- This bit of code was derived from the UFC-crypt package which
- carries the following copyright
-
- Modified for use by Samba by Andrew Tridgell, October 1994
-
- Note that this routine is only faster on some machines. Under Linux 1.1.51
- libc 4.5.26 I actually found this routine to be slightly slower.
-
- Under SunOS I found a huge speedup by using these routines
- (a factor of 20 or so)
-
- Warning: I've had a report from Steve Kennedy <steve@gbnet.org>
- that this crypt routine may sometimes get the wrong answer. Only
- use UFC_CRYT if you really need it.
