What legal reasons prevent this software vendor from including encryption in their code?
<p>I am working on a software project that requires the use of a setup program. The one my company is using is InnoSetup.</p>
<p>On their <a href="https://jrsoftware.org/isdl.php" rel="nofollow noreferrer">downloads page</a> towards the bottom, under the section titled <strong>Encryption Module</strong> it says:</p>
<blockquote>
<p>&quot;For legal reasons, encryption code is not built into Inno Setup. You must download a separate &quot;encryption module&quot; if you wish to utilize Inno Setup's encryption capabilities...&quot;</p>
</blockquote>
<p>What legal reasons are they referring to?</p>

<p>It may be an anachronism, see <a href="https://en.wikipedia.org/wiki/Export_of_cryptography_from_the_United_States" rel="nofollow">https://en.wikipedia.org/wiki/Export_of_cryptography_from_the_United_States</a></p>
