well i'm not very good at ruby, but i was thinking of something like
-------------------------------------------------------------------
#!/usr/bin/ruby

def generatePassword(minlen = 5, maxlen = 10)

  passwd_len = (rand(maxlen - minlen) + minlen)
  passwd = ""

  while (passwd.length < passwd_len) do
    n = rand(74) + 48;
    passwd << n.chr if (n < 58 || n > 64 && n < 91 || n > 96)
  end

  password

end

puts generatePassword()
-----------------------------------------------
is there a more straight-forward way of doing it?

love,
pizza
