Eight-Character Password Limit in Mac OS X

Qwerpafw writes "While there have been the usual small announcements about Mac OS X security problems, there has been nothing so major as to make me worry about the security of my own box. However, I recently learned that for some reason, Mac OS X only understands passwords of up to 8 characters. Any other characters typed in are discarded as 'garbage.' Well, this worried me, as 8 characters is generally regarded as a rather small keysize, with only 256^8 maximum possibilities (or about 1.845 * 10^19). This is a very real hole in Mac OS X. To make things worse, I was able to find no mention of this at Apple's website, and you are never alerted of this when trying to enter password greater than eight characters." This is generally not regarded a security "hole", and has existed in BSD for many years (though most current BSDs have moved beyond the limitation). It is something to be aware of, and it would be nice if there were a workaround ...

    Hrmm, I guess at least they're buying Macs. Market share numbers don't differentiate between emo fucks, Slashdot trolls, or CowboyNeal.

    Oh, and have I mentioned I love your work? No? Well, I just did. Here and MacSlash. Keep it up! You know what I'm talking about ;)

    I think it's Appletalk related. In OS 9 an appletalk password can only be 8 characters long....

    Which means this is news only because Apple does it, too?

    Slashdot must be starving for hit counts today.
