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

ARGUMENTS         top

       gnutls_pubkey_t key

       gnutls_x509_crt_fmt_t format

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

       *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".
