Nagle) Organization: Stanford University Lines: 11 About five years ago, I posted to the net an "obvious password detector", a few pages of C intended for use in places such as "passwd" to detect an attempt to use a password that could be guessed by the usual techniques. (The algorithm worked by using the fact that the space of letter triples in English is only 20% populated.) If anyone still has this code, I would appreciate a copy; I no longer have one. John Nagle
