
gnutls_x509_privkey_export \- API function
.SH SYNOPSIS
.B #include <gnutls/x509.h>
.sp
.BI "int gnutls_x509_privkey_export(gnutls_x509_privkey_t " key ", gnutls_x509_crt_fmt_t " format ", void * " output_data ", size_t * " output_data_size ");"
.SH ARGUMENTS
.IP "gnutls_x509_privkey_t key" 12
Holds the key
.IP "gnutls_x509_crt_fmt_t format" 12
the format of output params. One of PEM or DER.
.IP "void * output_data" 12
will contain a private key PEM or DER encoded
.IP "size_t * output_data_size" 12
holds the size of output_data (and will be
replaced by the actual size of parameters)
.SH "DESCRIPTION"
This function will export the private key to a PKCS1 structure for
RSA keys, or an integer sequence for DSA keys.  The DSA keys are in
the same format with the parameters used by openssl.

If the buffer provided is not long enough to hold the output, then
* \fIoutput_data_size\fP is updated and \fBGNUTLS_E_SHORT_MEMORY_BUFFER\fP
will be returned.

If the structure is PEM encoded, it will have a header
of "BEGIN RSA PRIVATE KEY".
.SH "RETURNS"
On success, \fBGNUTLS_E_SUCCESS\fP (0) is returned, otherwise a
negative error value.
.SH "REPORTING BUGS"
