| 5 | * The function names in here are deprecated and are only present to |
| 6 | * provide an interface compatible with libdes. OpenSSL now provides |
| 7 | * functions where "des_" has been replaced with "DES_" in the names, |
| 8 | * to make it possible to make incompatible changes that are needed |
| 9 | * for C type security and other stuff. |
| 10 | * |
| 11 | * Please consider starting to use the DES_ functions rather than the |
| 12 | * des_ ones. The des_ functions will dissapear completely before |
| 13 | * OpenSSL 1.0! |
