61 * The function names in here are deprecated and are only present to
62 * provide an interface compatible with libdes. OpenSSL now provides
63 * functions where "des_" has been replaced with "DES_" in the names,
64 * to make it possible to make incompatible changes that are needed
65 * for C type security and other stuff.
67 * Please consider starting to use the DES_ functions rather than the
68 * des_ ones. The des_ functions will dissapear completely before
