NAME

       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

SYNOPSIS

       #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);

DESCRIPTION

       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.

RETURN VALUE

       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.

ENCODING FORMATS

       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.
