15 # DES_PTR use pointer lookup vs arrays in the DES in crypto/des/des_locl.h
16 # DES_RISC1 use different DES_ENCRYPT macro that helps reduce register
17 # dependancies but needs to more registers, good for RISC CPU's
18 # DES_RISC2 A different RISC variant.
19 # DES_UNROLL unroll the inner DES loop, sometimes helps, somtimes hinders.
20 # DES_INT use 'int' instead of 'long' for DES_LONG in crypto/des/des.h
21 # This is used on the DEC Alpha where long is 8 bytes

31 # RC4_LONG use 'long' instead of 'int' for RC4_INT in crypto/rc4/rc4.h
32 # RC4_INDEX define RC4_INDEX in crypto/rc4/rc4_enc.c. This turns on
