### Security
Parsedown is capable of escaping user-input within the HTML that it generates.
Additionally Parsedown will apply sanitisation to additional scripting vectors (such
as scripting link destinations) that are introduced by the markdown syntax itself.
Parsedown is capable of escaping user-input within the HTML that it generates. Additionally Parsedown will apply sanitisation to additional scripting vectors (such as scripting link destinations) that are introduced by the markdown syntax itself.
To tell Parsedown that it is processing untrusted user-input, use the following:
```php
$parsedown = new Parsedown;
$parsedown->setSafeMode(true);
```
If instead, you wish to allow HTML within untrusted user-input, but still want
output to be free from XSS it is recommended that you make use of a HTML sanitiser
that allows HTML tags to be whitelisted, like [HTML Purifier](http://htmlpurifier.org/).

In both cases you should strongly consider employing defence-in-depth measures,
like [deploying a Content-Secuity-Policy](https://scotthelme.co.uk/content-security-policy-an-introduction/)
(making use of browser security feature) so that your page is likely to be safe even if an
attacker finds a vulnerability in one of the first lines of defence above.
