    14     14   
           15  +<p>The scheme is that message M_n signature is a secure hash of a concatenation
           16  +of all messages since the first message, message M_n included. If M_1 is a file
           17  +with the very first message that the signer sent and M_2 is the 2. message that
           18  +the signer sent, then a way to calculate the signature is:</p>
           19  +<pre>    cat ./M_1.blob  &gt; ./x.blob   # The "&gt;" is required for overwriting the old x.blob .</pre>
           20  +<pre>    cat ./M_2.blob &gt;&gt; ./x.blob   # The "&gt;&gt;" in stead of the "&gt;" is </pre>
           21  +<pre>                                 # required to add in stead of overwriting.</pre>
           22  +<pre>    cat ./M_3.blob &gt;&gt; ./x.blob</pre>
           23  +<pre>    ...</pre>
           24  +<pre>    cat ./M_n.blob &gt;&gt; ./x.blob</pre>

           30  +<p>The secure hash is stored to a text file that is separate from the M_n.&nbsp;</p>
