What's wrong with just testing whether it's < 128 ?


So if I create a new account with the password "1234567890ABCDEF", the
database will be updated to say that my password is "1234567890AB", but
the website never mentions that truncation has occured. Then when I try
to log on with the password "1234567890ABCDEF", it compares
"1234567890ABCDEF" (what I wrote) against "1234567890AB" (what's in the
DB), sees that they are not equal, and tell me that my password is
incorrect.

I think it was Sun who (inspired to a display of the very highest technical
standards), mapped my user-id and password to lower case before entering them
into the database, but didn't perform the same mapping when checking them
later...
