6 | * The function names in here are deprecated and are only present to | |
7 | * provide an interface compatible with libdes. OpenSSL now provides | |
8 | * functions where "des_" has been replaced with "DES_" in the names, | |
9 | * to make it possible to make incompatible changes that are needed | |
10 | * for C type security and other stuff. | |
11 | * | |
12 | * Please consider starting to use the DES_ functions rather than the | |
13 | * des_ ones. The des_ functions will dissapear completely before | |
14 | * OpenSSL 1.0! | |
