.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 PKCS\fB1\fP structure for
RSA or RSA\-PSS keys, and integer sequence for DSA keys. Other keys types
will be exported in PKCS\fB8\fP form.

If the structure is PEM encoded, it will have a header
of "BEGIN RSA PRIVATE KEY".

It is recommended to use \fBgnutls_x509_privkey_export_pkcs8()\fP instead
of this function, when a consistent output format is required.
.SH "RETURNS"
On success, \fBGNUTLS_E_SUCCESS\fP (0) is returned, otherwise a
negative error value.
