World record in password checking
[forwarded for your enjoyment --eric]
A NEW WORLD RECORD IN PASSWORD CHECKING HAS BEEN SET:
-----------------------------------------------------
Roch Bourbonnais, a Thinking Machines Corporation engineer, has ported
and optimized the CM/2 port of the UFC-crypt to a CM/5 system.
The UFC-crypt (Ultra Fast Crypt) implementation on the CM/2 Connection
Machine (parallel computer) is a UNIX password checking routine (crypt())
ported by Michael Glad at UNI-C.
The port, that is written in CM-fortran, utilizes the CM/5 vector units
and is partly programmed in cdpeac (vector unit assembly language).
The package achieves 1560 encryptions/second/vector unit. This scales to
6,4 million encryptions per second on a large 1024 node machine.
800,000 - - - - - small 128 - -
With this impressive performance, all combinations of 6 letters can be
tried in less than an hour and all combinations of 6 lower-case letters
can be tried in less than one minute.
Congratulations,
Jorgen Bo Madsen
