This functions is the same as DES_encrypt1() except that the DES
initial permutation (IP) and final permutation (FP) have been left
out. As for DES_encrypt1(), you should not use this function.
It is used by the routines in the library that implement triple DES.
IP() DES_encrypt2() DES_encrypt2() DES_encrypt2() FP() is the same
as DES_encrypt1() DES_encrypt1() DES_encrypt1() except faster :-\).
