 * WARNING WARNING WARNING WARNING WARNING WARNING WARNING WARNING
 *
 * The function names in here are deprecated and are only present to
 * provide an interface compatible with openssl 0.9.6 and older as
 * well as libdes.  OpenSSL now provides functions where "des_" has
 * been replaced with "DES_" in the names, to make it possible to
 * make incompatible changes that are needed for C type security and
 * other stuff.
 *
 * This include files has two compatibility modes:
 *
 *   - If OPENSSL_DES_LIBDES_COMPATIBILITY is defined, you get an API
 *     that is compatible with libdes and SSLeay.
 *   - If OPENSSL_DES_LIBDES_COMPATIBILITY isn't defined, you get an
 *     API that is compatible with OpenSSL 0.9.5x to 0.9.6x.
 *
 * Note that these modes break earlier snapshots of OpenSSL, where
 * libdes compatibility was the only available mode or (later on) the
 * prefered compatibility mode.  However, after much consideration
 * (and more or less violent discussions with external parties), it
 * was concluded that OpenSSL should be compatible with earlier versions
 * of itself before anything else.  Also, in all honesty, libdes is
 * an old beast that shouldn't really be used any more.
 *
 * Please consider starting to use the DES_ functions rather than the
 * des_ ones.  The des_ functions will disappear completely before
 * OpenSSL 1.0!
