Folks,

I need to check when a password is created that it does not belong to any word in a dictionary. How can I do this? Any ideas?

If I have to use database, how can I load the dictionary into database.

I need to do this for english and french.

Thanks in advance.

The simplest and fastest lookup would be using an in-memory java.util.HashSet created from a word list. Once created you can serialize the HashSet to a disk file and read it when needed. In my phonetic lookup experiments I found that a HashMap of 60,000 common words plus phonetic codes takes only 871KB when serialized to a file.

Do a google search for "moby words" to find sources for word lists.
