   5  *
   6  * The function names in here are deprecated and are only present to
   7  * provide an interface compatible with openssl 0.9.6 and older as
   8  * well as libdes.  OpenSSL now provides functions where "des_" has
   9  * been replaced with "DES_" in the names, to make it possible to
  10  * make incompatible changes that are needed for C type security and
  11  * other stuff.
  12  *
  13  * This include files has two compatibility modes:
  14  *
  15  *   - If OPENSSL_DES_LIBDES_COMPATIBILITY is defined, you get an API
  16  *     that is compatible with libdes and SSLeay.
  17  *   - If OPENSSL_DES_LIBDES_COMPATIBILITY isn't defined, you get an
  18  *     API that is compatible with OpenSSL 0.9.5x to 0.9.6x.
  19  *
  20  * Note that these modes break earlier snapshots of OpenSSL, where
  21  * libdes compatibility was the only available mode or (later on) the
  22  * prefered compatibility mode.  However, after much consideration
  23  * (and more or less violent discussions with external parties), it
  24  * was concluded that OpenSSL should be compatible with earlier versions
  25  * of itself before anything else.  Also, in all honesty, libdes is
  26  * an old beast that shouldn't really be used any more.
  27  *
  28  * Please consider starting to use the DES_ functions rather than the
  29  * des_ ones.  The des_ functions will disappear completely before
  30  * OpenSSL 1.0!
