     [auth-rsa.c channels.c jpake.c key.c misc.c misc.h monitor.c]
     [packet.c ssh-rsa.c]
     implement a timing_safe_cmp() function to compare memory without leaking
     timing information by short-circuiting like memcmp() and use it for
     some of the more sensitive comparisons (though nothing high-value was
     readily attackable anyway); "looks ok" markus@
