<h2>Secret talk with a computer</h2>
<p>in this document I will show you how to talk with the computer like a <a href="https://mango.pdf.zone/">real hacker</a>!</p>
<h3>A secret message</h3>
<p>Inside this document is hidden a super secret message, the only way to see it
(other than checking the source)
is forcing the computer to spit out and confess:</p>
<pre><code class="nim">echo secret</code></pre>
<pre>[104, 101, 108, 108, 111, 44, 32, 119, 111, 114, 108, 100]</pre>
<p>what does the computer want to say? It is almost impossible to say,
it looks like a completely random integer sequence
(yeah, <a href="https://oeis.org/search?q=104%2C+101%2C+108%2C+108%2C+111%2C+44%2C+32%2C+119%2C+111%2C+114%2C+108%2C+100&language=english&go=Search">well</a>).</p>
<h3>A cryptoanalytic weapon</h3>
<p>I actually happen to have one of the most powerful crypto-cracking device, a nim <code>func</code>,
that will allow us to decipher this enigmatic message. Here it is:</p>
<pre><code class="nim">func decode(secret: openArray[int]): string =
  ## classified by NSA as <a href="https://www.nsa.gov/Portals/70/documents/news-features/declassified-documents/cryptologic-histories/EC-121.pdf">TOP SECRET</a>
  for c in secret:
    result.add char(c)</code></pre>
<h3>The great revelation</h3>
<p>Although the algorithm is too complicated for me to understand,
I can just apply it to my secret message and
finally decrypt what the computer wants to tell me:</p>
<pre><code class="nim">let msg = decode secret
echo msg</code></pre>
<pre>hello, world</pre>
<p><em>Hey</em>, there must be a bug somewhere, the message (<code>hello, world</code>) is not even addressed to me!</p>
