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!
