"Anonymous'" comment of Nov 19th refers to an encryption scheme known as a
'one-time pad'. Anonymous forgot to mention that, while it's true the one-time pad is
secure as long as the key's kept secret, it's also necessary to avoid reusing keys --
multiple plaintexts encrypted using a single key are insecure, too, because of collisions, and
that's why it's called a 'one-time pad'. Hope this helps --
