       ne_ssl_cert_read, ne_ssl_cert_write, ne_ssl_cert_import,
       ne_ssl_cert_export - functions to read or write certificates to and
       from files or strings


       #include <ne_ssl.h>

       ne_ssl_certificate *ne_ssl_cert_read(const char *filename);

       int ne_ssl_cert_write(const ne_ssl_certificate *cert,
                             const char *filename);

       ne_ssl_certificate *ne_ssl_cert_import(const char *data);

       char *ne_ssl_cert_export(const ne_ssl_certificate *cert);


       The ne_ssl_cert_write function writes a certificate to a file using the
       PEM encoding. The ne_ssl_cert_export function returns a base64-encoded
       NUL-terminated string representing the certificate. This string is
       malloc-allocated and should be destroyed using free by the caller.

       The ne_ssl_cert_read function reads a certificate from a PEM-encoded
       file, and returns a certificate object. The ne_ssl_cert_import function
       returns a certificate object from a base64-encoded string, data, as
       returned by ne_ssl_cert_export. The certificate object returned by
       these functions should be destroyed using ne_ssl_cert_free after use.


       ne_ssl_cert_read returns NULL if a certificate could not be read from
       the file.  ne_ssl_cert_write returns non-zero if the certificate could
       not be written to the file.  ne_ssl_cert_export always returns a
       NUL-terminated string, and never NULL.  ne_ssl_cert_import returns NULL
       if the string was not a valid base64-encoded certificate.


       The string produced by ne_ssl_cert_export is the base64 encoding of the
       DER representation of the certificate. The file written by
       ne_ssl_cert_write uses the PEM format: this is the base64 encoding of
       the DER representation with newlines every 64 characters, and start and
       end marker lines.
