I thought that the SecureID algorithm had become known (Ok...
That's not the same thing as "being published"). Was my understanding,
from the same source that I got my SecureID app for my palm pilot, that
the same process that had led to that application being available on the
Palm Pilot had resulted in the algorithm being known.
That being said, I don't have a copy of the algorithm, and it was
not claimed that it was "published" by the SecureID people. But I do have
the SecureID calculator on my palm pilot. It's there in 68K binary, so it
could be reverse engineered. I have not installed the "SecureID key
file" (the Network Administrator here is throughly PISSED that I, of all
people, have the ability to use SecureID without one of his precious
dongles and has not given me a key file, yet.) so it's just running in
"demo" mode. (Besides, I've got a lot more systems where I use S/Key
than SecureID, and now I've got S/Key integrated into the new version
of Strip on the Palm Pilot - I really don't need SecureID.)
BTW... We have had abysmal luck with the SecureID keyfobs. I've
never even used mine and I looked at it one day and the LCD was gibberish.
I asked said Admin if I needed to stroke the tomaguci more often to keep
it happy. He failed to see the humor. That's WHY I want the key file to
activate my SecureID calculator on my Palm Pilot. That's also WHY he's
so pissy about it. He hates to feel like he had to give in because the
damn things are unreliable. Another individual has gone through a
half a dozen in the last year. I'm not impressed... But they keep
buying more of them.
