# PDF file password protection

This feature allows adding parameter to the query's url, in it's value we put password with which we want to encrypt the pdf file.

{% hint style="info" %}
if tool/method we use for querying does not automatically encode url, we need to provide the password in encoded form in accordance to standard html url encoding.
{% endhint %}

This is available through "Sign document" method, by adding "encrypt" parameter. The detailed implementation setup with example is available at:
