NAME
       gnutls_pubkey_export - API function

SYNOPSIS
       #include <gnutls/abstract.h>

       int gnutls_pubkey_export(gnutls_pubkey_t key, gnutls_x509_crt_fmt_t
       format, void * output_data, size_t * output_data_size);

ARGUMENTS
       gnutls_pubkey_t key
                   Holds the certificate

       gnutls_x509_crt_fmt_t format
                   the format of output params. One of PEM or DER.

       void * output_data
                   will contain a certificate PEM or DER encoded

       size_t * output_data_size
                   holds the size of output_data (and will be replaced by the
                   actual size of parameters)

DESCRIPTION
       This function will export the public key to DER or PEM format.  The
       contents of the exported data is the SubjectPublicKeyInfo X.509
       structure.

       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
       CERTIFICATE".

RETURNS
       In case of failure a negative error code will be returned, and 0 on
       success.
