updated crypto tools available

I submitted new versions of crash and psc mainly
to honor even more strict GCC behavior.
A lot of my own tools dont build anymore because of some
tricky type conversion which I always thought would be
plain ANSI. Well.
It seems to me that type conversion is not a possible
thing anymore today.
GCC folks told me to use memcpy() instead of *(int *)&buf[0] = 0x73;
Time to fix.
