Subject: Re: Using Ruby Hash for Crytography?

Hi David,

Probably the problem is not that bad.  A hash value can be populated with
the default value only when the hash[key] is called as an rvalue.  As an
(imaginary) example:

    hsh = Hash.new ('a')
    puts hsh['x']  # >> 'a'
    puts hsh['y']  # >> 'a'
    hsh.keys       # ->  ['x', 'y']

Regards,

Bill
